AB  - This paper presents failure analysis of the connecting rod used in a 12-cylinder diesel engine set on a special vehicle. The fracture of the connecting rod occurred during the engine test in laboratory conditions. Chemical and metallographic analysis as well as mechanical testing have confirmed that the material properties of the connecting rod met the requirements of standard specification and technical documentation. Linear finite element (FE) analysis was performed to evaluate stress state of the connecting rod under maximum load. The results of FE analysis showed that the position of the fracture is consistent with the zone of highest stress. Fractographic analysis has not been able to reveal the main cause of mechanism of fracture due to substantially damaged fracture surface. Inadequate machining, absence of polishing and highest stress in the region of fracture were identified as the main causes of failure. Finally, the engine had been working at maximum load for a longer period of time that also led to the breakage of the connecting rod.

AB  - The paper analyses the possibility of revising the existing maintenance program of special vehicle engine by applying RCM methodology. The main objective in considering the application of the new maintenance methodology was to improve the effectiveness and efficiency of the maintenance of the internal combustion engine, retaining the required reliability of the engine. Analysis was carried out on the fuel supply engine subsystem, which is the most critical engine subsystem from the standpoint of the number of failures in the observed period during its exploitation. As a result of these systematic analyses, the maintenance concept of the critical parts and assemblies of the fuel supply subsystem were selected and the intervals of realization proposed maintenance activities in accordance with a predefined request that the reliability of the fuel supply engine subsystem is not less than 0.985. Based on the results, the conclusion is that the application of RCM for special vehicle engine would be justified since it would contribute to improving the effectiveness and efficiency of maintaining the engines.

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).
