Dual Port Induction System for DMB 1.4 MPI Engine
Abstract
The paper presents the research results of DMB 1.4 l spark ignition engine equipped with prototype variable induction system. 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.
