摘要： An abnormality diagnosis system of an internal combustion engine that is installed on a vehicle and includes an actuator includes an electronic control unit. The electronic control unit receives vehicle outside information concerning a period of time for which the vehicle speed is less than a predetermined value, and determines whether the period for which the vehicle speed is less than the predetermined value is expected to be equal to or longer than a length of time required for an abnormality diagnosis of an abnormality diagnosis target device. The electronic control unit activates the actuator and starts the abnormality diagnosis as the vehicle speed becomes lower than the predetermined value, when it determines that the period for which the vehicle speed is lower than the predetermined value is expected to be equal to or longer than the time required for the abnormality diagnosis of the target device.

摘要： Disclosed is a method of manufacturing a sliding cam assembly. In particular, a requirement for wear resistance of a hollow tubular portion in which sliding takes place can be satisfied due to a cam piece being fixed to the hollow tubular portion by diffusion bonding while the sliding cam assembly repeatedly slides along a shaft, and each component can be separately machined and combined, thus minimizing an amount which is wasted at the time of machining, reducing the machining time, and rendering a separate heat treatment of a cam piece unnecessary.

摘要： Methods and systems are described for an engine with a cam torque actuated variable cam timing phaser. Phaser positioning control is improved by reducing inaccuracies resulting from inadvertent spool valve and/or phaser movement when the spool valve is commanded between regions. In addition, improved spool valve mapping is used to render phaser commands more consistent and robust.

摘要： A method is provided for controlling a filling (rl) of an internal combustion engine (2) including the camshaft phase adjustment in the case of a predefined setpoint filling (rlsol), including the following steps: carrying out the filling control based on an indicated pressure difference for obtaining a control variable (ΛFuereg) for setting an air mass supply to the internal combustion engine (2); and ascertaining the indicated pressure difference (ΔpSR) as a difference between a predicted intake manifold pressure (psrpred) and an actual intake manifold pressure (pSR), the predicted intake manifold pressure (psrpred) corresponding to an intake manifold pressure which is necessary for reaching the setpoint filling (rlsol) at an aspiration curve which is predicted for a predefined time constant (τ).

摘要： A system according to the principles of the present disclosure includes a valve lift determination module and a fault detection module. The valve lift determination module determines valve lift based on at least one of a first period when a valve is open and N differences between a first value of a valve lift signal generated by a valve lift sensor when the valve is closed and a second value of the valve lift signal when the valve is open, wherein N is an integer greater than one. The fault detection module detects a fault in a valve actuator based on the valve lift.

摘要： A pneumatic engine system uses gas circulation to recycle exhausted air, so as to reduce gas consumption, save energy, protect the environment, operate for a longer duration, and slow down the attenuation of the power output thereof. The pneumatic engine system includes a pneumatic engine, a gas storage device, a transit gas storage tank, and a suction device. The pneumatic engine receives a compressed air to generate power output. The gas storage device stores the compressed gas and supplies the compressed gas to the pneumatic engine. The transit gas storage tank receives gas discharged from the pneumatic engine. The suction device extracts gas from the transit gas storage tank and transport the extracted gas to the gas storage device for recycle.

摘要： A multi-cylinder internal combustion engine is provided with a system for the variable actuation of the intake valves, and such system is used to vary the amount of air taken in by each cylinder so as to reduce to the minimum or entirely eliminate the differences in the torque produced by the various cylinders and hence limit the irregularities in the rotation speed of the engine shaft.

摘要： An engine assembly includes an engine block having a first bank of cylinders and a second bank of cylinders. A crankshaft is supported by the engine block and is configured to be driven by torque due to combustion energy in the first and second banks of cylinders. A first set of valves is operable to control air flow into and out of the first bank of cylinders. Camshafts driven by the crankshaft are operatively connected to the first set of valves to control opening and closing of the first set of valves. A second set of valves is operable to control air flow into and out of the second bank of cylinders. A controller is operatively connected to the second set of valves and is configured to vary at least one of lift, duration, and timing of the second set of valves based on commanded torque at the crankshaft.
