Overview

In a large mechanical system, the oil pan may not be the most prominent part, but its role is crucial. As an important part of the engine, the oil pan carries the important task of protecting the engine, and its existence is like the cornerstone and guardian of the car.

Function

The main function of the oil pan is to store and retain engine oil and provide lubrication for the engine. As the base of the engine, it carries the overall weight of the engine, and also has the effect of heat dissipation to help the engine maintain normal operating temperature. In addition, the oil pan can also help seal the crankcase and ensure that the pressure inside the engine is stable.

Structure

The oil pan is usually made of metal (such as aluminum alloy, steel, etc.) and has different shapes, depending on the type of engine it is in. Its surface is usually coated with anti-rust coating, and there are multiple grooves inside for storing oil. The oil pan is generally tightly integrated with the bottom of the engine to ensure that the oil will not leak.

Type

According to the engine type and design, the oil pan can be divided into various types. Common ones include flat-bottomed oil pan, semicircular oil pan and protective plate oil pan. Different types of oil pans have different characteristics and are suitable for different engine needs.
