Description
Technical field
The invention belongs to technical field of motorcycles, specifically, particularly a kind of motorcycle with electronic fuel injection system idle supplement valve and air filter linkage structure.
Background technique
Idle supplement valve is the vitals on motorcycle with electronic fuel injection system, for being filled in motor by the fresh air in air filter.As shown in Figure 2, the air inlet nozzle 2a of idle supplement valve 2 is connected with the joint 5 in air filter 1 by air induction hose 4, and the outlet nozzle 2b of idle supplement valve 2 is connected with motor by air-out hose 6.Described idle supplement valve 2 between air filter 1 and motor, and is fixed by a mounting bracket and two installation clips and vehicle frame.The deficiency of said structure is:
1) tonifying Qi path is longer, can affect the tonifying Qi efficiency to motor;
2) 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 more difficult, and efficiency of assembling is not high;
3) air induction hose of idle supplement valve and air-out hose pass through from the top of engine cylinder cover, because the temperature of engine cylinder cover is very high, the impact of thermal radiation, the air temperature of motor is filled into higher than atmospheric temperature by flexible pipe, ECU can be caused like this to the erroneous judgement of air inflow, thus affect the air fuel ratio of motor;
4) assembling of idle supplement valve needs multiple accessory such as support, clamp, and cost of production is higher.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of assembles easy motorcycle with electronic fuel injection system idle supplement valve and air filter linkage structure.
Technological scheme of the present invention is as follows: a kind of motorcycle with electronic fuel injection system idle supplement valve and air filter linkage structure, comprise air filter (1) and idle supplement valve (2), the front bulkhead of air filter (1) is equipped with closure connecting tube (3), the main body of described idle supplement valve (2) is pre-large post-small ledge structure, described idle supplement valve (2) is positioned at the below of closure connecting tube (3), the small stair section (2c) of this idle supplement valve (2) main body stretches into together with air inlet nozzle (2a) in the leading portion endoporus of encapsulate Membrane cover (7), by being tightly fixed between the small stair section (2c) of idle supplement valve (2) main body and encapsulate Membrane cover (7), the rear end of described encapsulate Membrane cover (7) is fixedly inlaid on the front bulkhead of air filter (1).
Idle supplement valve is installed on the front bulkhead of air filter by encapsulate Membrane cover by the present invention, and it is simple, convenient not only to install, and fixing is good, and decreases the use of the accessory such as support, clamp, effectively reduces cost of production.Idle supplement valve only need be connected with motor by an air-out hose, substantially reduces the length of tonifying Qi path so on the one hand, improves the efficiency to motor tonifying Qi; On the other hand, the position that whole tonifying Qi path passes through above engine cylinder cover is reduced, the corresponding reduction of impact by engine cylinder cover temperature, air temperature and the atmospheric temperature that can guarantee to fill into motor are basically identical, thus effectively prevent ECU and produce erroneous judgement to air inflow.Meanwhile, idle supplement valve utilizes the free space below closure connecting tube to arrange, has both decreased taking up room of self, is conducive to workman's fitting operation, again saves the space below fuel tank, so that assemble other parts.
Described idle supplement valve (2) is low early and high after to be obliquely installed, and the shaft axis of idle supplement valve (2) and the shaft axis of encapsulate Membrane cover (7), and have the angle of 12-20 ° point-blank between the shaft axis of idle supplement valve (2) and horizontal plane.Above structure on the one hand encapsulate Membrane cover and closure connecting tube staggers several angle, installation kit glue film sleeve and idle supplement valve more convenient, quick; On the other hand, the rear end of encapsulate Membrane cover and the air inlet nozzle of idle supplement valve, all towards the airintake direction of air filter, are entered the gas abundance of idle supplement valve like this, can guarantee air compensation and the tonifying Qi efficiency of motor by air inlet nozzle.Angle between the shaft axis of idle supplement valve and horizontal plane is advisable with 12-20 °, and angle is too small or cross assembling and the tonifying Qi effect that big city affects idle supplement valve.
The structure of described encapsulate Membrane cover (7) is identical with closure connecting tube (3), and the outer wall of encapsulate Membrane cover (7) rear end is formed with annular groove, and encapsulate Membrane cover (7) is inlaid on the front bulkhead of air filter (1) by this annular groove.The selection of encapsulate Membrane cover is convenient on the one hand for above structure, and need not make in addition, cost of production is low; On the other hand, the annular groove of encapsulate Membrane cover rear end plays screens, makes to be connected firmly between encapsulate Membrane cover and air filter, reliably, encapsulate Membrane cover can not occur to loosen or come off.
Beneficial effect: idle supplement valve is arranged in air filter by encapsulate Membrane cover by the present invention, not only simple installation, fixing is good, and substantially reduce the length of tonifying Qi path, improve the efficiency to motor tonifying Qi, there is the features such as reasonable in design, enforcement is easy, reforming cost is low, all applicable on various motorcycle with electronic fuel injection system.
