Abstract
In a fuel injection apparatus for an internal combustion engine in which the fuel injection timing and the amount of fuel injection are controlled in response to a signal indicative of the operating condition of the engine, the maximum amount of fuel injection is determined in such a way that the engine torque determined by the maximum amount of fuel injection does not change even when the fuel injection timing is adjusted in accordance with the operating condition of the engine.
Claims9
A fuel injection apparatus for an internal combustion engine in which the fuel injection timing and the amount of fuel injection are controlled in response to at least one condition signal indicating the operating condition of the engine, comprising:
- a first control means for controlling the fuel injection timing by timing data provided in response to said condition signal;
- and
- a second control means for controlling the amount of fuel injection in response to said condition signal and timing data concerning the fuel injection timing set by said first control means, said second control means being provided with a first means for producing first fuel injection data for setting the maximum fuel injection amount at each instant and ajusting said timing data in such a way that the engine torque corresponding to the maximum fuel injection does not substantially change even when the fuel injection timing is adjusted by said first control means.
