  • Patent number: 7289901
    Abstract: A vehicle-mounted power generator set including: an AC generator driven by an engine of a vehicle; an electric power conversion portion that converts an output of the AC generator into an AC output having commercial frequency; a controller having electric power conversion portion control means for controlling the conversion portion to generate an AC output having commercial frequency when a control mode is a power generation mode, and engine control means for controlling the engine to rotate at a rotational speed suitable for supplying electric power from the conversion portion to a load when the control mode is the power generation mode and controlling the engine to be suitable for driving the vehicle when the control mode is the vehicle driving mode; and a control switch inserted between each output terminal of the AC generator and each input terminal of the electric power conversion portion, and controlled to be in an ON state when the control mode is the power generation mode and in an OFF state when the

  • Patent number: 7267099
    Abstract: A multicylinder engine intake system includes: first and second throttle bodies; bypasses provided in the first and second throttle bodies and having downstream ends opened to intake paths on downstream sides of throttle valves; and a common bypass control valve which opens and closes the bypasses. The bypass control valve is mounted on the first throttle body. Downstream ends of the bypasses opened in the first and second throttle bodies are formed as throttle holes. The diameter of the throttle hole on the side of the first throttle body is smaller than the diameter of the throttle hole on the second throttle body. Thus, it is possible to equalize amounts of first idling air supplied to a plurality of cylinders irrespective of arrangement of the cylinders in an engine even if lengths of a plurality of bypass downstream paths are not equal to each other, while the bypass control valve is mounted on any of the throttle bodies.

  • Patent number: 7260470
    Abstract: A method for calibrating at least two sensors for sensing a variable characterizing the combustion process in an internal combustion engine of a motor vehicle, operated in individual-cylinder fashion and having at least two cylinders, is provided. According to the present invention, at least one operating point of the internal combustion engine, at which an equalization of the at least two cylinders by at least one fuel quantity equalization method is performable with high accuracy, is determined. At the at least one operating point of the internal combustion engine, an equalization of the at least two cylinders is performed by the at least one fuel quantity equalization method. After the equalization of the at least two cylinders has been accomplished, at least one sensor parameter of the at least two sensors is mutually adjusted.
