Background
One of the parts of the electronic fuel injection system used on the motorcycle is a throttle body, and the throttle body assembly comprises a stepping motor, a TPS sensor, a fuel injector, a valve body and a fuel injector bracket.
The motorcycle engine is divided into three states of low load, medium load and full load in operation, and the gas quantity of the medium load and the full load is basically from the main channel of the throttle valve body. According to the combustion principle of the gasoline engine, the mass ratio between air and fuel is known, and the fuel injection quantity is determined by knowing the air mass. The existing throttle valve body front section designs an oil sprayer, when in medium and low load, the front section oil sprayer designs oil spraying quantity to meet the engine requirement, but when in high speed, the engine speed is high, the air inlet load is larger, the oil-gas mixing time is short, poor oil-gas mixing atomization and insufficient oil spraying quantity are easily caused, and the engine is lower in power and poor in tail gas emission when in high speed.

In order to achieve the above purpose, the basic scheme of the utility model provides an electronic injection throttle valve assembly for a motorcycle, which comprises a throttle body, wherein the throttle body comprises a valve body air passage, a valve body reed is arranged in the valve body air passage, a front-end fuel injector is arranged on the throttle body, which is positioned on the front side of the valve body reed, and a rear-end fuel injector is also arranged on the rear side of the valve body reed.
The beneficial effect of this basic scheme lies in: by adopting the arrangement, when the engine works, according to the output power condition of the engine, especially when the engine is in a medium-high speed load state, the oil injection quantity of the front-end oil injector and the rear-end oil injector is adjusted and controlled, and compared with the prior art, the oil-gas mixing atomization effect is improved, and the output power of the engine under medium-high load is further improved.
Preferably, the included angle between the oil injection direction of the front-end oil injector and the air passage of the valve body is 17-27 degrees.
Preferably, the included angle between the oil injection direction of the front-end oil injector and the air passage of the valve body is 22 degrees. By adopting the arrangement, the front-end fuel injector can meet the fuel injection requirement of the engine at a high speed while meeting the fuel injection requirement of the engine at a low speed.
Preferably, the included angle between the oil injection direction of the rear-end oil injector and the air passage of the valve body is 22-32 degrees.
Preferably, the included angle between the oil injection direction of the rear-end oil injector and the air passage of the valve body is 27 degrees. By adopting the arrangement, the power of medium and high load of the engine can be improved by 5% -10% by matching with the use of the front-end fuel injector, and the exhaust emission condition of the engine is improved, so that the performance of the engine is improved.
Drawings
FIG. 1 is a schematic view of an embodiment of an electronic injection throttle assembly for a motorcycle in accordance with the present utility model;
FIG. 2 is a top view of FIG. 1;
fig. 3 is a cross-sectional view A-A of fig. 2.
Detailed Description
In the utility model, the front side of the valve body reed refers to the windward side of the valve body reed when air flows through the throttle body. Similarly, the back side of the valve body reed refers to the lee side of the valve body reed when the air flow passes through the throttle body.
The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: throttle body 1, back-end sprayer 2, front-end sprayer 3, step motor 4, valve body reed 5, valve body air flue 6, oil column 7.
An embodiment is substantially as shown in figures 1 to 3 of the accompanying drawings: an electronic injection throttle valve assembly for a motorcycle comprises a throttle body 1, wherein the throttle body 1 is cylindrical in the embodiment. The throttle body 1 comprises a valve body air passage 6, a valve body reed 5 is arranged in the valve body air passage 6, and the valve body reed 5 is connected with the throttle body 1 through a rotating shaft, so that the air inflow of the valve body air passage 6 is controlled by rotating the valve body reed 5. In this embodiment, a stepping motor 4 for controlling rotation of a valve body reed 5 is mounted on a throttle body 1.
The front end fuel injector 3 is arranged on the front side of the valve body reed 5 on the throttle valve body 1, and specifically, a mounting hole for mounting the front end fuel injector 3 is arranged on the throttle valve body 1, so that the front end fuel injector 3 is conveniently mounted and fixed. In this embodiment, the angle between the injection direction of the front-end injector 3 and the valve body air passage 6 is 17 ° -27 °, preferably 22 °. And the oil column 7 sprayed from the front-end oil sprayer 3 passes through the area where the valve body reed 5 is arranged from one side of the rotation axis of the valve body reed 5, thereby reducing the influence of the valve body reed 5 on the oil spraying effect of the front-end oil sprayer 3.
In this embodiment, the rear side of the valve body reed 5 is further provided with the rear end fuel injector 2, specifically, the throttle body 1 is provided with a mounting hole for mounting the rear end fuel injector 2, thereby facilitating the mounting and fixing of the rear end fuel injector 2. The included angle between the oil injection direction of the rear-end oil injector 2 and the valve body air passage 6 is 22-32 degrees, preferably 27 degrees.
The specific implementation process is as follows:
when the engine works, according to the output power condition of the engine, especially when the engine is in a medium and high speed load state, the oil injection quantity of the front end oil injector 3 and the rear end oil injector 2 is adjusted and controlled, so that the oil-gas mixing atomization effect under various power conditions of the engine is ensured, and the output power of the engine under medium and high load is improved. Compared with the prior art, the power of the engine under medium and high load is improved by 5-10 percent through test verification.
