Oil filter and front cover integrated module

technical field

The utility model belongs to the technical field of engines, in particular to an integrated module of an engine oil filter and a front end cover.

Background technique

Most of the existing engine oil filters are independently installed, and bolts are generally used to fix the oil filter on the engine cylinder block or on a separate oil filter seat. At the same time, in order to prevent oil leakage on the joint surface, gaskets or rubber sealing rings are generally used to ensure the sealing effect. This leads to more parts in the engine lubrication system, and the greater the number of parts, the greater the risk of failure.
