영어 초록

Increasing specific power, torque and high responsibility have come to the fore as the important strategy of reducing fuel consumption in vehicle engines. Therefore, the boosting performance of various boosting devices has been investigated using a diesel engine simulation program. For the comparison of boosting performance, the simulation result of a naturally aspirated 2.0 liter engine is used as a basis. Subsequently, the boosting effects of single turbocharger, single supercharger and 2-stage boosting system combined with a turbocharger and a supercharger are compared at the same engine condition. The simulation results show that the 2-stage boosting system can attain lower specific fuel consumption and higher air mass flow. In low engine speed range, a supercharger mainly leads higher boosting performance with higher responsibility in the combined boosting system.
