Establish tool one oil gas suction tude on the housing of this outside air chamber one end, and be provided with a dividing plate in the outside air chamber, form an oil gas and reclaim the chamber, the oil gas suction tude reclaims the chamber with oil gas and is connected, and this oil gas recovery chamber has another breathing pipe and is connected with inner plenum, oil gas reclaims and was provided with a carbon dust bag in indoor year simultaneously, in order to reclaim the oil gas that is written into from the oil gas suction tude, and the mat breathing pipe is written into inner plenum, make with fresh air and mix, and to the burning of air outlet slit discharge supply engine, formation one and the incorporate oil gas recover of air filter housing;

And establish and a secondary air control valve on the housing of this inner plenum one end, this secondary air control valve, after filtration fresh air in the inner plenum is supplied to auxiliary catalytic control waste gas in the outlet pipe, forms another and the incorporate secondary air control valve of air filter housing.

Except that above-mentioned essential features, in specific implementation process, this breathing pipe is on the sealing gasket of being located in the housing, is communicated with oil gas and reclaims chamber and inner plenum.

The utility model is to utilize the integrated three-in-one unit that an oil gas recover and another secondary air control valve are set of an air filter housing; Comprise and utilize existing refill filtering element (cartridge) in the air filter housing, come outside the required air of filter engine burning, and mat enclosure interior space planning group is established the oil gas recover with carbon dust bag, the oil gas of fuel tank evaporation is recovered, and in housing the air of filtering supply with engine combustion and use, the planning group is established secondary air control valve simultaneously and on housing, makes that the part air of filtering can be directly for draining into outlet pipe in the housing, and auxiliary catalytic control waste gas uses; Mat makes air-strainer, oil gas recover and secondary air control valve three can do an effective combination, to reach the purpose of saving the space, simplifying structure, reduce cost and reducing transfer impedance.

Advantage of the present utility model is:

The integrated device of a kind of air cleaner for motorcycle provided by the utility model, oil gas recover, secondary air control valve, can make full use of the existing shell space of air-strainer, and the existing environment of filtering supply engine burning required air, an integrated oil gas recover and another secondary air control valve in addition, have the filtering air, reclaim the integrated three-in-one unit of oil gas and supply catalytic control waste gas required air with formation, and then reach the purpose of saving the space, simplifying structure; And, do not need to utilize again each spare part of pipeline connection, do not have the problem that the pipeline crushing causes impedance, can effectively reduce impedance; The utility model is one-body moldedly to make, and needn't offers more mould during fabrication again, can effectively reduce production costs.

For further understanding the purpose of this utility model and characteristics, enumerate specific embodiment now and be described with reference to the accompanying drawings as the back:
