Embodiment

[0025] Such as figure 1As shown, the present invention includes an engine oil tank 1, a temperature sensor 2, a solenoid valve 3, an oil suction pump 4, a cooler 5, a filter 6, a trigger system 7, an oil outlet pipe 8, an oil inlet pipe 9, a logic gate control system 10, and a pulse width Modulation processing system 11 . In order to be able to control the temperature of the engine oil, the oil inlet of the cooler 5 is connected with the engine oil tank 1 through the oil outlet pipe 8, so that the high temperature engine oil in the engine oil tank 1 can be input into the cooler 5 through the oil outlet pipe 8. And the oil outlet of cooler 5 is then connected with engine oil tank 1 by oil inlet pipe 9, so that the machine oil cooled by cooler 5 can be transported back in the engine oil tank 1 by oil inlet pipe 9. The solenoid valve 3 is arranged on the oil outlet pipe 8 , and the oil suction pump 4 is arranged on the oil outlet pipe 8 and is located between the solenoid valve ...

Abstract

The invention discloses an engine oil constant-temperature automatic control system based on pulse width modulation processing. The engine oil constant-temperature automatic control system based on pulse width modulation processing mainly comprises an engine oil tank (1), a temperature sensor (2), an electromagnetic valve (3), an oil suction pump (4), a cooler (5), a filter (6), a trigger system (7), an oil outlet pipe (8), an oil inlet pipe (9), a logic gate control system (10) and a pulse width modulation processing system (11). According to the engine oil constant-temperature automatic control system based on pulse width modulation processing, signals that are output by the temperature sensor are processed by means of the pulse width modulation processing system, the processed signals are quite stable, and thereby, the phenomena of frequent starting and halting of the constant-temperature automatic control system can be avoided.

Description

technical field [0001] The invention relates to the field of engine testing, in particular to an engine oil constant temperature automatic control system based on pulse width modulation processing. Background technique [0002] People's requirements for the reliability, safety and greenness of automobiles are constantly increasing, and the engine is the heart of the automobile, and its technical level directly affects its performance indicators such as power, economy, and emissions. The frequency of engine failure It is also the highest. The engine comprehensive performance test is the main means to judge the technical condition of the engine, and it is also an important part of the vehicle inspection and maintenance work. Therefore, the engine performance test has been paid more and more attention by people. [0003] When the engine is tested, all moving parts need oil lubrication, so all engines are equipped with a lubrication system. Through the oil pump, the high-press...
