Abstract
The utility model relates to a novel crankcase ventilation structure which comprises a crankcase oil and gas separator and a valve chamber cover oil and gas separator. The novel crankcase ventilation structure is characterized in that the crankcase oil and gas separator is connected with a crankcase, the gas discharge hole of the crankcase oil and gas separator is connected with a gas inlet pipe through a PCV (pollution control valve), one end of the valve chamber cover oil and gas separator is connected with gas compensation hole on a valve chamber cover, a gas discharge hole on the other end of the valve chamber cover oil and gas separator is connected with an air filter pipe through a two-way valve; and the oil and gas separation cavities of the crankcase oil and gas separator and the valve chamber cover oil and gas separator are internally provided with filter barriers, wherein the filter barriers are arrayed up and down in a staggered form. Because two oil and gas separators are arranged on an engine, the ventilation effect of the crankcase is strengthened.
Description
Technical field
The utility model relates to a kind of new type crank case aeration structure, belongs to a kind of closed crankcase ventilation system that is applicable to petrol engine.
Background technique
From protection to environment; The crankcase ventilation system of petrol engine all adopts the closed system of ventilation; Generally be integrated in valve chamber cover or the chain chamber cover cap, promptly the oil gas in the crankcase is through after being integrated in the deaerator separation in valve chamber cover or the chain chamber cover cap, and remaining oil gas gets into suction tude through the PCV valve; And a tonifying Qi hole is set in other positions of valve chamber cover or chain chamber cover cap, communicate through the pipeline after a two-way valve and the empty filter.But above-mentioned structure generally all is to have only a deaerator, for load and the higher petrol engine of rotating speed, has influenced the effect of Oil-gas Separation to a certain extent, causes the machine oil amount of carrying outside excessive.And owing to be limited by the restriction of spatial structure, it is also comparatively difficult that the scheme arrangement of increasing deaerator size is got up, and influenced the effect of crankcase ventilation system to a certain extent.
Summary of the invention
The purpose of the utility model provides a kind of new type crank case aeration structure, and it arranges two place's deaerators on motor, reinforcing crankshafts case ventilation effect.
The technological scheme of the utility model is achieved in that a kind of new type crank case aeration structure; By the crankcase oils gas separating device; Valve chamber cover place deaerator is formed; It is characterized in that: the crankcase oils gas separating device is connected crankcase, and crankcase oils gas separating device relief opening is connected with suction tude through the PCV valve, and valve chamber cover place deaerator one end covers the tonifying Qi hole with cyclinder head cover and is connected; Valve chamber cover place deaerator the other end relief opening is connected with empty filter back pipeline through two-way valve, staggered filtration is up and down arranged at a distance from retaining in the Oil-gas Separation chamber of crankcase oils gas separating device, valve chamber cover place deaerator.
The good effect of the utility model is simple in structure, convenient layout, reinforcing crankshafts case ventilation effect.
Description of drawings
Fig. 1 is the crankcase oils gas separating device structural drawing of the utility model.
Fig. 2 is the valve chamber cover place deaerator structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further: like Fig. 1, shown in 2; A kind of new type crank case aeration structure; By the crankcase oils gas separating device; Valve chamber cover place deaerator is formed; It is characterized in that: crankcase oils gas separating device 1 is connected crankcase, and crankcase oils gas separating device relief opening 3 is connected with suction tude through the PCV valve, and valve chamber cover place deaerator 2 one ends cover the tonifying Qi hole with cyclinder head cover and are connected; Valve chamber cover place deaerator the other end relief opening 4 is connected with empty filter back pipeline through two-way valve, staggered filtration is up and down arranged at a distance from retaining 5 in the Oil-gas Separation chamber of crankcase oils gas separating device 1, valve chamber cover place deaerator 2.
The oil gas of crankcase is through after being arranged in cylinder body and deaerator in the valve chamber cover separating, and gets into the pipeline after suction tude and empty the filter more respectively.After adopting this new type crank box ventilation system; Strengthened the ability that oil, gas separate greatly, the gas handling system of having avoided more oil gas to get into motor has reduced the influence of oil gas to throttle body; Avoid combustion-chamber deposit to a certain extent, reduced oil consumption.
