Influence of Fuel Injection on Gasoline Engine Performance

摘要: Because of the most common method preparing fuel-air mixture for gasoline-fueled engines is port fuel injection (PFI). For reducing wall-film entering cylinder in liquid phase, phenomena phase should be at minimum lever or avoided. So first thing learning to detect way cylinder. Therefore, enter detected by changing temperature location and time evaporated. Then validated experiment test bed it improved that feasible. At end influence timing ratio on engine performance studied based bed.The results show regardless expansion stroke intake delay will decrese power and  make emission deterioration meanwhile twice can improve film evaporation resulting high-speed airflow charge.
