  • Patent number: 10006311
    Abstract: A method of recovering waste heat includes pressurizing a flow of working fluid and transferring heat from a hot gas stream to the flow of working fluid in at least two successively arranged heat transfer sections. At least some of the working fluid is converted to a superheated vapor by the transfer of heat, and passes through an expander to recover useful work. A portion of the flow of working fluid is directed along a branch after having passed through at least one of the heat transfer sections, and bypasses the expander and at least one of the heat transfer sections before being recombined with the working fluid that has passed through the expander. The total flow rate of working fluid can be adjusted to regulate the temperature of the hot gas stream downstream of the heat transfer sections, and the amount of fluid that bypasses along the branch can be adjusted to regulate the temperature of the superheated vapor.

    Abstract: The objective of the present invention is to provide a controller for a supercharger-equipped internal combustion engine and a control method that can reduce man-hours for data measurement and matching, which are required to perform while the internal combustion engine and the supercharger are combined. In a controller, a target turbine flow rate for realizing a target compressor driving force is calculated; a target wastegate flow rate is calculated based on an exhaust gas flow rate and the target turbine flow rate; a target turbine-upstream pressure is calculated based on a target before/after-turbine pressure ratio for realizing the target compressor driving force and a turbine-downstream pressure; a target gate effective opening area is calculated based on the target wastegate flow rate, the target before/after-turbine pressure ratio, and the target turbine-upstream pressure; then, a gate valve control value is calculated.

  • Patent number: 9957883
    Abstract: A controller, for a supercharger-equipped internal combustion engine, that can improve the feedback response of compressor driving force is provided. In a controller, inertial force produced by an inertial moment of a supercharger is calculated, based on a real rotation speed of the supercharger; then, driving force feedback control is implemented in which a gate valve control value, which is a control value for a gate valve actuator, is changed so that an addition value obtained by adding the inertial force to the real compressor driving force approaches a target compressor driving force.
