Problems solved by technology

[0002] At present, people pay more and more attention to the quality of the air environment inside the car. In order to prevent the crankcase exhaust gas from being discharged into the atmosphere, the crankcase exhaust gas is directed to the appropriate position of the intake pipe through the connecting pipe, and returned to the cylinder for re-combustion, which can reduce exhaust pollution. Also improve the economy of the engine To prevent excessive crankcase pressure, prolong the service life of engine oil, reduce wear and corrosion of parts, prevent engine oil leakage, meet increasingly stringent emission requirements and improve economy, the check valve of the crankcase ventilation system of the engine At present, there are mainly two kinds of external connection and integrated valve chamber cover: the external connection is to arrange the one-way valve in the middle of the pipeline and connect it with a hose. This arrangement is more complicated and increases the cost and the risk of pipeline leakage; the other is The one-way valve is integrated on the valve chamber cover. Although this method makes the pipeline layout simple, the one-way valve always works in a high-temperature environment, and the service life is greatly affected by the environment.

Embodiment 1

[0027] An intake manifold device with integrated crankcase ventilation, the structure of which is as follows Figure 1 ~ Figure 3 As shown, it includes the intake manifold body 1, the baffle plate 2 and the sealing umbrella valve 3, and the intake manifold body 1 is composed of the matched manifold upper piece and the manifold lower piece assembled and connected to form the intake manifold body In 1, a pressure stabilizing chamber and a vacuum chamber that are not connected to each other are formed. Among them, the upper plate of the manifold is opened with a ventilation interface connected with the pressure stabilizing chamber, and the intake manifold body 1 is opened with a ventilation interface connected to the crankcase. 2 is set at the ventilation interface, and on the baffle 2 there is also a vent hole connecting the intake manifold body 1 and the crankcase, the sealing umbrella valve 3 is movably installed on the baffle 2, and the sealing umbrella valve 3 includes a conn...

Embodiment 2

[0030] Compared with Embodiment 1, most of them are the same, except that in this embodiment, at least one sealing ring is provided on the edge of the valve cover from the inside to the outside, and the baffle plate 2 is provided with a sealing groove corresponding to the sealing ring. There are multiple holes, which are evenly distributed in the area surrounded by the innermost sealing groove centered on the mounting hole.

Abstract

The invention relates to an air intake manifold device integrated with crankcase ventilation. The air intake manifold device comprises an air intake manifold body, a baffle and a sealing umbrella valve. The air intake manifold body is provided with a ventilation connector connected with a crankcase. The baffle is arranged at the ventilation connector and is further provided with ventilation holesused for communicating the air intake manifold body with the crankcase. The sealing umbrella valve is movably installed on the baffle. Compared with the prior art, the air intake manifold device integrated with crankcase ventilation has the advantages of being long in service life, safe, reliable, good in sealing property, low in cost and the like.
