Abstract

The utility model discloses a motorcycle oil-gas separator with comb-like filter element comprising a shell body with an inlet nozzle, a cover body with an outlet nozzle and a filter core. The shell body is fixedly connected with the cover body. A split cavity is formed in its inside, and the filter core is arranged in the split cavity. The filter core comprises a side plate, a separator and a baffle among which the number of the baffles is even, and their insides are connected with each other while the outside is provided with a comb. The side plate and the separator are compartmentally arranged in the quadrant composed by the baffle. The side plates are located on both sides of the baffle. The separator is located on the middle part of the baffle. The outer edge of the side plate and the separator is in accord with the cavity wall of the split cavity. The utility model is simple in structure and easy in implementation, solves the problem of great climate influence on original oil-gas separator with wider application and application effect support, eliminates oil evaporation waste, saves energy, simultaneously prevents exhaust directly entering the atmosphere, and effectively protects the environment.

Description

The motorcycle oil-gas separator of comb-like filter core

Technical field

The utility model relates to a kind of motorcycle, especially the motorcycle oil-gas separator of comb-like filter core.

Background technique

At present, during motorcycle engine work, imperfect combustion gas seals in the crankcase in the cylinder, generally directly drains in the atmosphere with crankcase inner engine oil vaporized gas.Owing to contain compounds such as CO, NO, HC in the waste gas, directly discharging does not reach European II standard, causes environmental pollution.And contained gaseous state machine oil is that engine operation is needed in the waste gas, directly discharges not only befouling environment, but also is a kind of waste of the energy.A kind of deaerator is arranged, be made up of housing, lid and filter core, fixedly connected between housing and the lid, it is inner to form a disengagement chamber, in this disengagement chamber tubular element is installed.It utilizes tubular element that the gaseous state machine oil in the waste gas is separated, and flows back to utilization again in the crankcase again.But under the north or arctic weather condition, because the sorting hole on the tubular element is too little, the water vapour in the waste gas freezes easily, the sorting hole on the element wall is stopped up, thereby influence its usability.

The model utility content

For solving above technical problem, the purpose of this utility model is to provide a kind of motorcycle oil-gas separator that is not subjected to the comb-like filter core of weather influence.

The technical solution of the utility model is as follows: a kind of motorcycle oil-gas separator of comb-like filter core, comprise the housing of bringing valve into, the lid and the filter core of band exhaust nozzle, fixedly connected between housing and the lid, disengagement chamber of its inner formation, in this disengagement chamber filter core is installed, its key is: described filter core comprises side plate, dividing plate and guide plate, and wherein the number of guide plate is an even number, their inboard is connected with each other, and the outside is provided with broach; At interval side plate and dividing plate are set in the quadrant that described guide plate is formed, its latus inframedium is positioned at the both sides of guide plate, and dividing plate is positioned at the middle part of guide plate, and the chamber wall of the outer of side plate and dividing plate and disengagement chamber matches.

Above-mentioned filter core is made of the guide plate that side plate, dividing plate and four outsides are provided with broach, and is vertical mutually between the two adjacent guide plates.

The structure of above-mentioned side plate and dividing plate is identical, and being central angle is the fan-shaped of 90 degree, and its right angle side is fixedly connected on respectively on the corresponding guide plate.

Spacing between above-mentioned adjacent fingers is 0.2～2mm.

The utility model is installed between motorcycle crankcase and the air-strainer, and its inlet and outlet mouth is communicated with crankcase and air-strainer respectively by rubber plastic pipe.When engine operation, imperfect combustion waste gas seals in the crankcase in the cylinder, mixes with the gaseous state machine oil that evaporates in the crankcase, forms mixed gas.When mixed gas passes through filter core, because side plate and dividing plate are provided with at interval, make the flow direction of mixed gas repeatedly change, waste gas is inhaled in the air-strainer under the suction function of air-strainer, and transferring Carburetor after the purification to provides fresh air; Gaseous state machine oil flows back to after condensing in the crankcase and utilizes again attached on side plate, dividing plate and the broach, even under the arctic weather condition, filter core can not stop up yet.

The beneficial effects of the utility model are: simple in structure, implement easily, it has solved original deaerator and has been subjected to the big problem of climatic impact, and not only applicable surface is wider, and using effect is secure.It had both eliminated the evaporation waste of machine oil, had saved the energy; Simultaneously prevented that again waste gas from directly entering in the atmosphere, protected environment effectively.
