An internal combustion engine including a combustion chamber, an intake system having an intake valve and an intake passage leading through the intake valve to the combustion chamber for providing a supply of intake gas to the combustion chamber. A valve timing control device is provided for governing opening and closing timings of the intake valve so that the intake valve is closed at a controlled timing in the compression stroke, whereby a controlled amount of the intake gas is returned from the combustion chamber to the intake passage in the compression stroke to thereby control the effective charge to the combustion chamber. A detecting device is provided for detecting at least one factor which is related to engine speed and producing an engine speed signal, and a manually operated reference setting device for determining a reference value together with, an engine overrun preventing device for comparing the engine speed signal with the reference value and retarding the closing timing of the intake valve to thereby decrease the effective charge when the engine speed signal is greater than the reference value.
