摘要： In a variable valve timing apparatus having a VVT mechanism in each of a plurality of banks, start of a valve timing control is not permitted (S190) until reference position learning of valve timing is completed (S170, S180) in the corresponding bank and in other banks. Accordingly, the plurality of banks come to have matching valve timing setting at the time of valve timing control, whereby variation in the amount of air introduced to cylinders can be suppressed, and satisfactory combustion characteristics can be maintained.

摘要： A control device for an internal combustion engine includes an intake-side variable valve timing mechanism and a controller. The intake-side variable valve timing mechanism is configured to continuously advance or retard a phase of a cam that actuates an intake valve. The controller is configured to actuate the intake-side variable valve timing mechanism toward a retardation side and position the intake-side variable valve timing mechanism at a prescribed position, and execute fail-safe control on the basis of a signal from a cam position sensor instead of a signal from the crank position sensor, when it is determined that there is a failure in a crank position sensor of the internal combustion engine.

摘要： In valve timing control after issuance of an engine stop instruction (YES at S100) with a prescribed value (CA#) set as a target phase (S110), an ECU delays permission of an engine stop process (S130) within a prescribed time period (NO at step S140) while an intake valve phase (IV(q)) has not yet reached the target value (CA#) (NO at S120), so that a valve timing control operation is continued (S150) while the engine operation is continued in an idle state. After the lapse of a prescribed time period from the issuance of the engine stop instruction (YES at S140), however, the ECU permits the engine stop process (S130) no matter whether the intake valve phase has reached the target value (CA#) or not. As a result, the amount of valve timing that can be changed by the valve timing control in the engine stop operation can be increased, without causing any uncomfortable feeling of the driver.
摘要翻译：在发出发动机停止指令（S100中为“是”）且规定值（CA＃）被设定为目标相位（S110）之后的气门正时控制中，ECU延迟发动机停止过程（S130）的许可在规定时间段（步骤S140中为“否”），并且进气门相位（IV（q））尚未达到目标值（CA＃）（S120中的“否”），从而在发动机运转时继续气门正时控制操作（S150）继续处于空闲状态。然而，在发出发动机停止指令经过规定的时间段之后（S140中为“是”），无论进气门相位是否达到目标值（CA＃），ECU都允许发动机停止过程（S130）或不。结果，可以增加在发动机停止操作中通过气门正时控制可以改变的气门正时量，而不会引起驾驶员不舒服的感觉。
