Method for operating a multi-cylinder jump-spark ignition engine and operation control system thereof

摘要

In a non-load operation of a multi-cylinder internal combustion engine, both suction flow of newly supplied air-fuel mixture to be introduced in a first combustion chamber and exhaust flow of combustion gas to be exhausted from the first combustion chamber or only the exhaust flow is throttled to carry out compression ignition combustion in the first combustion chamber, while suction flow of newly supplied air-fuel mixture to be introduced into a second combustion chamber is blocked to stop combustion in the second combustion chamber to increase a gas feed rate in the first chamber, to thereby cause a kind of run-on phenomenon in the engine in non-load condition.
