In recent decades, due to the need to enforce laws regarding emissions and increasing concern over greenhouse gas emissions from internal combustion engines, natural gas is a viable alternative fuel for power plants, marine propellants and so on.... is of interest. Therefore, the effort to develop gasoline engines as an alternative to gasoline engines, especially diesel engines, has increased because these engines have lower emissions than diesel engines, and lower emissions cause a greater propensity for production. And these engines have been developed. On the other hand, in recent years many efforts have been made to increase the efficiency of gasoline engines to address their weaknesses with diesel engines.
Heavy-duty gasoline engines are often produced by the development of diesel engines, which include changing parts of diesel engines or adding new parts to diesel engines, thereby achieving a new and fuel-efficient engine. Considering the work done in the field of gasoline engine development to increase efficiency and reduce emissions in this paper, we examine the effects of using a pre-combustion mechanism as one of the most effective technologies to increase efficiency and reduce emissions on a The HIMSEN 35/40 Heavy Diesel Engine is manufactured by Hyundai Korea The set is discussed, focusing on the change in the geometrical parameters of the pre-combustion chamber used in the gas engine.
The pre-combustion mechanism of the combustion engine is one of those technologies that is added to a heavy diesel engine to make it more efficient and efficient to use gaseous fuel. This is done by simulating CFD computational fluid dynamics and Conover software, and investigating the effect of changes in different pre-chamber geometrical parameters on engine performance compared to pre-chamber and non-chamber conditions. From these simulations, a suitable and effective pre-compartment configuration is suggested. In general, the influence of geometrical parameters and in particular the dimensions of the pre-compartment on its performance are expressed as two dimensions of the ratio of nozzle length to diameter and the ratio of pre-compartment volume to the volume of the main compartment after numerous simulations and investigations. The results show better performance for the HIMSEN 35/40 gasoline engine with a nozzle length/diameter ratio of 5 and a pre-chamber volume ratio of 0.01.
