Title:
内燃機関において用いられるダイナミックレンジが改良された定速マルチ圧力燃料噴射システム
Document Type and Number:
Japanese Patent JP4808400
Kind Code:
B2
Abstract:
A fuel injection system operates under a predetermined substantially constant pump speed and creates multi-pressure levels by diverting the fuel flow. Fuel pressure can be switched from one steady pressure level to another level on-demand instantly. This superimposes and overlaps typical fuel injection events in the linear operating ranges under different pressure levels, significantly increasing the fuel injection dynamic range. The dynamic range is further increased when another predetermined constant pump speed is assigned. Thus, the system saves fuel and reduces exhaust emission in city driving when gas pedal is released including idle. The same system can instantly deliver additional fuel on-demand for extra power beyond engine rating producing a sport-car-like performance.
