| The paper reports the results from the simulation on how the distribution of an air-gas mixture in a diesel engine combustion chamber is impacted by an injection start angle. The research object is the 1CA90 CI engine with a single cylinder. This four-stroke engine is dual fuel, based on LPG and a diesel fuel. A 3D model of a combustion chamber developed with AVL Fire software is studied. The air-gas mixture distribution in a combustion chamber after injecting an initiating diesel fuel dose is analysed. The results show that changing a gaseous fuel injection start angle can significantly influence the distribution of an air-gas mixture in a diesel engine combustion chamber. Despite considerable charge turbulence, the discrepancies in gas concentration depending on injection timing are noticed. Thus, the paper specifies the values of these discrepancies and areas with a rich mixture. |
