Title: Air-fuel ratio control device for internal combustion engine
Inventor: YOSHINO HIROYASU
IPC: F02D41/14
Filed: 1994-12-27
Abstract: PURPOSE: To obtain an appropriate HC/NOx ratio at all times so as to improve exhaust emission purifying performance using purge gas as much as possible by setting a target air-fuel ratio at the time of lean air-fuel ratio control on the basis of an engine operating state and purge gas concentration detected at the time of desorbing treatment of evaporated fuel. CONSTITUTION: After adsorbing evaporated fuel, generated in a fuel tank 12, by a canister 14, this evaporated fuel is desorbed and supplied as purge gas to an intake system through a purge control valve 15. At this time, the air-fuel ratio of mixture actually sucked into an engine is controlled by a control unit 50 so as to become a target air-fuel ratio leaner than a stoichiometric air-fuel ratio. In such a device, the concentration of purge gas is estimated on the basis of the learning value at the end time of air-fuel ratio feedback control immediately before the start of lean air-fuel ratio control and the accumulation of purge gas flow after the start of lean air-fuel ratio control. A target air-fuel ratio at the time of performing lean air-fuel ratio control is set on the basis of the purge gas concentration and the operating state detection value.
