    Abstract: In cases where an EGR device is provided in which an EGR gas is recirculated to an upstream side of a compressor, the generation of condensed water is suppressed in an intake passage at the downstream side of the compressor. In the case where the temperature of a wall surface of the intake passage estimated or detected by a temperature detector is equal to or less than a predetermined temperature, a rotational speed of a turbine is made higher than in the case where the estimated or detected temperature of the wall surface of the intake passage is higher than the predetermined temperature, and torque of an internal combustion engine is adjusted such that an amount of change in an output of the internal combustion engine at the time of the rotational speed of the turbine being thus made higher falls within a predetermined range.

    Abstract: A supercharged internal combustion engine has a supercharger operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine. The supercharger has a shuttle combined with a throttle valve that controls the mass of air directed to an air mass bypass opening and supplied to the internal combustion engine. The shuttle has rollers that ride on rails that allow the shuttle to move to open and close the air mass bypass opening in communication with a casing that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet of the supercharger.

    Abstract: A method of and apparatus for operating a supercharger for an automotive engine is disclosed. The supercharger has: an input shaft for coupling to an engine crankshaft, and coupled to the rotor of a first electrical machine and a first component of an epicyclic gear train; and an output shaft connected to a compressor and a second component of the epicyclic gear train; wherein the third component of the epicyclic gear train is connected to the rotor of a second electrical machine. The first electrical machine is selectively operable to supply electrical energy to the second electrical machine. The method includes the steps of: (a) calculating a required speed of the second electrical machine that would give rise to a required pressure at an outlet of the compressor; and (b) setting the speed of the second electrical machine to the calculated required speed.
