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.
