Title:
内燃機関の過渡時燃料噴射制御方法
Document Type and Number:
Japanese Patent JP4325511
Kind Code:
B2
Abstract:
To accurately control the transient fuel injection when many kinds of fuels are supplied.
When high octane number gasoline and low octane number gasoline are individually injected at an arbitrary supply ratio from fuel injection valves 110H and 110L to an air intake port of an internal combustion engine 100, in changing the fuel supply ratio and the engine load, based on each fuel supply ratio, the compensation of the fuel injection amount of each fuel for the variation of the amount of each fuel stuck to the wall surface is performed for each fuel. Thus, regardless of the variation of the fuel supply ratio, the transient fuel injection amount can be accurately corrected.
