Abstract
Fuel is periodically injected into an engine combustion chamber by a first injection device as an engine crankshaft rotates. A timing control device serves to adjust the timing of fuel injection effected by the first injection device with respect to the rotational angle of the crankshaft. Fuel is also periodically injected into the combustion chamber by a second injection device as the crankshaft rotates. Adjustment of the timing of fuel injection effected by the first injection device results in variation of the total fuel injection rate characteristic curve with respect to the rotational angle of the crankshaft.
