듀얼 스파크 플러그 적용 엔진의 연소 및 연비 특성 연구

Fuel economy is one of the major issues in regard to energy and environment. Customers demand the improvement of fuel efficiency and drive ability. because of this cause, I make an experiment and simulation on DSP engine which can improve fuel efficiency and drive ability. Dual spark plug(DSP) system engine can realized the customers desire. As a result of an engine test, The DSP system engine shows fast combustion and high thermal efficiency. Indicated thermal efficiency of DSP system engine compared with SSP system engine is improved up to 2~4%. Also, DSP system engine shows the improvement of 2~5% fuel consumption rate at the main driving zone. COV indicated drive ability is about 1%. According to a result of simulation, DSP engine appears to be increasing 4.7% fuel efficiency.
