    摘要： A method of controlling an engine with a first group of cylinders having selectively deactivatable cylinders valves and a variable camshaft timing actuator coupled in a hydraulic system is described. In one example, the method includes during a first mode where the first group of cylinders is activated to carry out combustion cycles, adjusting the hydraulic system with a first gain based on cam timing feedback information and/or maintaining a null position of the actuator by adjusting a control signal to the hydraulic system to within a first value range. During a second mode where the first group of cylinders is deactivated, the method includes adjusting the hydraulic system with a second gain based on cam timing feedback information, the second gain higher than the first gain and/or maintaining the null position of the actuator by adjusting the control signal to the hydraulic system to within a second value range.

    摘要： Methods and systems are provided for monitoring cylinder valve deactivation in an engine operating with a plurality of cylinder valves. One example method comprises indicating valve degradation based on an indication of manifold pressure over a plurality of immediately successive induction events of the engine, the indication responsive to increases and decreases in the indication of manifold pressure correlated to the induction events of engine cylinders and further correlated to whether cylinders are commanded to be activated or deactivated.

    摘要： A system or method for controlling a multiple cylinder internal combustion engine operable in a reduced displacement mode with at least one valve or cylinder selectively deactivated include controlling the engine in response to detecting opening of an exhaust valve after deactivation based measured or inferred exhaust pressure changes after deactivation. In one embodiment, controlling the engine includes reactivating one or more deactivated cylinders/valves, inhibiting subsequent deactivation, and/or storing a diagnostic code in a computer readable storage medium in response to detecting valve opening after deactivation.

    摘要： Systems and methods are provided for operating an internal combustion engine including a variable cam timing (VCT) mechanism in cooperation with a plurality of deactivatable cylinders, each cylinder with a plurality of cylinder valves. One example method comprises, operating at a first cylinder valve timing before a transition of reactivating deactivated cylinders, and, before the transition, advancing cylinder valve timing from the first valve timing, where after the transition the cylinder valve timing remains at a second valve timing, the second valve timing advanced relative to the first valve timing.
