A diesel engine cooling system and lubrication system integrated module

Abstract

The invention discloses a cooling system and lubricating system integration module for a diesel engine. The cooling system comprises a module shell. An engine oil cooler, an engine oil filter and a water pump are arranged on the module shell. A water way and an oil way are arranged in the module shell. A cylinder block mounting face for being mounted on an engine cylinder block is arranged on the module shell. An oil inlet a and an oil outlet a are formed in the cylinder block mounting face. An inlet check valve is arranged on the oil inlet a. An outlet check valve is arranged on the oil outlet a. In this way, when the engine is shut down, engine oil in the module cannot flow back into the engine cylinder block; and when the engine is started again, it is not necessary to make the module be filled with the engine oil in advance, and the time of the engine oil entering the engine cylinder block is shortened, so that engine movement friction components can be lubricated in time, the operating reliability of the engine is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an integrated module of a cooling system and a lubricating system of a diesel engine. Background technique [0002] Modularization has become one of the important trends in the design and manufacture of diesel engines due to its advantages of fast market response, short development cycle, and cost savings, and it can also be used for collinear production of engines with different displacements and different structures. In addition, the maintenance efficiency of the engine has also been improved, and the maintenance cost has also been significantly reduced. The important thing is that modularization can minimize the number of parts, reduce the failure rate of parts, simplify the structure of the engine, and reduce the weight of the engine. [0003] In the traditional engine design, the water pump, oil filter, and oil cooler usually adopt a separate structure. The disadvantages...

Problems solved by technology

[0003] In the traditional engine design, the water pump, oil filter, and oil cooler usually adopt a separate structure. The disadvantages are: scattered structure, large volume, complex pipeline, and many fault points

Moreover, after the existing engine is stopped, when it is restarted, the moving friction parts in the engine cannot be lubricated in time, which affects the working reliability of the engine.
