付け部周辺の燃焼室壁面とが直角に交わらない形
状の燃焼室に、側方電極付根部を環状に延長した
点火プラグを該側方電極付根部が全周にわたつて
燃焼室壁面から燃焼室内に突出するように取付け
、また上記の構成によつて生じるＭＢＴ点火時期
の遅れに対応して低回転高負荷運転域及び機関温
度の低温域における点火時期を遅らせるように点
火時期制御を行う制御手段を備えたエンジンの点
火装置。 A spark plug with a side electrode base extended in an annular shape is installed in a combustion chamber in which the installation center line of the spark plug and the combustion chamber wall around the installation part of the spark plug do not intersect at right angles. It is installed so that it protrudes from the combustion chamber wall surface into the combustion chamber over the entire circumference, and in response to the delay in MBT ignition timing caused by the above configuration, the ignition timing is adjusted in the low rotation, high load operating range and in the low engine temperature range. An engine ignition system equipped with a control means for controlling ignition timing to delay the ignition timing.
