ABSTRACT:
A fuel cut-off apparatus is used with an electronically-controlled fuel injection system of the type in which metering of fuel in accordance with the operating conditions of an engine is controlled by the pulse time width of an injection pulse signal applied to electromagnetic fuel injectors. The fuel cut-off apparatus includes a delay circuit, whereby when a fuel cut-off condition is attained during deceleration periods of the engine, the fuel supply to the engine is cut-off after a predetermined time delay.
