AB  - Biodiesel is one of the promising renewable, alternative, and environmentally friendly biofuels that can be used in Diesel engine with little or no modification in the engine. The present paper investigates the combustion characteristics of single cylinder, naturally aspirated, air cooled, Diesel engine fueled with pure (100%) methyl ester of rapeseed oil, comparing to the corresponding characteristics when it was driven by diesel fuel. Combustion process analysis for both fuels was done at constant engine speed and at two load levels corresponding to the mean effective pressure of three and six bar. It was also concluded that the test engine can operate without problems, both with that fuel and with a lot of other biofuels and their mixtures that were used during long laboratory research.

AB  - This paper considers the analysis of energetic and environmental aspects of electric drive vehicles application in Serbia. The analysis implies real conditions of road transport and electricity production in our country and evaluates the estimation of energy consumption and CO2 emission (Well-to-Wheel), under the assumption of hypothetical transition from classic internal combustion (IC) engine to pure electric drive of vehicles. For this purpose the real estimations of IC engines efficiency under the road conditions of operation and the global efficiency of electric drive system (electricity production, transmission network, battery and electric motor) were necessary. The results show that in the case of present reality of electricity production from coal (lignite), CO2 emission would be even higher. However, under the assumption of significantly more efficient electricity production (for example using combine cycle of gas turbine – CCGT), CO2 emission would be decreased. In this paper some experimental data of city bus fuel consumption and efficiency measurements are also presented.

AB  - This paper presents the quick, simplified method for
the evaluation of heat release rate and combustion analysis on
the bases of in cylinder pressure record in IC engine. The method
is based on the approach proposed by Hohenberg and Killman,
and it is extended by dint of the evaluation of heat transferred to
the cylinder walls omitted in original approach. Therefore, the
complete heat released by fuel combustion was considered. The
accuracy of the method was also analyzed and it is shown that
errors caused by the simplifications in the model were very
small. In order to demonstrate the method it was applied for the
heat release analysis of tested diesel engine fuelled by standard
mineral diesel fuel and pure biodiesel fuel. Combustion
characteristics of two applied fuels were analysed and compared.

AB  - Klasični zahtevi: velika snaga, oblik krive momenta, trajnost, pouzdanost,niska proizvodna cena,
itd. su u savremenoj motornoj industriji i dalje veoma važni ali nisu dovoljni u modernom razvoju
motora. Potrošnja goriva, izduvna emisija i emisija buke postali su važni parametri, ne samo u smislu
konkurentnosti motora, već su takođe podvrgnuti zakonskoj regulativi koja postaje sve oštrija svakih
nekoliko godina. Da bi se ispunili svi ovi zahtevi potrebna su sveobuhvatna znanja o kompleksnimhemijskim i fizičkim procesima koji se odigravaju tokom transformacije energije u radnom prostoru
motora, u cilju karakterizacije kompleksnih uticaja i pronalaska pravaca poboljšanja i optimizacije
procesa, i , po mogućstvu , izbegavanja neželjenih efekata.
Sagorevanje u motoru je ključni proces koji krucijalno utiče na performanse motora (snagu,
moment, specifičnu potrošnju goriva), kao i na ekološke karakteristike motora, tj.izduvnu emisiju i
emisiju buke. Snaga, moment i potrošnja goriva se normalno mere tokom ispitivanja motora, i, ako je
potrebno, sastav izduvnih gasova, buka itd., tako da se globalna efikasnost motora može utvrditi.
Međutuim, sofisticiranije informacije o događanjima u cilindru su potrebne kako bi se dobio uvid u
izvore i distribuciju gubitaka energije, formiranja toksičnih komponenti izduvnih gasova i sl.

AB  - This paper analyzes the potential problems in the exploitation of the older generation of spark-ignition engines with higher octane number of petrol (unleaded petrol BMB 95) than required (leaded petrol MB 86). Within the experimental tests on two different engines (STEYR-PUCH model 712 and GAZ 41) by applying piezoelectric
pressure sensors integrated with the engine spark plugs, acceleration sensors and
special electronic block connected with distributor, show that the cumulative first
and second theoretical phase of combustion when petrol of higher octane number
(BMB 95) is used lasts slightly longer than when the low-octane petrol MB 86 is
used. For new petrol (BMB 95) higher optimal angles of pre-ignition have been determined by which better performances of the engine are achieved without a danger
of the combustion with detonation (also called knocking).

