Abstract
An angle of spray of a fuel injection valve is narrowed when a temperature of an internal combustion engine is low, whereas the angle of spray of the fuel injection valve is widened in a low and intermediate load region where the temperature of the internal combustion engine is high. The angle of spray of the fuel injection valve is narrowed and also a spray condition is controlled so that the fuel spray comes unevenly in contact with an exhaust side portion of a valve head of an intake valve, in a high load region where the temperature of the internal combustion engine is high.
