Specific Throttle Valve Structure Patents (Class 123/337)
  • Patent number: 11092091
    Abstract: Embodiments of a gaseous or dual fuel electronic pressure regulation system (EPRS) for a multipoint fuel injection engine are described herein. Additionally, embodiments of a method for controlling the EPRS are provided. In particular, the EPRS employs an electronic pressure regulator (EPR) capable of accurately determining and controlling the mass flow of gaseous fuel into a fuel rail so as to avoid pressure droop and over- and under-pressurization of the gas admission valves (GAVs). By using the EPRS described above, mass flow is able to be distributed to the downstream manifold or engine cylinders very accurately, and the GAVs are able to be driven simultaneously in a pressure/pulse duration that is optimal for accurate and repeatable operation.

  • Publication number: 20150114343
    Abstract: A method of operating a vehicle having an engine, an engine control unit (ECU), a throttle operator, and a throttle body fluidly communicating with the engine. A throttle valve disposed in the throttle body regulates fluid flow to the engine. A throttle valve actuator is connected thereto for controlling a throttle valve position. A key receiver is configured to link to a key. The method includes linking a key to the key receiver and initiating engine operation. If the key is linked to the key receiver and engine operation has been initiated, an identification code of the key is read and an authorization status of the key is thereby determined. If the key is determined to be authorized, the throttle valve position is controlled based in part on a throttle operator position. If the key is determined to be unauthorized, the throttle valve position is limited to a security limit.

  • Patent number: 8997713
    Abstract: A vehicular air intake is configured to produce a turbulent intake air flow in a cylinder of an engine. The air flow may be provided as a vortex. A throttle valve, for controlling an amount of intake air provided to the engine, has a pivot shaft with an axis which is offset from a center axis of an air intake passage in which the throttle valve is installed, and a throttle plate affixed to the pivot shaft. The pivot axis is offset and spaced away from the central axis of the throttle body such that a first portion of a throttle plate disposed on a first side of the pivot shaft, is larger than a second portion of the throttle plate disposed on a second side of the pivot shaft. This arrangement provides the non-uniform turbulent air flow into the engine.

  • Patent number: 8978622
    Abstract: There is provided an automatic choke apparatus for an engine. A bimetal that is coupled to a choke valve of an intake system is provided in the vicinity of an outer wall face of a muffler. The muffler is divided into a first expansion chamber and a second expansion chamber across a partition plate. An exhaust hole that allows the expansion chambers to be communicated with each other is formed at the lower part of the partition plate. An exhaust gas is guided from the upstream first expansion chamber toward the downstream second expansion chamber through the exhaust hole. A bypass hole is formed at an upper part of the partition plate in such a manner that that the expansion chambers are communicated with each other as bypassing the exhaust hole. The bypass hole is open to the vicinity of the outer wall face opposite to the bimetal.

  • Patent number: 8973555
    Abstract: An air-intake control apparatus of an internal combustion engine formed by attaching a flange portion provided to an end portion of a drive motor to a cylindrical hole portion. A throttle body has at least one positioning projection (or recess) provided to an inner wall of the cylindrical hole portion. The drive motor complementarily has at least one positioning recess (or projection) provided to the flange portion at a position corresponding to the positioning projection (or recess). The drive motor is attached to the cylindrical hole portion while the positioning recess (or projection) abuts on the positioning projection (or recess) in such a manner that a center distance between a motor shaft and a throttle shaft takes a predetermined value. Hence, not only attachment workability but also attachment accuracy of the drive motor can be enhanced. The air-intake control device therefore has higher product reliability.

  • Publication number: 20150040860
    Abstract: A butterfly bypass valve includes a housing defining a bypass flow passage with a pivotable throttle plate therein. An outer edge of the throttle plate in a closed position is in sealing engagement with a sealing portion of the housing such that the throttle plate restricts fluid flow through the bypass flow passage. The throttle plate is pivotable to an open position to allow fluid flow through the bypass flow passage. A port in the housing allows a portion of fluid passing through the bypass flow passage to be removed when the throttle plate is pivoted to the open position. A predetermined amount of pivoting of the throttle plate toward the open position can occur so as to allow flow through the port, while maintaining the edge of the throttle plate in substantially sealing engagement with the sealing portion so as to substantially prevent flow through the bypass passage.

  • Patent number: 8905009
    Abstract: When a failure occurs in synchronizing mechanism, an intake air throttle valve is rotated in a direction that is opposite from a normal operational time valve closing direction, so that an arm of a driven plate contacts a throttle valve side stopper to stop rotation of the intake air throttle valve. Thereafter, when a low pressure EGR valve is rotated from a full close position to a full open position, an EGR valve side stopper contacts the arm of the driven plate to stop the low pressure EGR valve. A rotational angle of the EGR valve is sensed with a sensor and is outputted to an ECU. The ECU determines that a failure mode is set when a valve angle sensed with the sensor coincides with a rotation stop position of the EGR valve.
