摘要： It is possible to suppress fluctuations of an air intake amount when the open degree of an air intake control valve is unknown. An engine includes an impulse valve common to all the cylinders arranged in the engine. The impulse valve is arranged in a communicating tube provided at the downstream side of a serge tank. An ECU executes impulse valve drive control. In the control, the ECU judges whether a rotation angle sensor which detects the open degree of the impulse valve has failed. If it is judged that the rotation angle sensor has failed, the ECU controls a drive motor and a drive circuit for driving a valve body so that a valve body of the impulse valve rotates inside the communicating tube. Here, the rotor of the drive motor which defines the rotation speed of the valve body has an rpm which is set in accordance with the mechanical rpm NE of the engine.

摘要： A multi-stage turbocharging system recovers exhaust energy that is conventionally lost in bypassing exhaust flow from one stage to another in a multi-stage turbocharging system. The exhaust energy is preserved through converting a portion of the exhaust energy of the bypassed flow from pressure to kinetic energy (velocity) by passing the bypassed flow through a VGT vane outlet or other variable geometry valve/nozzle, and then not allowing the accelerated flow to dissipate energy before reaching the subsequent stage's turbine wheel, where the accelerated flow may then be converted to a mechanical rotational force by the lower pressure turbine's wheel.

摘要： A fresh gas system for a piston engine has a collecting line for supplying fresh air to multiple individual lines. The fresh gas system has the collecting line which is unthrottled and a control unit for actuation of the additional valves is designed so that it subdivides a fresh gas charge of the combustion chamber which depends on the load state into two charging phases (A, B) within an intake time window (T). This is limited by the opening and closing of the intake valve such that it actuates the additional valve to close within the intake time window (T) at a closing point in (TS). This depends on the load state and then actuates it to open at a later opening point in time (TO) that depends on the load state of the piston engine.

摘要： The present invention relates to an operating method for a piston engine (1), in particular in a motor vehicle. The piston engine comprises a plurality of cylinders (6) having intake valves (9), exhaust valves (10), combustion chambers (7), and pistons (8); a fresh gas system (2) that contains an extra valve (13) assigned to the cylinders (6), a fuel system (5) and an exhaust system (4).To improve the smooth running of the piston engine (1), a fuel/fresh gas ratio in the exhaust gas is measured selectively for each cylinder in the exhaust system (4). The fuel system (5) is operated in such a way that it supplies the same amount of fuel to all combustion chambers (7) in steady-state operation of the piston engine (1). The extra valve (13) is operated in such a way that the quantity of fresh gas supplied to the combustion chambers (7) in steady-state operation is adjusted selectively for each cylinder as a function of the measured fuel/fresh gas ratio to achieve a target value for the fuel/fresh gas ratio that is the same for all cylinders (6).
