摘要： In starting the engine, if it is determined that large cams are not completely prepared for all driving cams, valve closing timings of all intake valves are changed by driving the VVT so that all of the cylinders have equal in-cylinder filling efficiency. A fuel injection amount of each cylinder is determined by a feedforward control assuming that the large cams are completely prepared for all of the driving cams. When the valve closing timing of all of the intake valves are changed by driving the VVT to equalize the in-cylinder filling efficiencies of all of the cylinders, all of the cylinders have substantially equal in-cylinder air-fuel ratios.

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： A method for operating an internal combustion engine in the event of a fault in a crankshaft sensor is provided, the internal combustion engine having at least two camshafts and a speed and/or a position of the internal combustion engine being derived from a signal taken from the camshaft. In order to improve the exhaust gas performance of the internal combustion engine even in a crankshaft emergency operating mode, only a first camshaft is used to determine the speed and/or the position of the internal combustion engine, while the second camshaft. is adjusted in its angle of rotation in order to set a variable valve operating mechanism on the intake and exhaust valves of the internal combustion engine that are driven by the second camshaft.

摘要： A valve timing adjusting apparatus includes a housing, a vane rotor, and a fluid path arrangement. The fluid path arrangement is provided inside the housing. The fluid path arrangement opens to air outside the housing. The fluid path arrangement is communicated with a specific fluid chamber that is one of an advance fluid chamber and a retard fluid chamber defined within the housing. A rotational phase of the vane rotor relative to the housing is changed in one of advance and retard directions when hydraulic oil is introduced into the specific fluid chamber. The valve timing adjusting apparatus controls the fluid path arrangement to be opened and closed.

摘要： A method for detecting a low-lift or zero-lift failure mode in a variable valve activation system of an internal combustion engine includes the steps of positioning a piezo-electric element that acts as a radio frequency transmitter relative to a lost motion spring of a two-mode variable valve activation lost motion device, subjecting the piezo-electric element to a compression load when a load from displacement of a lobe of a camshaft acts on the lost motion spring, broadcasting a radio frequency signal each time the piezo-electric element is subjected to the compression load, and evaluating the presence or absence of the broadcasted radio frequency signal in relation to an expected presence or absence of the radio frequency signal. The direct measurement of the mode of each two-mode device is both more reliable and more efficient in the use of engine controller resources compared to currently existing diagnostic methods.

摘要： When the engine speed is high (determination of YES at S100), actual intake valve phase is calculated based on rotation phase difference between rotation angles of crankshaft and camshaft, detected by using a crank angle signal and a cam angle signal, and actual valve timing is detected therefrom. When the engine speed is low (determination of NO at S100) and the crank angle signal and cam angle signal are unstable, an amount of change in camshaft rotation phase by the VVT mechanism in accordance with the operation amount of actuator detected by a motor rotation angle signal is calculated successively, and based on an accumulation of the amount of change, the actual intake valve phase is calculated, and the actual valve timing is detected.

摘要： A valve timing system for an internal combustion engine includes a phase alteration mechanism interposed between a driving rotator and a driven rotator and having a direction turning point at which the phase alteration direction is reversed when a movable portion of the mechanism travels from a beginning to a termination, and an operation control device for displacing the movable portion when undergoing an energization control, the movable portion being displaced toward the beginning when the energization control fails to be carried out. The rotation phase is set at a middle position between a maximum retard position and a maximum advance position when the movable portion is located at the beginning.
