Abstract
A fuel injection control apparatus for a diesel engine is provided which works to determine the number of a sequence of injection events to inject fuel into the engine in each operating cycle of the engine and increase it based on the temperature of an injector drive circuit. When the temperature of the injector drive circuit is relatively low, the apparatus increases the number of injection events to decrease the degree of combustion in the engine, thereby reducing the combustion noise of the engine.
