흡기가열을 이용한 가솔린 압축착화 엔진의 연소 및 배기특성 모델링

Abstract

This paper presents numerical study on combustion and emissions characteristics of GDICI(gasoline Direct Injection Compression Ignition) engine using intake preheating. Numerical modeling was conducted by using the KIVA-3V Release2 code. In addition, Chemkin Chemistry solver was integrated into KIVA code to simulate the ignition and combustion precesses in order to predict combustion and exhaust emissions characteristics. The fuel was modeled using PRF mechanims to simulate the fuel oxidation process. To achieve gas pressure in cylinder and emissions characteristics, the experiments were performed on a single-cylinder engine. The simulation results agreed well with the experimental data.
