Abstract
The utility model discloses an improved motorbike electronic spray throttle which comprises a throttle body (2) and an ECU (engine control unit), and a position sensor (4) arranged on the throttle body is electrically connected with the ECU. The throttle is characterized in that a fuel pump fixing seat (8) is arranged on the throttle body, a fuel pump (5) is mounted on the fuel pump fixing seat, and the fuel pump and the ECU are electrically connected. The throttle solves the problem in the background technology that the oil tank is required to be refit for mounting the fuel pump, which is troublesome and increases the cost. Additionally, the fuel pump is directly mounted on the throttle body, and the oil is pressurized by the fuel pump and then directly sprayed by an injection nozzle, thereby reducing the length of a high pressure fuel pipe, and increasing the safety factor.
Description
Technical field
The utility model relates to a kind of improvement invention of electrospray throttle valve, particularly be the electrospray throttle valve that a kind of motorcycle engine is used.
Background technique
At present, the electric injection system that is used for the motorcycle of big discharge capacity, its structural configuration is distributed, be that the system throttle body, ECU, various sensor and the fuel pump that have are arranged apart on engine oil tank and vehicle body, position transducer and some mechanical parts often only are housed on the throttle body, and the electronic fuel pump that is used to increase fuel pressure is not installed in throttle body.Just there is following problem in this structure: one, since fuel pump be installed in and make each car all need to reequip fuel tank in the fuel tank to cooperate fuel pump, so just increased cost of production; Two, because fuel pump is installed in the fuel tank, the fuel from fuel tank after the pressurization just needs one section long high-pressure oil pipe to oil nozzle like this, so just causes bigger potential safety hazard; Three, along with the difference of engine model, throttle body mounting structure difference, the motorcycle electric spraying system of different model can not be compatible, makes the development cost of motorcycle electric spraying system increase.
Summary of the invention
In view of the existing technical problem of known technology, technical problem to be solved in the utility model provides and a kind ofly reduces cost and improve the electrospray throttle valve of safety coefficient that motorcycle starts level.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize: this kind motorcycle electric spraying closure, include tb and ECU, described tb is provided with position transducer, described position transducer and ECU electrical coupling, it is characterized in that described tb is provided with the fuel pump fixed base, on described this fuel pump fixed base fuel pump is installed, described fuel pump and ECU electrical coupling.
Described fuel pump fixed base is arranged on the bi-side of tb.
Described fuel pump is fixed on the fuel pump fixed base by the heat radiation cover plate.
Described tb is provided with air inlet pressure sensor, described air inlet pressure sensor and ECU electrical coupling.
Described tb is provided with intake air temperature sensor, described intake air temperature sensor and ECU electrical coupling.
Described closure tb has an endoporus, and described diameter of bore is 14～45 millimeters.
The utility model is directly installed on fuel pump on the closure, so just need not to reequip fuel tank, has solved in the background technique because of installing that fuel pump need be reequiped the trouble of fuel tank and because of repacking increases the problem of cost, thereby has reduced cost; After fuel pump was directly installed on the tb, fuel pump was directly sprayed by oil nozzle after oil is pressurizeed, and therefore can ignore the length of high-pressure oil pipe basically, has improved safety coefficient widely; And each sensor and fuel pump and closure become one, and just solved the incompatible problem of motorcycle electric spraying system of closure and different model in the background technique, thus the expense of having saved the exploitation electric injection system.The bi-side of tb respectively are provided with the fuel pump fixed base, and fuel pump can select different azimuth to install, thereby have satisfied the motorcycle electric spraying system of different mounting points; Adopt heat radiation cover plate lid press fit fuel pump, it is more firm to make fuel pump install; The diameter of bore of tb is arranged between 14～45 millimeters, to cooperate the motorcycle electric spraying system of various discharge capacities.

Embodiment
With reference to Fig. 1, motorcycle electric spraying closure in the present embodiment, include tb 2, fuel pump 5 and ECU, described tb 2 front and back sides are provided with position transducer 4, air inlet pressure sensor 3, intake air temperature sensor 1, the left and right sides of described tb 2 is equipped with fuel pump fixed base 8, described fuel pump fixed base 8 is provided with the structure hole 9 of four rectangular layouts, described this structure hole 9 is complementary with heat radiation cover plate 6, and described fuel pump 5 is pressed on the fuel pump fixed base 8 by heat radiation cover plate 6 lids.Each sensor on described fuel pump 5 and the tb 2 all with the ECU electrical coupling, described tb 2 has an endoporus 7, the diameter of described endoporus 7 is 14～45 millimeters, endoporus 7 diameters that adopt in the present embodiment are 30 millimeters.
During the utility model work, be installed in position transducer 4 on the tb 2 to the voltage signal of ECU feedback throttle opening, be installed in air inlet pressure sensor 3 on the tb 2 and intake air temperature sensor 1 then to the signal of ECU feedback suction pressure and temperature level.ECU is according to the operating conditions of judgement place motors such as the temperature transducer on various sensors and the motor, lambda sensor, and the air inflow of calculation engine, obtain fuel injection pulsewidth, the moment and ignition advance angle according to the MAP figure in the ECU storage again, the best time of oil mass that control fuel pump 5 sprays and high pressure packet igniting, the injection of accurate control oil mass, promptly reduce the waste of fuel oil, saved the energy, reduced cost.
The utility model is arranged on fuel pump 5 and position transducer 4, air inlet pressure sensor 3, intake air temperature sensor 1 on the tb 2 simultaneously, form an air-throttle assemble, reduced change with respect to existing distributing setting to former car, reduced cost, shorten the length of high-pressure oil pipe, improved safety coefficient; And the two-way fuel pump fixed base 8 that is provided with on the tb 2 can be complementary with the motorcycle electric spraying system of different azimuth, and the design of endoporus 7 sizes of closure then is applicable to the motorcycle electric spraying system of each discharge capacity.Therefore, the utility model compared with prior art has substantive distinguishing features and progress.
