Abstract
There is disclosed an internal combustion engine in which synchronous fuel injection is conducted at every predetermined crank angle and an asynchronous fuel injection is conducted regardless of the crank angle. The engine is provided with an electronical control circuit which computes a quantity of fuel to be injected in each synchronous fuel injection on the basis of a load applied to the engine and an engine speed. A variance of intake pressure in said engine is computed. The computed variance is compared with a reference level which is determined to be greater as the intake pressure becomes higher. In the case of detection of the variance of the intake pressure being greater than said reference level, said quantity of fuel to be injected is increased.
