연료종류 및 시험방법에 따른 PM 입자 특성에 관한 연구

As the interest on the air pollution is gradually rising up at home and abroad, automotive and fuel researchers have been working on the exhaust emission reduction from vehicles through a lot of approaches, which consist of new engine design, innovative after-treatment systems, using clean (eco-friendly alternative) fuels and fuel quality improvement. This research has brought forward two main issues : whether PM emissions should be regulated for diesel and gasoline vehicles and whether gasoline and LPG powered vehicles can be further neglected from PM emission inventories. PM(particulate matter) particle of automotive had many problem that cause of ambient pollution, health effects. The main particulate fraction of automotive exhaust emission consists of small particles. Because of their small size, inhaled particles may easily penetrate deep into the lungs. The rough surfaces of these particles makes it easy for them to bind with other toxins in the environment, thus increasing the hazards of particle inhalation. Based on these characteristics, this paper discusses the influence of gasoline, diesel and LPG fuel on automotive nano-particle exhaust emissions. Also, this paper assesses Nano particle emission characteristics using 3 type test mode. This test mode is CVS-75, HWFET, NEDC mode.
