A combustion control apparatus for a spark ignition type 2-cycle internal combustion engine includes fresh air mixed with fuel in a combustion chamber which can be self-ignited at an ignition timing preferable for the operation of the internal combustion engine at least in a low load operation region to effect active thermal atmosphere combustion. When it becomes necessary to stop the internal combustion engine quickly, upon starting of the internal combustion engine again, the starting performance is high. A combustion control apparatus for a spark ignition type 2-cycle internal combustion engine includes fresh air mixed with fuel in a combustion chamber which can be self-ignited at least in a low load operation region. The exhaust path opening adjustment means is driven upon development of a stopping signal for the internal combustion engine, if the internal combustion engine speed is higher than a predetermined speed above idle, so that the exhaust path opening is higher than an opening at which self-ignition is impossible. When the internal combustion engine stopping signal is developed, when the internal combustion engine speed drops until it becomes lower than the predetermined speed, the exhaust path opening adjustment means is driven so that the exhaust path opening is controlled to an opening at which ordinary combustion is possible. |
