ABSTRACT:
A control unit senses when a gear change command signal is generated and thereupon interrupts the supply of fuel to the engine for a predetermined time, for example about 100 milliseconds. Upon down-shifting, the interruption of fuel supply is delayed to permit the engine to accelerate, thereby simulating double clutching the engine. Fuel supply is interrupted by interrupting injection pulses to an electronic fuel injection system or, if the engine is carburetor-equipped, by supplying air to a bypass connected to the carburetor.
