摘要： To prevent an increase in torque when the fixed state of a throttle valve is released. When diagnostics reads fixed diagnostics flag 1 indicating that the throttle valve is in a fixed state, control value ATVO that can maintain throttle aperture RTVO is set (S 11, S 12) based on. detected value RTVO for the throttle aperture in the current fixed state, fuel injection volume TiO that is calculated according to new air volume Q is secured at fuel injection volume TiL or greater in order to achieve the engine torque for when fail-safe control is executed, and when air-fuel ratio),is less than the lower limit valueXL, causing an increase in the amount of smoke, control is executed to suppress the occurrence of said smoke.
