Abstract
A fuel injection control device for a diesel engine controls the first fuel injection timing so as to reduce the amount of white smoke generated in large amounts immediately after starting an engine. The fuel injection control device for the diesel engine comprises a high-pressure pump, a common rail for accumulating a highly-pressured fuel, injectors for injecting the fuel into a combustion chamber and a control means. Due to the fuel injection control device for the diesel engine, the fuel injection is performed after the cranking, without injecting the fuel for a certain period of time after an engine starting switch is turned on so that the pressure in the common rail becomes a set value.