AB  - In this paper, novel method for obtaining information about combustion process in individual cylinders of a multi-cylinder spark ignition engine based on instantaneous crankshaft angular velocity is presented. The method is based on robust box constrained Levenberg-Marquardt minimization of non-linear least squares given for measured and simulated instantaneous crankshaft angular speed which is determined from the solution of the engine dynamics torque balance equation. Combination of in-house developed comprehensive zero-dimensional two-zone spark ignition engine combustion model and analytical friction loss model in angular domain have been applied to provide sensitivity and error analysis regarding Wiebe combustion model parameters, heat transfer coefficient, and compression ratio. The analysis is employed to evaluate the basic starting assumption and possibility to provide reliable combustion analysis based on instantaneous engine crankshaft angular speed.

AB  - The In-cylinder pressure profile contains valuable information on the combustion process and its availability is greatly desirable in closed loop IC Engine control systems. The low lifetime and high costs of the currently available sensors are still preventing high-volume production of in-cylinder based engine control system. This paper deals with the potentials of Artificial Neural Networks (ANN) and their application in combustion features extraction, based solely on the crankshaft angular speed measurements. The focus of this paper is put on two concepts of ANN, based on a radial basis function (RBF) and a local linear Neuro-fuzzy models (LLNFM) and their applicability in virtual sensing of crucial combustion process parameters. Training and validation of the suggested ANN models is based on comprehensive engine test bed data set.

AB  - Due to the significant share of Internal Combustion Engines (ICE) in global energy demand, primarily through the transportation sector, great efforts are invested in research for solutions that will increase the fuel economy of ICE-powered vehicles. Several directions, most prominently that of Hydraulic Hybrid Technology, are considered for achieving pronounced powertrain efficiency breakthroughs on heavy vehicles in the near and mid-term. However, even simpler hybrid solutions, such as those employing an ultracapacitor-based energy accumulator, may provide significant fuel economy improvements at diminished implementation costs. In this paper, considerations regarding the use of such a system are laid out. A data acquisition on a transit bus circulating on Belgrade’s transportation system has been performed in order to evaluate the real driving cycle and obtain the powertrain parameters necessary for calibrating a high-fidelity AMESim model of the vehicle. Initial study shows that considerable fuel consumption reduction in excess of 15% could be achieved by implementing a regenerative hybrid system employing an ultracapacitor-based accumulator.

AB  - A non-linear, angle-resolved, multi-cylinder SI engine computational model has been developed for predictions of instantaneous crankshaft speed and torque. The computation is firmly based on high-fidelity, comprehensive thermodynamic, steadystate, Two-Zone, Zero-Dimensional combustion model followed by a detailed analytical component model of engine friction and mechanical losses. Predictions of both engine cranking and steady-state operation conditions reveal strong dependence of variable engine moment of inertia and crankshaft instantaneous speed signal. The uncertainties and variation in the masses of the reciprocating slider mechanism components are further analysed in order to establish the impact on the instantaneous torque and speed profile. Self-tuning concept based on Levenberg-Marquardt Box-Constrained Optimisation algorithm has been introduced for model parameter identification.

AB  - The AMESim model of motor vehicle driving simulation has been applied on a transit bus to investigate the potentials for fuel economy improvement. With the purpose to calibrate the simulation model and to evaluate the real driving cycle, a data acquisition using vehicle CAN bus has been performed on a transit bus in real driving conditions. This was the basis for constructing a high-fidelity AMESim simulation model of the vehicle for subsequent hybrid systems simulations. It was observed that a great fraction of the total fuel mass was consumed when the bus was stationary. Initial simulation study shows that fuel consumption reduction in excess of 12% could be achieved by implementing a relatively simple start/stop micro-hybrid system. Also, braking energy reaches cca. 60% of the energy released by the engine, representing a potential basis for the application of regenerative braking hybrid system.

