摘要： An internal combustion engine of the reciprocating piston type, which is provided with an exhaust gas recirculation circuit to suppress the formation of NOx and has two or three spark plugs for each combustion chamber. There is a substantial overlap of the opening periods of exhaust and intake valves, so that a portion of the combustion gas is left unexhausted. The combustion chamber has a simple shape such as hemisphere, and the spark gaps of the plural spark plugs are arranged distant from each other in each combustion chamber so as to respectively share approximately equally divided portions of each combustion chamber. The number of the spark plugs is two when the volume of the recirculated exhaust gas, including the unexhausted combustion gas, is about 50% at the maximum of the volume of air admitted into the combustion chamber but three when the recirculated exhaust gas amounts to about 60% of the air at the maximum.

摘要： A dual spark plug ignition engine is equipped with an EGR system. The two spark plugs in each combustion chamber are simultaneously energized to produce sparks to ignite the charge in the combustion chamber under a normal engine operating conditions, whereas the spark plugs are energized with a predetermined phase difference from each other under high power output engine operating conditions.
