An Effect of Car Performance Influenced to Absorbing Resistane of Air-cleaner Filter for the L. P. G Vehicle of Open Loop Fuel System

Open Loop 연료공급계의 L. P. G 차량에서 공기청정기 필터의 흡기저항이 차량성능에 미치는 영향

The interest and purpose of this study is to control of air-fuel ratio and develop control device of a spark ignition LPG engine with adopting open loop fuel system. The air-fuel ratio is derived by considering airflow resistane of air cleaner element. The result shows that air-fuel ratio becomes more and more rich when airflow resistance increases. Experiments about the influence of airflow resistance on the engine performance, drivability and emissions are performed. Therefore, it is known that open-loop fuel system depends on the absorbing resistance of air-cleaner.
