Abstract
An idling speed control system of an electronic fuel injection motorcycle comprises a main air inlet channel, a throttle valve body installed on the main air inlet channel, a bypass air channel and an idling speed valve installed on the bypass air channel. One end of the main air inlet channel is communicated with an air filter, and the other end of the main air inlet channel is communicated with a cylinder of a motor. The idling speed control system of an electronic fuel injection motorcycle is characterized in that one end of the bypass air channel is communicated with the air filter and the other end of the bypass air channel is communicated with the main air inlet channel between the throttle valve body and the cylinder of the motor. The throttle valve body and an idling speed valve are installed in split so that installation space of the throttle valve body is no longer narrow. The split-type throttle valve body is compact in structure, small in volume and convenient to arrange and install, and resolves the problem that because compatibility, namely commonality of an integrated throttle valve body is poor, opening molds need to be designed for different motors and cost is increased.
Description
Technical field
The utility model relates to the engine idle device, especially the motorcycle with electronic fuel injection system Wo 2009051153.
Background technique
At present, along with the enforcement of motorcycle state three, the electronic fuel injection technology progressively is applied, and adopts traditional mode to the control of engine idle on the market in automatical control system.Promptly an integrated bypath air road on throttle body utilizes idle speed executor to control the bypath air amount that enters motor by this air flue, thereby reaches the purpose of control engine idle.Because it is less that motorcycle is installed the location space of motor, on throttle body, want integrated idle speed executor, can allow the throttle body installing space become narrower.Simultaneously for the different displacements motor, different automobile types, the compatibility of integrated form throttle body can be very poor, all will redesign and die sinking different motors thereby cause, and increases cost.
The model utility content
Technical problem to be solved in the utility model is, narrow at existing motorcycle with electronic fuel injection system Wo 2009051153 integrated form throttle body installing space, the problem of versatility difference, it is bigger to provide a kind of throttle body that installing space is installed, the motorcycle with electronic fuel injection system Wo 2009051153 of highly versatile.
In order to solve the problems of the technologies described above, the utility model provides a kind of motorcycle with electronic fuel injection system Wo 2009051153, comprise main air intake, be installed in throttle body, the bypath air road on the main air intake and be installed in idle valve on the bypath air road, main air intake one end is communicated with air-strainer, the other end is communicated with engine cylinder, it is characterized in that described bypath air road one end is communicated with air-strainer, the other end is communicated with the main air intake between the engine cylinder-body with throttle body.
Based on motorcycle with electronic fuel injection system Wo 2009051153 of the present utility model, throttle body and idle valve partial installation make the throttle body installing space no longer narrow.Split type throttle valve structure is succinct, and volume is little, is convenient to arrange install, and solves because the poor compatibility of integrated form throttle body is that universal performance is poor, need increase the problem of cost to different motor redesign die sinkings.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is described in further detail.
As shown in Figure 1, motorcycle with electronic fuel injection system Wo 2009051153 of the present utility model comprises main air intake 1a, throttle body 2 and idle valve 3, and wherein main air intake 1a one end is communicated with air-strainer 1, the other end is communicated with the cylinder of motor 4, and throttle body 2 is installed on the main air intake 1a.Blowing air road 1b on one side is set outside throttle body 2, this bypath air road 1b one end is communicated with air-strainer 1, the other end is communicated with the idle valve 3 of 1b cross section, installation and control bypath air road aperture on the bypath air road with throttle body 2 with the main air intake 1a between motor 4 cylinders.
When motor 4 was idle, system's control throttle body 2 was closed main air intake 1a, controlled idle valve 3 work simultaneously, and the cross section aperture of control bypath air road 1b makes the idling of motor 4 suitable.
Because adopt throttle body 2 and idle valve 3 partial installations, the throttle body installing space is no longer narrow.Throttle body 2 and idle valve 3 are arranged and are installed and all compare flexibly, solve the problem of the poor compatibility of integrated form throttle body, have avoided different engine idle actuator's redesigns and die sinking, the problem that causes cost to increase.
The foregoing description of the present utility model only is to be explanation the utility model example, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
