디젤 SUV에 대한 바이오디젤의 영향성 평가

Biodiesel is already remarkable alternative fuel in many countries. So, many studies are performed on the environmental or economic effects as well as the characteristics of diesel engine fueled biodiesel in combustion and emission. In this paper, the influence of biodiesel fuel is evaluated by doing the fleet test and durability test in diesel SUVs. Vehicle fleet tests, targeted 10,000㎞ mileages, are done by general drivers who has careers above 5 years using their diesel SUVs on actual driving condition with various fueling patterns. In vehicle durability test, targeted 80,000㎞ mileages, used engines and fuel systems are inspected to evaluate the influence of biodiesel such as carbons in cylinder and corrosion in fuel tank or fuel lines. And these vehicles were checked the startability in cold condition, dynamic performance and NVH. As a result, because biodiesel fuel influenced on the performance and the noise of engines or vehicles negatively, many studies will be propel to develop the all system properly for biodiesel on diesel SUV.
