Abstract

The article discusses the analysis of the influence of the connecting hole diameter on the amount of the mixture, flowing from the basic volume to the additional volume at the compression stroke in the prechamber engine. The resulting mathematical model allows one to accurately determine the amount of fresh charge, overflowing from the main combustion chamber into the secondary chamber at the compression stroke. The quantity of overflowing charge, taking into account the presence of throttling, allows one to determine the composition of the air-fuel mixture in the main and additional combustion chambers. Owing to the obtained results, it becomes possible to select the optimum mixture composition by adjusting the amount of fuel supplied. The experimental data on the immunity of the thermodynamic cycle of the upgraded engine to different sorts of fuels within a wide range of octane numbers and their viscosity by optimizing the air coefficient in the additional chamber without departing from the optimum ignition limits in all load conditions are given.
