Description
Technical field
The utility model belongs to technical field of motorcycles, specifically, and particularly a kind of mounting structure of motorcycle with electronic fuel injection system idling gulp valve.
Background technology
The idling gulp 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 driving engine.As shown in Figure 4, the admission piece 2a of idling gulp valve 2 is connected with joint 5 on the empty filter 1 by air induction hose 4, and the outlet nozzle 2b of idling gulp valve 2 is connected with driving engine by the flexible pipe 6 of giving vent to anger.Described idling gulp valve 2 and fixes by a mounting bracket and two installation clips and vehicle frame between empty filter 1 and driving engine.The deficiency of said structure is:
1) the tonifying Qi path is longer, can influence the tonifying Qi efficient to driving engine;
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 gulp 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 themperature of mending into driving engine by flexible pipe is higher than ambient-air temperature, can cause the erroneous judgement of the suction quantity of ECU like this, thereby influence the air/fuel ratio of driving engine;
4) assembling of idling gulp valve needs a plurality of accessories such as support, clamp, and productive costs is higher.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of easy mounting structure of idling gulp valve on empty filter that assemble.
The technical solution of the utility model is as follows: the mounting structure of a kind of idling gulp valve on empty filter, comprise sky filter (1) and idling gulp valve (2), front bulkhead at empty filter (1) is equipped with throttle gate connection pipe (3), described idling gulp valve (2) is positioned at the below of throttle gate connection pipe (3), this idling gulp valve (2) is inlaid on the front bulkhead of sky filter (1), and compress the location by support (7), the admission piece (2a) of described idling gulp valve (2) is positioned at sky filter (1), and the outlet nozzle (2b) of idling gulp valve (2) is outside empty filter (1).
The utility model directly is installed on the idling gulp valve on the front bulkhead of sky filter, installs simply, convenient, effectively reduces the difficulty of assembly manipulation; The idling gulp valve adopts fixedly that the mode of setting-in is connected with empty filter, and is compressed by support, not only firmly but also reliable, can not take place to become flexible or come off.The idling gulp valve only needs be connected with driving engine 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 driving engine 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 themperature and ambient-air temperature basically identical into driving engine, thereby prevented that effectively the suction quantity of ECU from producing erroneous judgement.Simultaneously, the idling gulp valve utilizes the free space of throttle gate connection pipe 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 gulp valve (2) has 12-20 ° angle between the axial line of idling gulp valve (2) and the horizontal surface.Above structure is idling gulp valve and the throttle gate connection pipe certain angle that staggers on the one hand, and installation idling gulp valve is more convenient, quick; On the other hand, the admission piece of idling gulp valve enters the gas abundance of idling gulp valve like this towards the airintake direction of empty filter by admission piece, can guarantee air compensation and the tonifying Qi efficient of driving engine.The axial line of idling gulp valve and the angle between the horizontal surface are advisable with 12-20 °, and angle is too small or cross assembling and the tonifying Qi effect that big city influences the idling gulp valve.
The main body of described idling gulp valve (2) is arranged in the mounting hole on sky filter (1) front bulkhead, the main body of idling gulp valve (2) fixes by the front bulkhead of sealant and empty filter (1), and the step surface on idling gulp valve (2) main body is close on the front end face of sky filter (1).Above structure can make the assembling of idling gulp valve easier, and has further improved the fixing that the idling gulp valve is installed.
Described support (7) is " Z " shape, formed by compressing tablet (7a), transition plate (7b) and spacer (7c), compressing tablet (7a) links to each other with spacer (7c) by transition plate (7b), described spacer (7c) fits with the front bulkhead of empty filter (1), and pass through bolt, described compressing tablet (7a) is parallel to spacer (7c), and this compressing tablet (7a) is oppressed from front to back on idling gulp valve (2).Above structure support moulding on the one hand is simple, and it is convenient to install; On the other hand, it is firm that support is installed at empty filter, and support can be pressed on the idling gulp valve on the sky filter all the time, loosening to prevent that the idling gulp valve from taking place.
Described support (7) is by punch forming, and processing and fabricating is easy like this, and cost is low.Described compressing tablet (7a) is circular arc, and compressing tablet can be avoided outlet nozzle and the reinforced rib of idling gulp valve, avoids interfering; Simultaneously, compressing tablet is bigger with the zone that the idling gulp valve contacts, and can guarantee the thrust to the idling gulp valve.Described spacer (7c) is rectangle, fits closely between spacer and the empty filter, can strengthen the fastness that connects.
Beneficial effect: the utility model is directly installed on the idling gulp valve on the sky filter, simple installation not only, fixing is good, and shortened the length of tonifying Qi path greatly, improved the efficient to the driving engine tonifying Qi, have characteristics such as reasonable in design, that enforcement is easy, improvement cost is low, on various motorcycle with electronic fuel injection system, all be suitable for.
