Abstract
The results of numerical simulation of the resonator installation effect in the intake system of a diesel engine of dimension 21/21 on wave phenomena, technical, and economic indices are presented. The objective of the study is a diesel engine with eight cylinders: the cylinder diameter is 210 mm, the piston stroke is 210 mm. Diesel (factory designation is 8DM-21/21) is produced at the “Ural diesel-motor plant” (Russia, Ekaterinburg). Numerical simulation was performed in the ACTUS software (Switzerland, Baden). The simulation was performed taking into account the geometric parameters of the elements of the inlet system and the gas-dynamic flow nonstationarity. The article briefly describes the functions and designs of resonators used in the field of engine building. It is shown that the resonator installation in the intake system of the 8DM-21/21 diesel engine significantly changes the gas dynamics of the flow. For example, there is a smoothing of wave phenomena. This leads to an improvement in the quality of gas exchange (an increase in the filling ratio up to 0.5%). At the same time, the specific fuel consumption is reduced by an average of 0.3% while maintaining the power of a diesel engine.
