Description

Oil pan, engine and vehicle

Technical Field

The present disclosure relates to the automotive field, and specifically, to an oil pan, an engine and a vehicle.

Background

At the end of the engine's combustion process, some of the unburned mixture leaks under high pressure from the piston rings into the crankcase, and this leakage is referred to in the industry as "blow-by". These blow-by gases escape from the crankcase into the atmosphere causing pollution. These blow-by gases are not removed and also dilute the oil in the crankcase, causing the oil to deteriorate and cause premature wear of engine components. The main function of a crankcase ventilation system is to conduct the exhaust gases away from the crankcase, and the breather is an important component of the ventilation system. When outdoor environment is low, hot oil vapor from the breather is accumulated when meeting cold, and is easy to freeze at the air outlet pipe of the breather, so that waste gas in the crankcase cannot be discharged in time. After long-time blockage, the oil level gauge can be popped up, oil leaks from the front oil seal and the rear oil seal of the crankcase, and the cylinder drawing, the tile drawing and the cylinder body breakdown of the engine can be seriously caused, so that the engine is scrapped.

In the related art, the breather outlet pipe is usually directly fixed somewhere in the engine to be communicated with the atmosphere. Still some engine plants solve the frozen scheme of respirator outlet duct and mainly have the method such as increase the heat preservation cover, set up the box that prevents frostbite, utilize resistance heating device, and this type of mode needs to increase extra device, and the commonality is poor, needs great installation space, increases the assembly link again simultaneously, has reduced assembly efficiency.

Furthermore, in the following description, when referring to the figures, the same reference numbers in different figures denote the same or similar elements, unless otherwise explained.

According to an embodiment of the present disclosure, there is provided an oil pan, as shown in fig. 1 and 2, the oil pan includes a housing 1 and a box-shaped structure 10 formed at a side of the housing 1, the box-shaped structure 10 may have a bottom opening, and includes a side plate 11 and a top plate 12 connected to a top of the side plate 11, and the top plate 12 may be opened with a through hole 121 through which a breather outlet pipe 2 passes. Namely, after the respirator air outlet pipe 2 extends downwards from the top of the box-shaped structure 10, the air exhausted from the air outlet end of the respirator air outlet pipe is exhausted to the atmosphere from the bottom opening of the box-shaped structure 10.

Through the technical scheme, the breather air outlet pipe 2 is arranged on the oil pan shell 1, so that the heat of engine oil in the oil collecting position of the oil pan can be utilized to the maximum extent to increase the local temperature of the air outlet at the tail end of the breather air outlet pipe 2. The design of box-like structure 10 can be used for fixed respirator outlet duct 2, and lateral plate 11 and the roof 12 at top all around box-like structure 10 also can form a relative confined space, and this space can further keep warm to the terminal gas outlet of respirator outlet duct 2 to prevent the problem of the engine damage that leads to of respirator outlet duct 2 freezing under the severe cold environment. Simultaneously, the design of installing respirator outlet duct 2 on the oil pan need not increase extra heating device, saves auto parts's installation space and assembly link, and the commonality is high, and applicable in all open crankcase ventilation systems to can effectively improve assembly efficiency.

It should be noted that the bottom opening of the box-like structure 10 is for letting the gas exhausted from the respirator outlet pipe 2 flow into the atmosphere, the size of the bottom opening of the box-like structure 10 has no specific requirement, and may be a full opening without a bottom plate as shown in fig. 2, or may be a partial opening with only a part of the bottom plate removed, as long as the gas can be exhausted smoothly, and the present disclosure does not make any limitation on the specific form of the bottom opening portion of the box-like structure 10.

Further, as shown in fig. 3, a side of the box-like structure 10 close to the housing 1 is formed with a groove 13 recessed toward the inside of the housing 1 for accommodating the lower end of the respirator outlet duct 2, the groove 13 is designed to allow the respirator outlet duct 2 to receive more temperature from the inside of the housing 1, and the groove 13 can further limit the position of the respirator outlet duct 2 to prevent the lower end of the respirator outlet duct 2 from swinging around during the driving of the vehicle.

Further, as shown in fig. 3, the groove 13 may be configured as a semi-cylindrical groove matching with the shape of the breather outlet pipe 2, the shape matching design may better limit the lower end of the breather outlet pipe 2, and at the same time, the contact area between the breather outlet pipe 2 and the side wall of the oil pan may be increased as much as possible, so as to better transfer the heat of the oil pan to the breather outlet pipe 2. It should be noted that the aforementioned "contact area" does not mean that the respirator outlet tube 2 fits completely into the groove 13, but a certain gap is left between the two.

Further, as shown in fig. 1 and 3, the radius of the arc of the groove 13 may be the same as the radius of the through hole 121, and the arc surface of the groove 13 may be located right below the partial arc of the through hole 121, and the design of the through hole 121 corresponding to the groove 13 may enable the breather outlet tube 2 to vertically extend into the box-shaped structure 10 through the through hole 121 and then be just accommodated in the groove 13, so that the warming effect may be optimal.

Or according to another embodiment, the side plate 11 is fastened to the side wall of the housing 1, that is, the side wall of the housing 1 is directly formed as the inner side surface of the box-shaped structure 10, and the side wall of the housing 1 is directly recessed toward the oil pan cavity to form the groove 13. The design of the single-layer inner side surface can reduce heat transfer loss as much as possible and can adapt to more extreme and high-cold environments.

In the embodiment of the present disclosure, as shown in fig. 2 and 3, the oil pan may further include a stopper 14 disposed at the bottom of the box-like structure 10 and partially or entirely located directly below the groove 13. The stop portion 14 can be a stop piece formed on the side wall of the housing 1 or the inner side plate of the box-like structure 10. For example, the stopping portion 14 may also be a boss integrally formed on the sidewall of the casing 1 or provided on the inner side plate of the box-like structure 10 and protruding toward the opposite direction inside the cavity of the casing 1, so as to block the outlet of the respirator outlet pipe 2, and the boss is of a solid structure. Under the condition that the bottom of the box-shaped structure 10 is fully opened or the opening is too large, the design of the stopping portion 14 can assist in keeping the temperature inside the box-shaped structure 10, and can prevent impurities such as mud, rainwater and the like outside the vehicle in the running process from splashing to the tail end outlet of the respirator air outlet pipe 2 to cause unnecessary blockage to the pipe opening.

On the basis of the scheme, the engine comprises an engine box body 3, an oil pan arranged at the lower end of the engine box body 3, and a breather air outlet pipe 2, wherein the lower end of the breather air outlet pipe 2 extends into a box-shaped structure 10.
