As a result, the difference between successive amounts of fuel to be injected is never large. of fuel injected lastly. According to the present invention, it is possible to control the air-flow ratio to the optimum value when the method for calculating the amount of fuel to be injected changes between the L-jetronic method and the D-jetronic method in response to engine operating condition changes, even during an acceleration or deceleration.
