흡기포트 분사방식의 가솔린 엔진에서 급가속시 연료 거둥에 관한 연구

다국어 초록 (Multilingual Abstract)

In this paper, the fuel transport characteristics during transient condition was studied by using a Fast Response<br/>
Flame Ionization Detector(FRFID). The fuel mass delivered to the cylinder in each cycle in the engine transient was<br/>
calculated by using in cylinder HC concentration and air flow model. In order to estimate the transportation of<br/>
injected fuel from the intake port into cylinder, the wall wetting fuelmodel was used. The two coefficient( , ) of the<br/>
wall-wetting fuel model was determined from the measured fuel mass that was inducted into the cylinder at the first<br/>
cycle after injection cut-off.<br/>
To reduce a air/fuel ratio fluctuation during rapid throttle opening, the appropriate fuel injection rate was obtain<br/>
from the wall wetting model with empirical coefficients. Result of air/fuel ratio control, air/fuel excursion was<br/>
reduced.
