Definitions

  • the present invention relates to a fuel feeding mechanism of a vehicle, more particularly one, whose throttle position sensor is equipped with a signal source to interfere in and change a signal of the throttle so as to help to advance the time of the vehicle shifting gears and reduce fuel consumption.
  • a kind of currently existing vehicle fuel-feeding mechanism includes an electronic control unit, and a throttle.
  • the throttle comprises a pivotal shaft, and a valve pivoted on the pivotal shaft, and is equipped with a feedback signal device.
  • the feedback signal device is connected with the electronic control unit.
  • a throttle position sensor is connected with the pivotal shaft of the throttle, which sensor is equipped with a variable resistor capable of changing in resistance in rotation.
  • the inventor of the present invention has been devoting much time and effort to developing a vehicle fuel-feeding mechanism, which can advance the time of the vehicle shifting gears, and help to reduce fuel consumption, and which is suitable for use with vehicles of any model without the need for re-equipping the engine.
  • a fuel feeding mechanism includes an electronic control unit, and a throttle.
  • the throttle includes a pivotal shaft and a valve pivoted on the pivotal shaft, and is connected with a feedback signal device.
  • the feedback signal device is connected to the electronic control unit.
  • a throttle position sensor is connected to the pivotal shaft of the throttle; the throttle position sensor includes a variable resistor, which will change in resistance on rotation, and which is connected with a signal source.
  • the signal source is connected with the feedback signal device of the throttle so as to interfere in and change a signal of the throttle, thus helping to advance the time of the vehicle shifting gears and reduce consumption of fuel.
  • a first preferred embodiment of a fuel feeding mechanism of a vehicle in the present invention includes an electronic control unit (ECU) 1, a throttle 2, and a throttle position sensor (TPS) 3.
  • ECU electronice control unit
  • TPS throttle position sensor
  • the electronic control unit 1 is used to control operation of an engine of a vehicle in order for allowing an optimum amount of fuel to be injected, and ignition to take place at an optimum time.
  • the throttle 2 is a valve of a butterfly-shaped type. Referring to Fig. 3 as well, the throttle 2 comprises a pivotal shaft 21, and a valve 22 pivoted on the pivotal shaft 21. Furthermore, the throttle 2 is connected to a feedback signal device 23.
  • the throttle position sensor 3 includes a variable resistor 31, which will change in its resistance when being rotated.
  • the throttle position sensor 3 includes a signal source 32, which is connected to the variable resistor 31.
  • the throttle position sensor 3 further includes adjustment buttons 33 for a start of the throttle position sensor 3, adjustment buttons 34 for stoppage of the throttle position sensor 3, and indicating lamps 35.
  • the adjustment buttons 33 for start are used to set a floor value of a rotational speed of the engine; the throttle position sensor 3 will be activated, and a stable voltage will be transmitted to the electronic control unit 1 as soon as the rotational speed of the engine reaches the floor value.
  • the adjustment buttons 34 for stoppage are used to set a ceiling value of a rotational speed of the engine; the throttle position sensor 3 will be turned off, and a stable voltage will be transmitted to the electronic control unit 1 as soon as the rotational speed of the engine reaches the ceiling value.
  • the indicating lamps 35 are used to show a current set value of rotational speed of the engine in the above setting.
  • the feedback signal device 23 of the throttle 2 is connected to the electronic control unit 1; thus, a signal of the valve 22 opening is feedback to the electronic control unit 1 in order for the electronic control unit 1 to make the engine to run on an optimum amount of fuel injection.
  • the variable resistor 31 of the throttle position sensor 3 is installed on the pivotal shaft 21 of the throttle 2 so as to change in its resistance in rotational motion of the pivotal shaft 21.
  • the signal source 32 of the throttle position sensor 3 is connected to feedback signal device 23 of the throttle 2; the signal source 32 is used to transmit a signal to the electronic control unit 1, which is slightly smaller than the signal feedback from the throttle 2 to the electronic control unit 1, so as to interfere in and change the signal of the throttle 2; thus, the time of the vehicle shifting gears is advanced.
  • the rotational speed of the vehicle engine is 2500RPM/ 60KM originally, and will become 2200RPM/ 60KM after the signal is changed.
  • the driver uses the adjustment buttons 33 to set a floor value of rotational speed of the engine, and uses the adjustment buttons 34 to set a ceiling value of rotational speed of the engine according to the model and the exhaust amount of the vehicle. Therefore, in the course of the vehicle shifting gears, the rotational speed of the engine will be in the range of the floor value to the ceiling value.
  • the throttle position sensor 3 will send a stable voltage feedback to the electronic control unit 1, and in turn the electronic control unit 1 will control the fuel injector so as not to inject additional fuel in gear-shifting of the vehicle, thus helping to save fuel; conventionally, engines will consume more fuel in gear-shifting of vehicles.
  • the second preferred embodiment is basically the same as the first one, yet it further includes an accelerator pedal position sensor (APS) 4, which is connected to the electronic control unit 1.
  • APS accelerator pedal position sensor
  • the accelerator pedal position sensor 4 will sense motion of the accelerator pedal of the vehicle, and the distance value that the accelerator pedal of the vehicle has been moved will be sent to the electronic control unit 1 through a potentiometer; thus, the electronic control unit 1 will control the throttle 2 in order for the valve 22 to open to a certain degree according to the above-mentioned distance value as well as the signal of the throttle position sensor 3 so that the vehicle can shift gears earlier, and consumption of fuel can reduce.
  • the fuel feeding mechanism of the present invention has the following advantages over the prior art:
