Title: Air-fuel ratio controller for internal combustion engine
Inventor: MIYASHITA KOTARO
IPC: F02D41/02
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To provide an air-fuel ratio controller for internal combustion engine, which can maintain stable air-fuel ratio feedback control even in case disturbance such as the influence of evaporation purging occurs. SOLUTION: The fuel jetting time Tout of a fuel jet valve has an expression: (air-fuel ratio correction coefficient KLAF) ×(evaporation correction coefficient KEVAP). When the fuel jetting time Tout is corrected by the air-fuel ratio correction coefficient KLAF obtained by multiplying a difference between a targeted air-fuel ratio coefficient KCMD and a detected air-fuel ratio KACT by a feedback gain. When the evaporation correction coefficient KEVAP is small and the influence of purging is large, the changing ratio of the air-fuel ratio correction coefficient KLAF is reduced (S203). It is thus possible to prevent hunting occurrence in feedback.
