Description

A diesel engine oil pan

technical field

The utility model relates to a diesel engine oil pan.

Background technique

The oil pan in a diesel engine is an important part in the lubrication system, which plays the role of crankcase seal and oil storage. During the operation of the diesel engine, the engine oil circulates in the diesel engine, and the oil pan collects and stores the engine oil that flows back from the friction surfaces of the diesel engine. From the perspective of heat dissipation, the oil pan needs to have a large enough external area to facilitate heat dissipation and prevent oil oxidation. From the material point of view, aluminum metal materials with low density are selected and cast to reduce the weight of the oil pan, and the surface is required to be smooth and free of debris. A stable oil baffle is installed inside the oil pan to avoid oil level shock caused by engine vibration. An oil dipstick is installed on the side of the oil pan, and the dipstick is used to measure the amount of oil. The oil drain screw plug is installed at the lowest part of the oil pan, and the oil drain screw plug is used to change and drain the engine oil. At the same time, the oil pan needs to take into account the installation space and the matching of the oil return pipe of other related parts, and has a complex shape. Therefore, it is difficult to design a reasonable oil pan; most of the existing oil pans have the defects of large floor space and poor heat dissipation.

Utility model content

In order to solve the above problems, the utility model proposes a diesel engine oil pan, which has good sealing and stability and is suitable for diesel engines with small installation space.

In order to achieve the above object, the utility model adopts the following technical solutions:

An oil pan for a diesel engine, including a housing, on which there are bolt holes connected to the crankcase, several bosses are arranged on both sides of the housing, one side of the boss is provided with an oil dipstick installation hole, and the other side The boss is provided with the oil return hole of the supercharger and the oil return hole of the oil-gas separator, the bottom of the casing is provided with an oil discharge screw plug hole, and the inside of the casing is provided with an oil stabilizing baffle.

The casing is connected to the oil return pipe of the supercharger through the oil return hole of the supercharger.

The housing is connected to the oil return pipe of the oil and gas separator through the oil return hole of the oil and gas separator.

The boss is provided with a flange surface of the oil return hole of the supercharger, and the flange surface matches the flange of the oil return pipe of the supercharger.

The boss is provided with a flange surface of the oil return hole of the oil-gas separator, and the flange surface matches the flange of the oil return pipe of the oil-gas separator.

The shell is formed by low-pressure casting of the oil sump, and the inner surface is sandblasted.

A spare reserved hole is arranged on the boss.

The working principle of the utility model is:

There are several bosses on the shell, and the bosses are designed to reduce the weight of the oil pan as much as possible, which can effectively increase the surface area of the oil pan, increase the heat dissipation of the oil, and prevent the oxidation of the oil; the bosses are reasonably arranged for each oil return hole , easy to install, compact structure, and the reserved hole on the top retains the blank state, which plays a role in the design of future model changes; the oil pan is equipped with a stabilizing oil baffle to avoid oil level shock caused by engine vibration , which is conducive to the deposition of debris.

The utility model has the beneficial effects of providing an oil pan with good sealing and stability for a diesel engine with a small installation space, which has a simple structure, saves space, is convenient for industrial production, and has economic prospects.
