IDI 압축 착화기관에서 동물성 유지를 이용한 바이오 디젤의 연소 특성 연구

다국어 초록 (Multilingual Abstract)

Due to environmental pollution and depletion of fossil fuels, research of eco-friendly energy source that can replace the fossil fuels being actively performed. Although biodiesel by vegetable oil has been produced, the interest in the animal fats is increasing due to the food shortages and rise of grain price. In this study, we have performed for exhaust emission and combustion characteristics of indirect injection (IDI) compression ignition engine by using lard biodiesel 5-30% mixture of diesel at various engine speeds and operational conditions. We have obtained that the results of engine performance operated by lard biodiesel at various engine load and speed was slightly decreased, but brake specific energy consumption (BSEC) at using lard biodiesel below 15% was better than diesel fuels. When the mixing ratio of biodiesel increased, PM was a significantly reduced. However, NOx was a slight increase. Therefore, that the biodiesel of animal fats is available for alternative fuel of diesel engine was confirmed.
