  • Patent number: 9422855
    Abstract: Methods and systems are provided for removing condensate from an intercooler of a turbocharged internal combustion engine. Using valves to drain condensate may create a direct fluidic connection between the compressed air of the intercooler and ambient exterior air, allowing both condensate and compressed air to escape due to valve design or failure of valve actuation devices. To provide a simple and reliable method for removing condensate without removing compressed air, a hollow valve is used to shuttle condensate from the intercooler to the exterior environment.

  • Patent number: 9422858
    Abstract: A turbocharger includes an annular bypass passage with an annular bypass valve disposed therein. The bypass valve includes a fixed annular valve seat and a rotary annular valve member disposed against the valve seat. The valve member is rotatable about the axis for varying a degree of alignment between orifices in the valve seat and valve member so as to form flow passages having a flow area A for exhaust gas. The orifices are shaped to provide a first phase of evolution of the flow area A from zero up to a value A1 and then a second phase of evolution from the value A1 up to a value A2, and such that the first and second phases have distinctly different slopes on a curve of flow area versus rotational position of the valve member, with a distinct break point in the curve between the first and second phases.

  • Patent number: 9334833
    Abstract: A turbocharger system for ensuring a sufficient exhaust gas recirculation (“EGR”) amount in all operating conditions, and reducing NOx emission from an engine. The system includes an EGR controller that re-circulates a part of exhaust gas discharged from the engine to an intake side. The turbocharger is a power-assisted turbocharger including an electric motor that assists a drive force of a compressor. The EGR controller controls an amount of exhaust gas recirculated to the intake side so as to inhibit the generation of NOx regardless of an amount of oxygen necessary for combustion of the engine. An electric motor control unit drives the electric motor, by the control of the EGR controller, when the amount of oxygen necessary for the combustion of the engine is deficient.

  • Patent number: 9273593
    Abstract: An ECU alternatively changes a target air-fuel ratio At to a rich side and a lean side by active air-fuel ratio control. The ECU measures an oxygen storage capacity OSC of an exhaust purification catalyst based on an oscillation period of the target air-fuel ratio At and the target aft-fuel ratio At, and executes a deterioration determination with respect to the exhaust purification catalyst based on the measurement value. When executing the deterioration determination, the ECU closes a waste gate valve to prevent a decrease in the accuracy of the deterioration determination that is caused by two kinds of exhaust gas whose flow paths are different from each other arriving at the area surrounding an air-fuel ratio sensor.

  • Patent number: 9249722
    Abstract: The present invention relates to a system for improving the performance of a rotary engine comprising at least one of a piston having at least one piston vane configured to rotate. A peddle block is positioned in the pathway of the piston vane, wherein as the piston vane approaches the peddle block a secondary exhaust pressure increases against the piston vane surface, the secondary exhaust pressure, in part, causes the piston vane to rotate and self-align for a subsequent cycle. A variable orifice secondary exhaust port selectively vents at least a portion of the secondary exhaust pressure, away from the piston vane setting an optimal rotational speed of the piston vane, improving performance of the rotary engine. Other exemplary embodiments include turbo-charging the rotary engine by increasing the secondary exhaust pressure, increasing the piston vane rotation, and increasing the amount of secondary exhaust pressure that is recirculated.
