IPC: F02D41/14
Filed: 1992-09-11
Abstract: PURPOSE:To control air-fuel ratio adequately at the time of stopping feedback control based on the output of an air fuel ratio sensor located downstream so as to prevent supplied air fuel ratio from being shifted from its desired value by controlling the supplied air fuel ratio based on the first and second air fuel ratio compensating quantities. CONSTITUTION:An electronic control unit (ECU) 5 is installed, this ECU is provided with an air fuel ratio compensating quantity computing means, and air fuel ratio control means, an air fuel ratio compensating constant computation means and a memory means. Especially, the temperature, in a specific position of an internal combustion engine 1 is detected, and when the detected temperature is higher than the determined temperature, supplied air fuel ratio is controlled based on the first and second air-fuel ratio compensating quantities computed based on the outputs of air fuel ratio sensors 16, 17 located upstream and downstream are controlled. At the same time, the annealed value or average of the second air fuel ratio compensating quantity is computed and stored. When the detected temperature is lower than the determined temperature, the supplied air fuel ratio is controlled based on the annealed value or a verage of the first air fuel ratio compensating quantity and the stored second air fuel ratio compensating quantity.
