Abstract
An automotive engine is provided with a fuel control system having a fuel injector for injecting a properly controlled quantity of fuel into cylinders of the automobile engine. The control system is adapted to cause the fuel injector to inject an increased quantity of fuel when an engine control value, relative to which the automotive engine changes its speed of rotation for a decision as to whether the automotive engine is in an acceleration state, is higher than a critical level. The control system also detects the transmission coupled to the automobile engine, and changes, when a temperature of the automotive engine is lower than a preselected temperature, the critical level according to the type of transmission detected.
