Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
The utility model embodiment provides a kind of air inlet pipeline, shown in Figure 1, described air inlet pipeline comprises body 1, joint body 1 being provided with the first interface 2 be connected with air cleaner assy, the second interface 3 be connected with engine assembly and the 3rd interface the 4, three interface 4 be connected with crankcase ventilation system and body 1 is provided with oil-gas separation chamber 5.The air inlet pipeline that the utility model provides can the ventilation of carrying oil gas in crankcase when entering into oil-gas separation chamber 5 by the 3rd interface 4, make the oil gas oil droplet that congeals into rest in oil-gas separation chamber 5, ventilate then directly enter into air inlet pipeline body in be delivered to engine assembly.Compared with prior art, the Oil-gas Separation of carrying in the ventilation in crankcase can be gone out by the air inlet pipeline that the utility model provides, and avoids oil gas to cause motor cisco unity malfunction along with ventilation enters into engine assembly, improves the stability of engine assembly.
Preferably, shown in Figure 2, oil-gas separation chamber 5 is the ring-shaped cavity be connected with the outer wall of body 1, and the 3rd interface 4 is located on the sidewall of ring-shaped cavity, the top of ring-shaped cavity offers multiple through hole, and the space be positioned on through hole is communicated with the air flow channel of body 1.When the ventilation in crankcase enters into oil-gas separation chamber 5 from the 3rd interface 4, because the temperature in oil-gas separation chamber 5 is lower, oil gas in ventilation can become liquid from gaseous state, thus stay in oil-gas separation chamber 5, ventilate and then can flow in the air flow channel of body 1 from the through hole the cavity top of oil-gas separation chamber 5.Oil gas can be avoided to cause motor cisco unity malfunction along with ventilation enters into engine assembly, improve the stability of engine assembly.
Preferably, shown in Fig. 3 and Fig. 4, a sidewall of oil-gas separation chamber 5 is connected with the outer wall of body 1, and joint is provided with air flow channel, and the 3rd interface 4 is located on the sidewall of the another side of oil-gas separation chamber 5.The place different from upper a kind of side of enforcement is, in present embodiment, oil-gas separation chamber 5 is only simultaneously connected with the outer wall of body 1, instead of encloses around body 1 one, and can reduce the shared volume of body 1 assembly like this, be the configuration section save space of car load inside.Based on same principle, when the ventilation in crankcase enters into oil-gas separation chamber 5 from the 3rd interface 4, because the temperature in oil-gas separation chamber 5 is lower, oil gas in ventilation can become liquid from gaseous state, thus stay in oil-gas separation chamber 5, ventilate and then can enter the air flow channel of body 1 from the air flow channel of oil-gas separation chamber 5 with body 1 joint.Oil gas can be avoided to cause motor cisco unity malfunction along with ventilation enters into engine assembly, improve the stability of engine assembly.
Preferably, shown in Fig. 2 and Fig. 3, oil-gas separation chamber 5 is also provided with the position of the 4th interface the 6, four interface 6 lower than the 3rd interface 4.The main purpose arranging the 4th interface is to be guided away by the fluid retained in oil-gas separation chamber 5, and therefore, the position of the 4th interface 6 lower than the 3rd interface 4, will enable in the easier inflow of fluid the 4th interface 6.
Preferably, shown in Figure 2, the bottom of oil-gas separation chamber 5 is for being obliquely installed, and on bottom, close 4th interface 6 side is lower than the side near the 3rd interface 4.The object that this kind is arranged is to make the flowing of the fluid easier direction towards the 4th interface 6, can make that fluid is easier discharges from the 4th interface 6.
Preferably, in order to enable the fluid in oil-gas separation chamber 5 recycle, the 4th interface 6 being connected with the intake manifold of motor or being connected with engine lube system return line.To be connected with intake manifold, if the 4th interface 6 is connected with the intake manifold of motor, when closed throttle, negative pressure in intake manifold increases, pressure in such oil-gas separation chamber 5 will be greater than the pressure in intake manifold, fluid flow in intake manifold from the 4th interface 6 under the effect of the pressure, carries out after atomization mixes with air, entering in motor and burning in intake manifold.Further, intake manifold or return line is flowed in order to control fluid better, the pipeline that can be communicated with the 4th interface 6 in intake manifold or return line arranges one-way conduction structure (such as one-way conduction valve), this one-way conduction structure also accessible site, in air inlet pipeline interface position, or to be integrated on intake manifold or return line.
Preferably, in order to save operation and cost, oil-gas separation chamber 5 is one-body molded with air inlet pipeline.Or in order to ensure the fixing stability between oil-gas separation chamber 5 and air inlet pipeline, oil-gas separation chamber 5 is fixed on air inlet pipeline by welding or being spirally connected.
The utility model embodiment provides a kind of engine charge pipe assembly, is provided with air inlet pipeline as above.The engine charge pipe assembly that the utility model provides can the ventilation of carrying oil gas in crankcase when entering into oil-gas separation chamber 5 by the 3rd interface 4, make the oil gas oil droplet that congeals into rest in oil-gas separation chamber 5, ventilate then directly enter into air inlet pipeline body in be delivered to engine assembly.Compared with prior art, the Oil-gas Separation of carrying in the ventilation in crankcase can be gone out by the air inlet pipeline that the utility model provides, and avoids oil gas to cause motor cisco unity malfunction along with ventilation enters into engine assembly, improves the stability of engine assembly.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
