Patent ID: 8195376

Claim:
A fuel injection control device for a diesel engine having a plurality of cylinders, comprising: a high-pressure pump; a common rail for accumulating fuel pressurized and delivered by the high-pressure pump; a plurality of injectors attached to the respective cylinders of the diesel engine so as to inject the fuel supplied from the common rail into respective combustion chambers in the respective cylinders; a starter for cranking the diesel engine by use of electric power of a battery, wherein the starter starts the cranking by turning on an engine starting switch; a setting means for setting a non-fuel injection time; an air heater disposed at an inlet of an intake manifold of the diesel engine so as to warm an intake air introduced into the inlet; and a control means that controls the high-pressure pump, the injectors and the starter so as to continue the cranking without fuel injection until lapse of the non-fuel injection time, and so as to command one of the injectors to perform an earliest fuel injection after the lapse of the non-fuel injection time, wherein, when the air heater is operated to warm the intake air, the injector commanded to perform the earliest fuel injection is an injector attached to the cylinder which is closer to the air heater than any other cylinder so as to have a highest intake air temperature of intake air temperatures of all the cylinders.
