Document Type and Number:
WIPO Patent Application WO/2013/115174
Kind Code:
A1
Abstract:
In the present invention, when a crank angle sensor (12) failure is detected, thereafter, the valve aperture of a throttle valve (9) is corrected in the direction of valve closing, and engine rotational velocity limiting is executed in a manner so that the engine rotational velocity is no greater than predetermined upper limit rotational velocity. Also, a variable valve timing mechanism (2) is controlled in a manner so that the valve timing of an intake valve (1) is at a predetermined intermediate position and the variable valve timing mechanism (2) is locked at the predetermined intermediate position by means of a locking mechanism (34).
