ENGINE IGNITION DEVICE

PROBLEM TO BE SOLVED: To improve responsiveness of ignition timing with respect to a user request.SOLUTION: An engine ignition device which controls ignition timing corresponding to engine speed according to an ignition timing characteristic includes: user request detection means 11 having a high advance ignition timing characteristic 40 and a low advance ignition timing characteristic 41 for controlling the ignition timing after start, and for detecting a user request; and ignition timing switching means 35 for switching from the low advance ignition timing characteristic 41 to the high advance ignition timing characteristic 40 when the user request detection means 11 has detected an acceleration request, and for switching from the high advance ignition timing characteristic 40 to the low advance ignition timing characteristic 41 when the use request detection means 11 has detected a deceleration request.SELECTED DRAWING: Figure 4 【課題】ユーザー要求に対する点火時期の応答性の向上を図る。【解決手段】点火時期特性に従ってエンジン回転数に応じて点火時期を制御するようにしたエンジン点火装置において、始動後の点火時期を制御する高進角点火時期特性４０と低進角点火時期特性４１とがあり、ユーザー要求を検出するユーザー要求検出手段１１と、ユーザー要求検出手段１１が加速要求を検出したときに低進角点火時期特性４１から高進角点火時期特性４０に切り替え、ユーザー要求検出手段１１が減速要求を検出したときに高進角点火時期特性４０から低進角点火時期特性４１に切り替える点火時期切り替え手段３５とを備える。【選択図】図４
