Description
Technical field
The utility model relates to a kind of motorcycle engine gas handling system, relates in particular to a kind of making-up air device of motorcycle engine.
Background technique
According to national Specification, the automobile exhausting standard will reach No. 2 standards in Europe, and the mixed gas that the acting of present motorcycle engine produces is the relief opening through engine cylinder head, enters the atmosphere from the outlet pipe silencing apparatus.Because mixed gas is fully burning not, contains compounds such as CO, NO, HC, directly discharging does not reach No. 2 standards in Europe, causes environmental pollution.
In order to reduce the motorcycle exhaust environmental pollution caused by discharge, one of method of mainly taking at present is that motor is carried out secondary air compensating, promptly the exhaust ports at engine cylinder head connects the secondary air compensating suction tude, the negative pressure that produces in the cylinder head exhaust ports during by engine exhaust, fresh air is sucked relief opening through this suction tude, make the waste gas of discharge carry out secondary combustion, to improve the exhaust emission quality of motor in exhaust ports.The defective that this kind technological scheme exists is: fresh air is to suck relief opening through the secondary air compensating suction tude under suction function, because there is structural difference in the exhaust silencer of different structure, this will make with the exhaust resistance of the motor of the exhaust silencer of different structure coupling different, thereby the difference that causes the tonifying Qi effect, make the conversion ratio instability of engine exhaust, finally cause the quality instability of engine exhaust emission.
Application number is that 200520009575.6 Chinese patent discloses a kind of motorcycle secondary making-up air device, in the heat sink area of engine cylinder head outer surface, be provided with mounting plane, the central authorities of this mounting plane have inlet hole, inlet hole communicates with the relief opening of cylinder head, and the outside of inlet hole by connecting tube and negative pressure type secondary air valve the air outlet be communicated with, the suction port of negative pressure type secondary air valve then is communicated with empty filter by the air valve suction tude, and the negative pressure mouth of negative pressure type secondary air valve is communicated with engine air inlet tube on the cylinder head.The defective that this kind technological scheme exists is: motorcycle institute discharge tail gas amount is different and change along with engine operating condition, but to go be a definite value to the motorcycle secondary air compensation, can not adapt to the variation of the different operating modes of motorcycle.
The model utility content
The purpose of this utility model is at above-mentioned deficiency of the prior art, the motorcycle engine making-up air device that provides a kind of and existing motorcycle secondary making-up air device to be used.This apparatus structure is simple, realizes that the motor air compensation is adjustable, can adapt to the variation of the different operating modes of motorcycle.
For achieving the above object, the utility model solves the technological scheme that its technical problem adopts and is:
A kind of making-up air device of motorcycle engine, comprise first air chamber, be fixed on the screw cap on the first air chamber top by screw thread, be positioned at the first air chamber bottom and with the modulating valve of the first air chamber inner wall sealing, be positioned at the air outlet of first air chamber bottom, be fixedly connected on second air chamber of the outside side of first air chamber, the middle part of described first air chamber is provided with coil tension spring, the two ends of this coil tension spring are connected with " U " type support on the modulating valve with screw cap respectively, have center hole on the described screw cap, the autobicycle gasoline throttle line passes center hole and links to each other with " U " type support, link to each other with first air chamber air hole that is provided with of a side of second air chamber, the side that second air chamber is relative with air hole is provided with suction port.
As optimal way, described modulating valve is realized sealing by the seal ring and the first air chamber lower wall.
As optimal way, the upper end of described center hole is provided with sealing.
Adopt said structure, key is that the sealing of center hole upper end can make realization sealing between first air chamber and the space outerpace.
As optimal way, described air hole is set to 5.
As optimal way, described air outlet is provided with the magnetic body.
Adopt said structure, key is that the strong magnetism of magnetic body can make the air molecule magnetization, makes oxygen molecule activation back proper alignment, and the fuel oil with atomizing mixes fully rapidly, effectively improves combustion efficiency.
Working principle of the present utility model is: the suction port of motorcycle engine making-up air device communicates with air-strainer by pipeline, and the air outlet of motorcycle engine making-up air device communicates with engine air inlet tube on the cylinder head by pipeline.
1, under engine idling condition, the exhausted air quantity minimum that motorcycle produced, the air compensation of original motorcycle secondary making-up air device is enough, is in sealing state between second air chamber and first air chamber, does not carry out tonifying Qi.
2, under the medium engine speed operating mode, the exhausted air quantity that motorcycle produced is bigger, the air compensation deficiency of original motorcycle secondary making-up air device, throttle line spurs modulating valve to top offset one segment distance by coil tension spring, second air chamber communicates with first air chamber by the part air hole, and the air in the air-strainer is mended into motor.
3, under the high engine speeds operating mode, the exhausted air quantity maximum that motorcycle produced, the air compensation deficiency of original motorcycle secondary making-up air device, throttle line spurs modulating valve again to top offset one segment distance by coil tension spring, second air chamber communicates with first air chamber by whole air holes, and a large amount of benefits of the air in the air-strainer are gone into motor.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is skillfully constructed, simple in structure, realize that the motor air compensation is adjustable, can adapt to the variation of the different operating modes of motorcycle.