AB  - Modern and advanced control systems for internal combustion engines require accurate feedback information from the combustion chamber. Whereas the in-cylinder pressure sensor provides this information through its close thermodynamic ties with the combustion process, drawbacks in its implementation push research towards other non-intrusive sensing methods. This paper suggests alternative methods of combustion phasing detection relying on measured angular crankshaft speed. Method developed, achieves sensing of angular position of the 50% of mass fraction burned (MFB50) through two steps: calculation of, so called, synthetic torque and its non-linear transformation to a combustion feature estimator through local model. In order to calibrate both parts of this virtual combustion sensor, parameters of a high-fidelity crankshaft dynamic model are identified, and the linear neuro-fuzzy based model is trained with extensive experimentally collected data set. Created virtual MFB50 sensor, demonstrated its performance, on a large test data set comprised of 70% of gathered data.

AB  - Most frequently used approach to describe combustion process in IC engines is based on Wiebe function. Its parameters are strongly influenced by geometric and in-cylinder gas- and thermodynamic processes and can’t be predicted easily and with sufficient accuracy using available empirical relations. Along with deterministic methods lacking in systematic approach, indirect analysis methods based on minimization of error between simulated and measured in-cylinder pressure have been successfully demonstrated. In this paper the same concept is introduced to identify combustion model parameters of a multi-cylinder SI engine based on box constrained Levenberg-Marquardt minimization of nonlinear Least Squares (LSQ) given for measured and simulated instantaneous crankshaft angular speed determined from the solution of the engine dynamics torque balance equation. For predictions of gas pressure and engine torque, a nonlinear, detailed, angle resolved twozone, zero-dimensional multi-cylinder SI engine combustion model has been developed as well as a detailed analytical component model of engine friction and mechanical losses. The models are used to analyse the influences of engine combustion and dynamics model parameters on instantaneous crankshaft speed and to investigate biases in measurement in order to recognize and establish the constraints in process of combustion model parameters identification.

AB  - An involvement of the Internal Combustion Engines Department in the support activities to the University of Belgrade Formula Student team provided an opportunity to conduct some tests and research in the field of the engine control parameters optimization on a specific racing class engine –Yamaha YZF-R6s. The main goal of this research was getting optimal look-up tables for ignition timing and fuelling in order to obtain maximal performance in terms of effective torque and power of the air-flow restricted version of the engine, used in Formula Student competition vehicle. In order to improve accuracy and provide more detailed calibration data a model based approach is suggested with a detailed 1D thermodynamic model as a basis for additional testing point simulation. The method developed, provides a mean for model calibration to be based solely on data available from the limited number of measured engine effective parameters. This approach shows that a lack of test point data, due to test bench equipment limitations, can be successfully overcomed in engine optimisation process by using model based approach. Furthermore, the method used, demonstrated a capability of identifying combustion process parameters without in-cylinder pressure measurements and analysis.

AB  - The in-cylinder pressure analysis provides important information on the combustion process and stands as an invaluable tool in the internal combustion engine research & development. Its implementation in a combustion control algorithms appears as a promising solution for attaining optimal combustion control in IC Engines. The pressure sensor durability, accuracy and price, along with increased demand for the processing power of Engine ECU, seems to be the main obstacles for putting these concept in IC engines on serial production line. This paper deals with the potentials of Artificial Neural Networks (ANN) and their application in combustion features extraction, based on the crankshaft angular speed measurements. High speed processing capabilities and acceptable accuracy of ANN make them good candidates to become a core component of the future combustion control algorithms. An radial basis function (RBF) ANN and a local linear Neuro-fuzzy model (LLNFM) are compared in order to gain some conclusions on optimal network topology, best suited for job of extracting crucial combustion features on common ECU platforms.

