ABSTRACT:
A fuel injection device of an engine for a vehicle having a power transmitting system connected between the engine and the drive wheel. The relative angle of torsion between the opposed ends of the power transmitting system is maintained at the converging angle of torsion determined by a required amount of fuel when a cruising operation of the engine is carried out. When the required amount of fuel is changed from a first required amount of fuel to a second required amount of fuel, a pre-injection is carried out prior to the main injection. The amount of fuel and the injection time of the pre-injection and the start time of the main injection are determined so that the relative angle of torsion becomes equal to the converging angle of torsion determined by the second required amount of fuel when the main injection is started, and that the relative angle of torsion is maintained at the converging angle of torsion determined by the second required amount of fuel after the main injection is started.
