Description
- 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.
- Vehicles are among necessities of daily life, which provide people with better mobility and convenience. Most of the fuels of vehicles are extracted from petroleum. Petroleum isn't a kind of inexhaustible natural resource, and it can be dried up very soon. Furthermore, combustion of petrolic fuels will produce much air pollution. In order to deal with the above problems, many manufacturers are devoting much money and time to developing better products and manufacturing method so that less energy is consumed in manufacturing. In the light of the fact that a large proportion of gasoline is consumed with vehicles, many people decide to reduce use of cars as much as possible, and the industry are devoting much effort to developing more advanced fuel feeding mechanisms for vehicles in order for the vehicles to consume less fuel in running.
- 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. Furthermore, 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 above vehicle fuel-feeding mechanism is found to have the following drawbacks:
- 1. With the fuel-feeding mechanism, the engine of the vehicle will increase the rotational speed in order to speed up the vehicle in gear-shifting. Consequently, a large amount of fuel will be consumed.
- 2. For the above reason, many drivers decide to re-equip their car engines in order to reduce the expense on fuel. However, such a re-equip takes much money, and re-equips are usually different for the engines of vehicles of different models.
- In the light of the fact that the above vehicle fuel-feeding mechanism will consume a much greater amount of fuel in gear-shifting, and it will take much time, labor, and expense to re-equip the vehicle engine, 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 according to an embodiment of the present invention 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.

Figs. 1 and2 , a first preferred embodiment of a fuel feeding mechanism of a vehicle in the present invention includes an electronic control unit (ECU) 1, athrottle 2, and a throttle position sensor (TPS) 3. - 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 toFig. 3 as well, thethrottle 2 comprises apivotal shaft 21, and avalve 22 pivoted on thepivotal shaft 21. Furthermore, thethrottle 2 is connected to afeedback signal device 23. - The
throttle position sensor 3 includes avariable resistor 31, which will change in its resistance when being rotated. Thethrottle position sensor 3 includes asignal source 32, which is connected to thevariable resistor 31. Referring toFigs. 4 and5 as well, thethrottle position sensor 3 further includesadjustment buttons 33 for a start of thethrottle position sensor 3,adjustment buttons 34 for stoppage of thethrottle position sensor 3, and indicatinglamps 35. Theadjustment buttons 33 for start are used to set a floor value of a rotational speed of the engine; thethrottle position sensor 3 will be activated, and a stable voltage will be transmitted to theelectronic control unit 1 as soon as the rotational speed of the engine reaches the floor value. Theadjustment buttons 34 for stoppage are used to set a ceiling value of a rotational speed of the engine; thethrottle position sensor 3 will be turned off, and a stable voltage will be transmitted to theelectronic control unit 1 as soon as the rotational speed of the engine reaches the ceiling value. The indicatinglamps 35 are used to show a current set value of rotational speed of the engine in the above setting. - In assembly, referring to
Fig. 1 to Fig. 4 , thefeedback signal device 23 of thethrottle 2 is connected to theelectronic control unit 1; thus, a signal of thevalve 22 opening is feedback to theelectronic control unit 1 in order for theelectronic control unit 1 to make the engine to run on an optimum amount of fuel injection. Thevariable resistor 31 of thethrottle position sensor 3 is installed on thepivotal shaft 21 of thethrottle 2 so as to change in its resistance in rotational motion of thepivotal shaft 21. Thesignal source 32 of thethrottle position sensor 3 is connected tofeedback signal device 23 of thethrottle 2; thesignal source 32 is used to transmit a signal to theelectronic control unit 1, which is slightly smaller than the signal feedback from thethrottle 2 to theelectronic control unit 1, so as to interfere in and change the signal of thethrottle 2; thus, the time of the vehicle shifting gears is advanced. For example, the rotational speed of the vehicle engine is 2500RPM/ 60KM originally, and will become 2200RPM/ 60KM after the signal is changed. - To put the fuel feeding mechanism of the present invention to use, referring to
Fig. 1 to Fig. 4 , the driver uses theadjustment buttons 33 to set a floor value of rotational speed of the engine, and uses theadjustment 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. And, thethrottle position sensor 3 will send a stable voltage feedback to theelectronic control unit 1, and in turn theelectronic 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. - Shown in
Fig. 6 to Fig. 8 is the second preferred embodiment of a fuel feeding mechanism of a vehicle in the present invention. 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 theelectronic control unit 1. The acceleratorpedal 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 theelectronic control unit 1 through a potentiometer; thus, theelectronic control unit 1 will control thethrottle 2 in order for thevalve 22 to open to a certain degree according to the above-mentioned distance value as well as the signal of thethrottle position sensor 3 so that the vehicle can shift gears earlier, and consumption of fuel can reduce. - From the above description, it can be seen that the fuel feeding mechanism of the present invention has the following advantages over the prior art:
- 1. The throttle position sensor of the present invention includes a variable resistor, and a signal source, which is connected to the variable resistor as well as the feedback signal device of the throttle so as to interfere in and change the signal of the throttle. Furthermore, the present invention includes an accelerator pedal position sensor, which is used to control the throttle together with the throttle position sensor so as to help to advance the time of the vehicle shifting gears and reduce consumption of fuel.
- 2. The fuel feeding mechanism is suitable for use with vehicles of any model to save fuel. And, it is more economical to use the fuel feeding mechanism than it is to re-equip the vehicle engine. Therefore, the present invention is very practical.