AB  - Internal combustion engines account for approximately a quarter of global energy demand. The primary reason is the very high reliance of the transportation sector on fossil fuels. Reducing IC Engines' environmental impact and fuel consumption is one of the directions taken by vast research efforts aimed at increasing the sustainability of the transportation sector. One of the possibilities is the use of a charge-air cooling process - turbo-expansion, to raise efficiency by harnessing more exhaust energy and raising the intake charge density. It allows intake-air temperature to be lowered to around, or even below, ambient levels and exempts the turbocharger system from using a wastegate. A co-simulation in WAVE and MATLAB/Simulink environments was conducted to investigate the effects of the turbo-expansion concept on gas-exchange and combustion processes of a small, 1,4 L spark-ignition turbocharged engine. An empirical, operating conditions-correlated, Wiebe-based spark-ignition combustion model was used to predict the influence of intake and exhaust conditions on combustion duration and heat release dynamics. The implications on the engine gas-exchange processes are quantified. Despite significant intake charge cooling effect not being conveyed inside the cylinders, the brake specific fuel consumption is predicted to be reduced by 1,8 % at 4500 RPM.

AB  - The current paper presents an original method for evaluating the variable mass moment of inertia of the piston-crank mechanism of an internal combustion engine based on the principle of kinetic energy equality of the real mechanism and its reduced model. The method has been developed to evaluate the variable mass moment of inertia of a 12-cylinder V-engine having a piston-crank mechanism with main and auxiliary connecting rods. In order to study the influence of the piston-crank mechanism configuration on mass moment of inertia variability, the procedure has been also applied on virtual 'shortened' variants: 2-cylinder and 6-cylinder V-engines with main and auxiliary connecting rods, and a 6-cylinder in-line engine with simple piston-crank mechanism. The results are compared with values obtained using the usual simple method for determining the approximate constant mass moment of inertia based on Huygens-Steiner theorem. It is shown that there is negligible difference between the constant value obtained by the simple method and the mean value of variable mass moment of inertia evaluated using the proposed model. Variability of mass moment of inertia is relatively small for a large number of cylinders, but it rises with cylinder number reduction. The presented method with appropriate modifications may be applied to any piston-crank mechanism arrangement.

This variable geometry induction system was developed in order to investigate the possibilities of improving induction generated swirl and turbulence in combustion chamber and in this way to accelerate combustion, especially at low load engine condition. Induction channel in engine head was separated longitudinally into two sections using thin tin longitudinal wall and deflector valve at channel entrance was used to direct air flow into half channel cross section (at low engine load) or to enable full channel cross section (at full load). The results of combustion analysis show that combustion is accelerated and cycle variations are reduced at certain working conditions. In addition, specific fuel consumption is reduced, but very small, smaller than it was expected. Further geometry optimization and appropriate process managing is required.

AB  - IC engines amount to 25% in global energy consumption, which is mostly due to their massive share in road transport of approximately 99%. The motivation for development of fuel efficient vehicle propulsion systems arises from strong dependence of the transportation sector on fossil fuels and the need for a rapid response to the global warming challenge. Hybridization has, globally, proven its capabilities in enhancing the powertrain efficiency and is the only technology offering significant breakthroughs in near and mid-term. While there are a number of approaches, Hydraulic Hybrid Technology (HHT) has been lately utilized as an alternative power source for vehicles. HHT gives unique advantages for easy and cost-effective implementation in current production vehicles as well as an aftermarket solution. It seems to be the replacement for expensive, bulky and environmentally hazardous battery technology. Hydraulic energy conversion and storage provide exceptional power density and efficiency making them ideally suited for regenerative powertrain design. It is particularly efficient in city traffic conditions, characterized by frequent stops, coasting and long idling periods. Additionally, emissions are reduced, particularly at idling and low speeds, compared to conventionally powered vehicles. While HHT is still in the prototype and simulation stage, this paper reviews current state-of-the-art.

AB  - This paper presents the procedures for measuring and analyzing the angular velocity variation of twelve-cylinder diesel engine crankshaft on its free end and on the power-output end. In addition, the paper deals with important aspects of the measurement of crankshaft torsional oscillations. The method is based on digital encoders placed at two distances, and one of them is a sensor not inserted directly on the shaft, i.e. a non-contact method with a toothed disc is used. The principle based on toothed disc is also used to measure the actual camshaft angular velocity of in-line compact high-pressure pump the engine is equipped with, and this paper aims to demonstrate the possibility of measuring the actual angular velocity of any rotating shaft in the engine, on which it is physically possible to mount a toothed disc. The method was created completely independently during long-range development and research tests of V46 family engines. This method is specific for its particular adaptability for use on larger engines with extensive vibrations and torsional oscillations. The main purpose of this paper is a practical contribution to all the more interesting research of the use of engine crankshaft angular velocity as a diagnostic tool for identifying the engine irregular running.

