A fail-safe processing method for an internal combustion engine including: carrying out a failure diagnosis for determining whether a failure of an electronic-controlled intake device occurs; determining whether a mode of the failure of the electronic-controlled intake device is a vehicle accelerating mode when it is determined that the failure occurs; carrying out a fail-safe processing when it is determined that the failure mode is the vehicle accelerating mode, wherein the fail-safe processing determines an optimal value of the valve-lift amount; and controlling a variable valve-lift mechanism in accordance with the optimal value of the valve-lift amount <IMAGE> |
