Oil system of a high-power diesel engine

Abstract

The invention provides an engine oil system of a high-power diesel engine. The engine oil system comprises an engine oil pump, an engine oil priority valve, centrifugal engine oil filters, superchargers, supercharger filters and pressure regulating valves. The engine oil pump is connected and communicated with the centrifugal engine oil filters, the superchargers are connected and communicated with the supercharger filters via the pressure regulating valves, an engine oil pump first oil outlet tube on the engine oil pump is connected and communicated with an engine oil priority valve main oil passage inlet in the engine oil priority valve, an engine oil pump second oil outlet tube is connected and communicated with an engine oil priority valve auxiliary oil passage inlet in the engine oil priority valve, a certain interface in the engine oil priority valve is connected and communicated with a cooling piston oil passage of the diesel engine, and the certain interface extends from the engine oil priority valve to the cooling piston oil passage. The engine oil system has the advantages that the self engine oil filter ability of the diesel engine can be improved, engine oil consumption of the system can be reduced, and the pressure of the integral engine oil system can be reliably controlled; the engine oil system is reasonable and compact in integral structure and is favorable for guaranteeing the dynamic property, the economical efficiency, the reliability and the durability of the diesel engine.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to an engine oil system of a high-power diesel engine. Background technique [0002] The oil system of a diesel engine is an important part of a diesel engine. The oil system plays a role in lubricating, conducting heat, cleaning, sealing, and preventing rust on the parts of the diesel engine, so that the moving units of the diesel engine can be fully lubricated, thereby reducing friction loss and reducing parts. wear to ensure the power, economy, reliability and durability of the diesel engine. [0003] The existing diesel engine oil system is mainly composed of oil pump and its inlet and outlet pipe assembly, oil centrifugal oil filter, supercharger filter, safety valve, gear lubrication piping system, left and right supercharger lubricating oil pipe assembly, pressure regulating valve And the oil pipeline and so on. The specific layout of the system is as follows: (1) Th...

AI Technical Summary

Problems solved by technology

Since there are only two centrifugal oil filters for engine oil, the self-filtering ability of the entire engine oil system is poor; the safety valve is a safety valve with an opening pressure value, which is not conducive to reducing the oil consumption of the diesel engine; The lubricating pipelines of the rocker shaft and the fuel injection cam are designed outside the engine body, which makes the structure of the diesel engine oil system scattered and not compact, and takes up external space; in addition, the filtration accuracy of the supercharger filter is 25 microns, which is not conducive to The lubrication of the supercharger reduces the service life of the supercharger