abstract = "This paper presents the procedures for measuring and analyzing the angular velocity variation of twelve-cylinder diesel engine crankshaft on its free end and on the power-output end. In addition, the paper deals with important aspects of the measurement of crankshaft torsional oscillations. The method is based on digital encoders placed at two distances, and one of them is a sensor not inserted directly on the shaft, i.e. a non-contact method with a toothed disc is used. The principle based on toothed disc is also used to measure the actual camshaft angular velocity of in-line compact high-pressure pump the engine is equipped with, and this paper aims to demonstrate the possibility of measuring the actual angular velocity of any rotating shaft in the engine, on which it is physically possible to mount a toothed disc. The method was created completely independently during long-range development and research tests of V46 family engines. This method is specific for its particular adaptability for use on larger engines with extensive vibrations and torsional oscillations. The main purpose of this paper is a practical contribution to all the more interesting research of the use of engine crankshaft angular velocity as a diagnostic tool for identifying the engine irregular running.",

AB  - In this paper some results concerning the evolution of 3-D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from 'omega' to 'simple cylinder' were presented. All combustion chambers i. e. those with 'omega' bowls, with different profiles, and those with 'cylinder' bowls, with different squish area ranging from 44% to 62%, were with flat head, vertical valves, and identical elevation of intake and exhaust ports. A bunch of results emerged by dint of multidimensional modeling of non-reactive fluid flow in arbitrary geometry with moving objects and boundaries. The fluid flow pattern during induction and compression in all cases was extremely complicated and entirely 3-D. It should be noted that significant differences due to geometry of the bowl were encountered only in the vicinity of top dead centre. Namely, in the case of 'omega' bowl all three types of organized macro flows were observed while in the case of 'cylinder' bowl no circumferential velocity was registered at all. On the contrary, in the case of 'cylinder' bowl some interesting results concerning reverse tumble and its center of rotation shifting from exhaust valve zone to intake valve zone during induction stroke and vice-verse from intake valve zone to exhaust valve zone during compression were observed while in the case of 'omega' bowl no such a displacement was legible. During expansion the fluid flow pattern is fully controlled by piston motion and during exhaust it is mainly 1-D, except in the close proximity of exhaust valve. For that reason it is not affected by the geometry of the bowl.

AB  - This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error of existing gravimetric measurement method. Since coarse particles are eliminated by new engine technologies, fine particles, with very negative effects on human health, dominate in the emission of current diesel engine. Therefore, it is necessary not only to measure mass of emitted particles but also to investigate other important particle characteristics as: particles number, particle size, particle number and mass distribution, particle active surface, particle composition, etc. Therefore, existing measurement technologies used in aerosol science can be used also to study diesel engine particles properties. This most common instrumentation in aerosol technique is shortly reviewed in the paper with special attention on candidate instruments included in EU program on portable emissions measurement systems.

AB  - In this paper some results concerning the structure and evolution of fluid flow pattern during induction and compression in 4- valve engines with tilted valves were presented. Results were obtained by dint of multidimensional modeling of non-reactive flows in arbitrary geometry with moving boundaries. During induction fluid flow pattern was characterized with organized tumble motion followed by small but clearly legible deterioration in the vicinity of the bottom dead center. During compression the fluid flow pattern is entirely three-dimensional and fully controlled by vortex motion located in the central part of the chamber. In order to annihilate negative effects of tumble deterioration and to enhance swirling motion one of the intake valves was deactivated. Some positive and negative effects of such attempt were elucidated. The effect of turbulence model alteration in the case of excessive macro flows was tackled as well. Namely, some results obtained with eddy-viscosity model i. e. standard k-ε model were compared with results obtained with k-ξ-f model of turbulence in domain of 4-valve engine in-cylinder flow. Some interesting results emerged rendering impetus for further quest in the near future.
