Abstract
A combustion controller for an internal combustion spark ignition type two-cycle engine includes exhaust passage opening ratio adjusting means for adjusting an exhaust passage opening ratio, wherein the exhaust passage opening ratio adjusting means is driven to adjust the exhaust passage opening ratio at a value corresponding to an engine speed and a throttle valve opening ratio at least in a low load operational area. And fresh mixture in a combustion engine is self-fired with a firing timing desirable for operation of the engine. In this engine, the combustion controller includes ignition timing adjusting means for adjusting an ignition timing; abnormal combustion detecting means for detecting abnormal combustion in the combustion chamber; and control means for controlling the exhaust passage opening ratio. The ignition timing at respective values eliminates the abnormal combustion on the basis of the detection signal from the abnormal combustion detecting means.
