Abstract

The invention relates to a lubricating oil passage of an engine cylinder body assembly, which adopts an arrangement mode comprising an oil collector, an oil pump, an oil pump outlet pipe, an oil cooler, an oil filter, a main oil passage, an inclined oil passage, a cylinder cover oil passage, a pressure feedback oil passage and other auxiliary oil passages. The arrangement mode has the following characteristics: (1) the arrangement difficulty of the oil passages of a cylinder body is effectively reduced by using the oil pump outlet pipe; (2) the oil filter and the oil cooler adopt a modular design; (3) two oil passages arranged on the cylinder body are led to the cylinder cover, thereby reducing the pressure drop and improving the pressure response speed; and (4) the pressure feedback oil passage of oil is arranged so that the oil pump can adjust the trans-emission amount in time according to the pressure of the main oil passage.

Description

technical field [0001] The invention belongs to the technical field of automobile structure, and in particular relates to an arrangement method of lubricating oil passages of an engine cylinder block assembly. Background technique [0002] In the traditional oil passage arrangement, after the lubricating oil flows out from the oil pump, it has to pass through a long oil passage arranged in the cylinder body before it can flow into the machine filter. Moreover, the cylinder head lubricating oil comes entirely from the main oil passage of the cylinder block. That is, the lubrication of the cylinder head and the cylinder block is a series relationship. In addition, the traditional oil passage layout has no oil pressure feedback design. [0003] In order to ensure the normal operation of the engine, it is necessary to provide sufficient, clean and suitable lubricating oil for all parts of the engine, such as main journal, connecting rod journal, timing chain, camshaft, etc. D...
