A diesel engine oil temperature regulation system

Abstract

The invention provides a diesel engine oil temperature adjusting system. The diesel engine oil temperature adjusting system comprises an oil pump, an oil filter, an automatic temperature regulator and an engine oil heat exchanger which are communicated in sequence. The automatic temperature regulator and the engine oil heat exchanger are respectively communicated with a diesel engine main oil way. When the temperature of engine oil entering the automatic temperature regulator reaches to the set standard temperature, a pipeline between the automatic temperature regulator and the inlet end of the engine oil heat exchanger is cut off by the automatic temperature regulator. When the temperature of the engine oil entering the automatic temperature regulator is lower than or higher than the set standard temperature, the pipeline between the automatic temperature regulator and the inlet end of the engine oil heat exchanger is conducted. By means of the diesel engine oil temperature adjusting system, the temperature, the viscosity and other indexes of the engine oil entering the diesel engine main oil way can be controlled within the appropriate allowed range, the requirements for lubricating and cooling the diesel engine are met, the safety and reliability of work of the diesel engine are improved, and the diesel engine oil temperature adjusting system has the obvious advantages of being simple in structure, low in implement cost and the like.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a diesel engine oil temperature adjustment system. Background technique [0002] The oil in the existing diesel engine is directly sucked into the oil pump from the oil pan, and the oil pump converts the sucked oil into pressure oil with a certain pressure, and then enters the oil filter. The oil outlet pipe on the cleaner is assembled into the oil heat exchanger, and finally enters the main oil passage of the diesel engine, so as to lubricate and cool the corresponding parts of the diesel engine, so as to ensure the reliable and continuous operation of the diesel engine. [0003] However, since the cooling medium of the oil heat exchanger is the cooling water from the intercooler, when the diesel engine is started or under low load operation, the temperature of the cooling water entering the oil heat exchanger is low, and the temperature of the oil is also low, so , the ...

Problems solved by technology

[0003] However, since the cooling medium of the oil heat exchanger is the cooling water from the intercooler, when the diesel engine starts or operates at low load, the temperature of the cooling water entering the oil heat exchanger is low, and the temperature of the oil is also low, so , the cooling water cannot heat the temperature of the engine oil to the appropriate temperature required by the diesel engine, which will cause the high viscosity of the engine oil caused by the low temperature of the engine oil. These low-temperature and high-viscosity engine oils will directly enter the main oil passage of the diesel engine without further treatment. It not only affects the flow performance of the engine oil, but also deteriorates the lubrication condition of the diesel engine

When the diesel engine is working under high load or for a long time, the temperature of the engine oil is high, and the temperature of the cooling water entering the oil heat exchanger is also high. Therefore, the cooling water cannot lower the temperature of the engine oil, resulting in the viscosity of the oil The oil with high temperature and low viscosity will directly enter the main oil passage of the diesel engine without further treatment, resulting in a decrease in the carrying capacity of the engine oil and deterioration of the lubrication and cooling conditions of the diesel engine, which is not conducive to the reliable and continuous operation of the diesel engine
