PURPOSE:To prevent a fuel from being oversupplied without degrading acceleration performance, by performing asynchronous injection at an asynchronous injection interval set on the basis of the temperature of an engine, in a system wherein asynchronous injection is performed in accordance with an accelerating condition. CONSTITUTION:In a system wherein a fuel injection valve 7 is operated to inject a fuel asynchronously when a controlling circut 61 detects an engine accelerating condition from a time differential value of the pressure in an intake pipe detected by an intake pipe pressure sensor 11, a time differential value of the opening of a throttle valve detected by a throttle valve position sensor 2 or the like during operation of the engine, an asynchronous injection interval which is set in accordance with a cooling water temperature signal S6 from a cooling water sensor 37 when the accelerating condition is detected and which is set to be shorter as the cooling water temperature is lower is read out from a map stored in a memory. The asynchronous injection is performed at the asynchronous injection interval. Accordingly, the fuel can be prevented from being oversupplied, without degrading operating performance at the time of acceleration. |
