하이브리드 파워트레인의 엔진 재시작 및 감속 구간에서 탄화수소 배출물 및 엔진 제어 특성 분석 = Analysis of HC Emission and Engine Control Characteristic on HEV Powertrain during Engine Restart and Deceleration Driving

다국어 초록 (Multilingual Abstract)

Stringent regulation of exhaust emission and improvement of fuel economy have become major issues in the automotive industry. Hybrid electric vehicle (HEV) can be one of the crucial alternative plans over current conventional vehicle, but they have drawbacks such as the increase of engine out total hydrocarbon (THC) emissions and the deterioration of combustion stability at frequent engine stop and restart. This study performs experimental investigation to obtain a better understanding of THC emission characteristic at engine restart and deceleration driving on a HEV powertrain of parallel motor/generator type. Using a fast response Flame Ionization Detector (FFID) and specified tool for cycle by cycle and cylinder to cylinder, the combustion and engine control characteristic was analyzed during transient state of hybrid powertrain. The experimental conditions cover variation of high voltage battery State of Charge (SoC), spark ignition timing and injected fuel mass. As an experimental result, we can unearth the effects of spark ignition timing and injected fuel mass control for combustion stability during engine restart.
