Abstract

The invention provides an oil inlet sealing structure of a diesel engine. The oil inlet sealing structure comprises a cylinder cover, an oil injector, a guide barrel body, a cam bearing frame, an oil inlet tube, a sealing bush, an oil injector pressing thread sleeve, an oil inlet tube pressing thread sleeve and an oil return head. According to the oil inlet sealing structure of the diesel engine, through the reasonable layout between the oil inlet tube and the cam bearing frame, the guide barrel body and the cylinder cover and the reasonable application of the sealing bush and sealing rubber rings, the reliable sealing of diesel oil and engine oil between the oil injector and the guide barrel body, the guide barrel body and the cylinder cover, the guide barrel body and the oil inlet tube, the oil inlet tube and the cam bearing frame is achieved while the height of an entire engine is reduced.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, in particular to an oil inlet sealing structure of a diesel engine. Background technique [0002] The side oil inlet hole of the fuel injector of diesel engine is mostly processed on the cylinder head, and the oil inlet pipe is sealed between the oil inlet pipe and the fuel injector by tightening the compression sleeve on the cylinder head. This structure has good sealing reliability and less sealing links, but this structure is mostly used in diesel engines with sufficient layout space on the cylinder head. When the diesel engine develops towards high volumetric power and high-quality power, the height of the cylinder head is reduced. Such a structure becomes a difficulty in the arrangement of the engine. Contents of the invention [0003] In view of this, the present invention aims to propose an oil inlet sealing structure for a diesel engine, which can achieve reliable sealing betwee...
