Abstract

The invention relates to the technical field of automobiles, in particular to a sealing structure of an engine and an automobile. The sealing structure of the engine comprises a cylinder cover, a cylinder body, a timing chain cover; the cylinder cover, the cylinder body and the timing chain cover are mutually assembled to form a sealing area; an outer eave is arranged in the cylinder cover, and the outer eave is close to the sealing area; and projection is projected in the direction of the cylinder cover pointing to the cylinder body, and the projection of the matching part of the cylinder cover and the cylinder body is located in the projection of the outer eave. According to the sealing structure of the engine and the automobile, the sealing effect of the combined surface of the cylinder body, the cylinder cover and the timing chain cover of the engine can be guaranteed, and the leakage phenomenon is prevented.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an engine sealing structure and an automobile. Background technique [0002] With the development of the economy and the gradual improvement of people's living standards, automobiles have become a common means of transportation in daily life. Among them, improving the quality and functionality of auto parts has become the key development direction of major manufacturers today. As an important part of the car, the engine acts as the power part of the car. Further, the sealing of the engine plays an important role in the normal operation of the engine, and the oil leaks at the joint surface of the engine block, cylinder head and timing chain cover. occur frequently. At present, the main solutions include the following: (1) increase the roughness of the sealing plane, (2) increase the rubber separation groove on the joint surface, (3) increase the rubber storage slope, and (4) ...
