Abstract

In an internal combustion engine in which the fuel supply is interrupted during no-load operation to save gas the ignition timing is retarded following resumption of the fuel supply to cause the resumed torque to be applied slowly. A sequence of ignition timing signals following the activation of the gas pedal is delayed by sequentially smaller and smaller amounts until the normal ignition timing is resumed.
