Ignition timing control device of internal combustion engine
Abstract
Abstract Translated from Japanese (57)【要約】 【目的】 機関の運転性をできるだけ損なうことなく、 触媒を早期に活性化するように点火時期を制御する。 【構成】 運転条件から基本点火時期を算出する手段2 と、運転条件あるいは触媒温度から点火時期の遅角補正 領域を判定する手段3と、遅角補正領域にあるときに運 転条件あるいは触媒温度に応じて基本遅角量を算出する 手段4と、アクセル開度または絞弁開度に応じて前記基 本遅角量の補正値を算出する手段6と、この補正値に基 づいて前記基本遅角量を補正する遅角量補正手段7と、 補正された遅角量をもとに前記基本点火時期を修正する 手段8とを備える。 (57) [Summary] [Purpose] Without impairing the drivability of the engine as much as possible, The ignition timing is controlled so as to activate the catalyst early. [Configuration] Means 2 for calculating a basic ignition timing from operating conditions A means 3 for determining the ignition timing retarding correction region from the operating condition or the catalyst temperature; a means 4 for calculating a basic retarding amount according to the operating condition or the catalyst temperature when in the retarding angle correction region; and an accelerator. A means 6 for calculating a correction value of the basic retardation amount according to the opening degree or the throttle opening degree, and a retardation amount correction means 7 for correcting the basic retardation amount based on the correction value. And means 8 for correcting the basic ignition timing based on the corrected retard amount.
