Method for controlling fuel injection for automotive engines

摘要

A basic fuel injection time is obtained based on engine speed and intake-air pressure in an intake passage of an engine downstream of a throttle valve of the engine. The basic fuel injection time is corrected by a correcting value based on a constant for a fuel injector and capacity of a chamber formed in an intake passage and on variation in intake-air pressure at every one rotation of a crankshaft of the engine when the idling state of the engine or throttle rapid closing are detected.
