PURPOSE:To prevent engine strike and hunting and to improve stability by thinning out fuel injection for each cylinder for every set cycle at the time of a high rotation high load driving state of an engine within set time after starting or within set temperature at the time when a cold state of the engine is discriminated at the time of starting the engine. CONSTITUTION:In a control device 51, to an input port of an I/O interface 56, various kinds of sensors 22, 41-43, 45, 46, 48, 50 and others to respectively detect driving states of an engine are connected. In the meantime, to an output port, an injector 23, a PTC heater 33d is oppositely provided in the fuel injection direction of the injector 23 and others are connected. In this case, the control device 51 discriminates whether the engine is in a cold state or not at the time of starting the engine. Additionally, at the time when it is in the cold state, the control device 51 measures elapsed time after starting or computes a temperature rising amount. Furthermore, within set time after starting or within set temperature, whether the engine is in a high rotation high load driving state or not is discriminated. Additionally, at the time when the engine is in the high rotation high load driving state, fuel injection is thinned out for each cylinder for every set cycle. |
