Abstract
The invention discloses an idle speed gulp valve and air filter connecting structure for an electronic injection motorcycle. A throttle valve connecting pipe (3) is arranged on the front end wall of an air filter (1). An idle speed gulp valve (2) is located under the throttle valve connecting pipe (3), a small step section (2c) of a main body of the idle speed pulp valve (2) and an air inlet nozzle (2a) are inserted into a front section inner hole of a package glue film sleeve (7), the small step section (2c) of the main body of the idle speed pulp valve (2) is fixed with the package glue film sleeve (7) in a tight fit mode, and the back end of the package glue film sleeve (7) is fixedly embedded in the front end wall of the air filter (1). Due to the fact that the idle speed gulp valve is arranged on the air filter through the package glue film sleeve, the idle speed gulp valve and air filter connecting structure for the electronic injection motorcycle not only is easy and convenient to install and good in reliability, but also greatly shortens the length of an air supply passage, improves air supply efficiency for an engine, has the advantages of being reasonable in design, easy to implement, low in improvement cost and the like, and is suitable for various electronic injection motorcycles.
Description
Technical field
The invention belongs to technical field of motorcycles, specifically, particularly a kind of motorcycle with electronic fuel injection system idling aeration valve and empty filter linkage structure.
Background technique
The idling aeration valve is the vitals on the motorcycle with electronic fuel injection system, is used for the fresh air of empty filter is mended in the motor.As shown in Figure 2, the air inlet nozzle 2a of idling aeration valve 2 is connected with joint 5 on the empty filter 1 by air induction hose 4, and the outlet nozzle 2b of idling aeration valve 2 is connected with motor by the flexible pipe 6 of giving vent to anger.Described idling aeration valve 2 and fixes by a mounting bracket and two installation clips and vehicle frame between empty filter 1 and motor.The deficiency of said structure is:
1) the tonifying Qi path is longer, can influence the tonifying Qi efficient to motor;
2) the tonifying Qi path is positioned at the below of fuel tank, and this segment space is less, and the layout of tonifying Qi path is installed difficulty, and efficiency of assembling is not high;
3) air induction hose of idling aeration valve and the flexible pipe of giving vent to anger pass through from the top of engine cylinder cover, because the temperature of engine cylinder cover is very high, the influence of thermal radiation, the air temperature of mending into motor by flexible pipe is higher than atmospheric temperature, can cause the erroneous judgement of ECU like this, thereby influence the air fuel ratio of motor air inflow;
4) assembling of idling aeration valve needs a plurality of accessories such as support, clamp, and cost of production is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of easy motorcycle with electronic fuel injection system idling aeration valve and empty filter linkage structure of assembling.
Technological scheme of the present invention is as follows: a kind of motorcycle with electronic fuel injection system idling aeration valve and empty filter linkage structure, comprise sky filter (1) and idling aeration valve (2), closure connecting tube (3) is housed on the front bulkhead of empty filter (1), the main body of described idling aeration valve (2) is pre-large post-small ledge structure, described idling aeration valve (2) is positioned at the below of closure connecting tube (3), the small stair section (2c) of this idling aeration valve (2) main body stretches in the leading portion endoporus of encapsulate Membrane cover (7) together with air inlet nozzle (2a), by being tightly fixed, the rear end of described encapsulate Membrane cover (7) fixedly is inlaid on the front bulkhead of sky filter (1) between the small stair section (2c) of idling aeration valve (2) main body and the encapsulate Membrane cover (7).
The present invention is installed on the idling aeration valve on the front bulkhead of sky filter by the encapsulate Membrane cover, not only installs simply, convenient, and fixing is good, and has reduced the use of accessories such as support, clamp, effectively reduces cost of production.The idling aeration valve only needs be connected with motor by the flexible pipe of giving vent to anger and gets final product, and one side has shortened the length of tonifying Qi path greatly like this, has improved the efficient to the motor tonifying Qi; On the other hand, whole tonifying Qi path reduces from the position that the engine cylinder cover top is passed through, be subjected to that the engine cylinder cover Temperature Influence is corresponding to be reduced, can guarantee to mend air temperature and atmospheric temperature basically identical, thereby prevented that effectively ECU from producing erroneous judgement to air inflow into motor.Simultaneously, the idling aeration valve utilizes the free space of closure connecting tube below to arrange, has both reduced taking up room of self, helps workman's fitting operation, has saved the space of fuel tank below again, so that assemble other parts.
Low early and high after being obliquely installed of described idling aeration valve (2), the shaft axis of the shaft axis of idling aeration valve (2) and encapsulate Membrane cover (7) and have 12-20 ° angle point-blank between the shaft axis of idling aeration valve (2) and the horizontal plane.Above structure is encapsulate Membrane cover and the closure connecting tube several angle that staggers on the one hand, and installation kit glue film sleeve and idling aeration valve are more convenient, quick; On the other hand, the air inlet nozzle of the rear end of encapsulate Membrane cover and idling aeration valve is all towards the airintake direction of empty filter, and the gas abundance that enters the idling aeration valve like this by air inlet nozzle can be guaranteed the air compensation and the tonifying Qi efficient of motor.The shaft axis of idling aeration valve and the angle between the horizontal plane are advisable with 12-20 °, and angle is too small or cross assembling and the tonifying Qi effect that big city influences the idling aeration valve.
The structure of described encapsulate Membrane cover (7) is identical with closure connecting tube (3), is formed with annular groove on the outer wall of encapsulate Membrane cover (7) rear end, and encapsulate Membrane cover (7) is inlaid on the front bulkhead of sky filter (1) by this annular groove.The selection of encapsulate Membrane cover is convenient on the one hand for above structure, needn't make in addition, and cost of production is low; On the other hand, the annular groove of encapsulate Membrane cover rear end plays screens, makes between encapsulate Membrane cover and the empty filter to be connected firmly, reliably, and the encapsulate Membrane cover can not take place loosening or come off.
Beneficial effect: the present invention is installed in the idling aeration valve on the sky filter by the encapsulate Membrane cover, simple installation not only, fixing is good, and shortened the length of tonifying Qi path greatly, improved efficient to the motor tonifying Qi, have characteristics such as reasonable in design, that enforcement is easy, reforming cost is low, on various motorcycle with electronic fuel injection system, all be suitable for.
