Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 内燃機関の目標空燃比の周波数と振幅を故意 にリッチ側からリーン側に変化させてキャタライザの浄 化率を向上させるパータベーション制御に関する装置で あって、所定の周波数と振幅を持った目標空燃比を周期 関数で設定しておき、機関のTDC周期に基礎をおく値 で離散化して空燃比を制御する。 【効果】 機関回転数や機関負荷の変動にかかわらず、 目標空燃比を所定の周波数と振幅に制御することができ る。 (57) [Summary] [Structure] A device for perturbation control that intentionally changes the frequency and amplitude of the target air-fuel ratio of an internal combustion engine from the rich side to the lean side to improve the purification rate of the catalyzer. The target air-fuel ratio having the amplitude is set by a periodic function, and the air-fuel ratio is controlled by discretizing the value based on the TDC cycle of the engine. [Effect] Regardless of changes in engine speed and engine load, The target air-fuel ratio can be controlled to a predetermined frequency and amplitude.
