    Abstract: An object of the present invention is to provide a control device for a turbocharged engine capable of accurately estimating the revolution speed of a turbine without using additional components for directly detecting the turbine revolution speed, and by accurately estimating the turbine revolution speed, capable of accurately keeping the turbine revolution speed at an allowed value or below and preventing excessive rotation. The control device for a turbocharged engine includes a turbocharger having a compressor disposed in an intake passage of an engine, and a turbine disposed in an exhaust passage of the engine, a fuel injection amount control unit for controlling a fuel injection amount to the engine according to an operating state of the engine, and a turbine revolution speed estimation unit for determining by calculations an estimated value of a revolution speed of the turbine from the operating state of the engine. When the estimated value of the turbine revolution speed exceeds a predetermined allowed value, the fuel injection control unit controls the fuel injection amount such that the estimated value of the turbine revolution speed becomes equal to or less than the allowed value.

    Abstract: Systems for preventing/controlling compressor surge in an electrically assisted turbocharger comprise a turbocharger (10) having an electric motor (18) disposed around a turbocharger shaft (22). The electric motor controller (30) is electrically coupled to the electric motor (18) for controlling the rotational movement provided by the electric motor (18) to the turbocharger shaft (22). A memory is electrically coupled to the electric motor controller (30) and comprises a mufti-dimensional map of compressor surge conditions stored therein. Sensors (32) are used to provide desired engine and/or turbocharger operating information for comparing against the stored map data. The sensors (32) are electrically coupled to the electric motor controller (30). The controller plots the actual operating information provided by the sensors (32) on the stored map to evaluate whether the turbocharger is operating in different operating regions. If the plotted turbocharger operation falls within a surge risk or surge state operating region, the motor controller operates the electric motor (18) in a manner that reduces the rotational speed of the turbocharger shaft.

    Abstract: It is an object to provide an engine that makes it possible to constantly detect the number of rotations of a supercharger with a calculation load of an ECU reduced. An engine 1 is provided with an engine base 8 comprised of a plurality of cylinders and a turbocharger 7, a crank angle sensor 4, a turbo sensor 5 that detects rotations of the turbocharger 7 as pulses, an amplifier 11 that divides the pulses by an arbitrary division ratio and calculates the divided pulses, and an ECU 10 that judges a surge condition of the turbocharger 7, wherein the ECU 10 sets a predetermined position of a piston of each cylinder in a crank angle of the engine base 8 to count start timing of the divided pulses, outputs the divided pulses counted from the count start timing to the number of predetermined rotations as a first output, and judges that, if a difference between the first outputs at every cylinder is more than a predetermined value, the turbocharger 7 is in the surge condition.

    Abstract: A variable flow valve assembly is disclosed, and includes a main body and a piston. The main body defines a chamber, an inlet port, an outlet port, and a wall located between the inlet port and the outlet port. The wall defines a metering orifice for selectively allowing a medium to flow from the inlet port to the outlet port. The piston is moveable within the chamber of the main body in a plurality of partially open positions to vary the amount of medium flowing through the modulation orifice.
