摘要：
Each combustion chamber of an internal combustion engine is equipped with at least two simultaneously working spark plugs which are arranged distant from each other and located out of a central region of the combustion chamber, and an exhaust recirculation circuit including a flow control valve is arranged to recirculate exhaust gas to a nearly stoichiometric air-fuel mixture to be fed to the engine at a high recirculation rate on the maximum of 12-40% by volume of the quantity of air drawn into the engine.
