Title:
内燃機関の制御装置
Document Type and Number:
Japanese Patent JP3622290
Kind Code:
B2
Abstract:
When feedback control of air/fuel ratio is not being performed in an engine and the engine is idling, the fuel supply amount is increased according to the engine coolant temperature. When feedback control of air/fuel ratio is not being performed and the engine is not idling, the fuel supply amount is decreased according to the engine coolant temperature. Due to this decrease correction, during the time period from when idling operation is terminated directly after starting the engine to when the feedback control of the air/fuel ratio is started, the air/fuel ratio is made lean at an early stage, and the oxygen concentration in the engine exhaust gas is increased, so that the conversion of HC by the catalyst is quickly started.
