摘要:
In order to compensate for the effect of a by-pass passage which by-passes air about the engine throttle valve when a predetermined vacuum prevails downstream thereof, or the delay in air flow within the induction system in response to the demand for engine power, a target torque value is derived based on the engine speed and the accelerator pedal depression amount and this value is used in connection with one or both of the fuel supply and the air flow control. In some embodiments two basic injection pulses are developed and one is selected to suit the instant induction conditions. In other embodiments, selectively delayed target torque values are used to individually modify the throttle valve control and injection fuel supply amount.
