Abstract
The utility model discloses an idling gulp valve arrangement structure which comprises an air filter (1) and an idling gulp valve (2). A throttle valve connecting pipe (3) is arranged on the front end wall of the air filter (1), the idling gulp valve (2) is located below the throttle valve connecting pipe (3), an air inlet mouth (2a) of the idling gulp valve (2) extends into a seal rubber sleeve (7) and is fixed in the seal rubber sleeve (7), and the seal rubber sleeve (7) is fixedly embedded on the front end wall of the air filter (1). According to the idling gulp valve arrangement structure, the idling gulp valve is directly arranged on the air filter through the seal rubber sleeve, the idling gulp valve arrangement structure is simple and convenient to install and good in firmness, greatly shortens the length of an air admission channel, improves air admission efficiency of an engine, has the advantages of being reasonable in design, easy to implement, low in modification cost and the like, and is applied to various electric injection motorcycles.
Description
Technical field
The utility model belongs to technical field of motorcycles, specifically, and particularly a kind of layout of motorcycle with electronic fuel injection system idling aeration valve.
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 the air inflow of ECU like this, thereby influence the air fuel ratio of motor;
4) assembling of idling aeration valve needs a plurality of accessories such as support, clamp, and cost of production is higher.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of easy idling aeration valve layout that assembles.
The technical solution of the utility model is as follows: a kind of idling aeration valve layout, comprise sky filter (1) and idling aeration valve (2), front bulkhead at empty filter (1) is equipped with closure connecting tube (3), described idling aeration valve (2) is positioned at the below of closure connecting tube (3), the air inlet nozzle (2a) of this idling aeration valve (2) stretches into and is fixed in the seal rubber sleeve (7), and described seal rubber sleeve (7) fixedly is inlaid on the front bulkhead of sky filter (1).
The utility model directly is installed on the idling aeration valve on the front bulkhead of sky filter by seal rubber sleeve, 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 into motor, thereby prevented that effectively the air inflow of ECU from producing erroneous judgement.Simultaneously, the idling aeration valve utilizes the free space of closure connecting tube below to arrange, has both reduced taking up room of self, is conducive to 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) has 12-20 ° angle between the shaft axis of idling aeration valve (2) and the horizontal plane.Above structure is idling aeration valve and the closure connecting tube several angle that staggers on the one hand, and installation idling aeration valve is more convenient, quick; On the other hand, the air inlet nozzle of idling aeration valve enters the gas abundance of idling aeration valve like this towards the airintake direction of empty filter by air inlet nozzle, can guarantee 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 rear end of described seal rubber sleeve (7) is the roundlet header structure, and front end is the great circle header structure, is formed with annular groove between the big or small round end of seal rubber sleeve (7), and seal rubber sleeve (7) is inlaid on the front bulkhead of sky filter (1) by this annular groove.The little round end of seal rubber sleeve rear end has leading role, so that pass the mounting hole on the sky filter front bulkhead, extend in the sky filter; The annular groove of size between the round end plays screens, makes between seal rubber sleeve and the empty filter to be connected firmly, reliably, and seal rubber sleeve can not take place to become flexible or come off.
Beneficial effect: the utility model is directly installed on the idling aeration valve on the sky filter by seal rubber sleeve, simple installation not only, fixing is good, and shortened the length of tonifying Qi path greatly, improved the 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of background technique.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is made up of empty filter 1, idling aeration valve 2, closure connecting tube 3 and seal rubber sleeve 7, closure connecting tube 3 is equipped with on top at empty filter 1 front bulkhead, and structure and the mounting type of closure connecting tube 3 are same as the prior art, do not give unnecessary details at this.Bottom at described empty filter 1 front bulkhead has mounting hole, and seal rubber sleeve 7 is packed in this mounting hole.The rear end of described seal rubber sleeve 7 is the roundlet header structure, front end is the great circle header structure, between the big or small round end of seal rubber sleeve 7, be formed with annular groove, seal rubber sleeve 7 is inlaid in the mounting hole of sky filter 1 front bulkhead by this annular groove, the little round end of seal rubber sleeve 7 rear ends is positioned at sky filter 1, and the big round end of seal rubber sleeve 7 front ends is outside empty filter 1.Described idling aeration valve 2 low early and high after being obliquely installed, the air inlet nozzle 2a of idling aeration valve 2 stretches in the seal rubber sleeve 7, and both are by being tightly fixed together, and the outlet nozzle 2b of idling aeration valve 2 is connected (not drawing among the figure) by the flexible pipe of giving vent to anger with motor.The angle that has 12-20 ° between the shaft axis of described idling aeration valve 2 and the horizontal plane, in the present embodiment, this angle is preferably 15 °.
