디젤기관의 바이오연료 혼합율 및 바이오 온도변화 대한 배출가스 특성 연구

Abstract

Biofuels are a form of renewable energy and vigorously require research to cope with the changes in international energy supply and demand. Although they only account for a few percent of the worlds transport fuel to date, they are increasingly popular due to higher oil prices and an increasing concern with global warming and investments into them are therefore growing each year. Biofuels are renewable energy and need to be continuously researched to deal with changes in international energy. Therefore, the authors intended to investigate varying biodiesel fuel ratios and biodiesel fuel temperatures to present various uses for biofuels. Engine experiments were conducted with fixed fuel injection timing of BTDC 22°CA using a four-stroke six-cylinder in a direct injection diesel engine. The results of this study demonstrated that as the biodiesel fuel mixture increased, fuel consumption increased slightly, NOx increased, CO decreased slightly, and PM decreased significantly. When the biofuel temperature changed, NOx and PM increased slightly, brake specific fuel oil consumption increased and CO did not change significantly.
