Document Type and Number:
Japanese Patent JP5821865
Kind Code:
B2
Abstract:
An MBT ignition time and a knock ignition time are acquired from an engine rotation speed and engine load, and an ignition time on a delay angle side, out of these ignition times, is set as the most advance angle ignition time. An ignition time on the delay angle side only by the KCS learning value with respect to the most advance angle ignition time is set as a required ignition time, and when an actual ignition time set by a knock control system exceeds a predetermined amount and is positioned on the delay angle side with respect to the required ignition time, it is determined that abnormality occurs in an oil jet. Fail-safe processing to the effect that the opening degrees of a throttle valve are corrected to a closed side is executed in response to the abnormality determination.
