Engine test stand system and test method

Abstract

The invention provides an engine test stand system and test method. The engine test stand system comprises a test stand cooling water pipeline, a test stand engine oil pipeline, a test stand fuel oil pipeline, an industrial control computer, a dynamometer and a current signal generator. The test stand cooling water pipeline and the test stand engine oil pipeline are respectively provided with a constant temperature control unit. The test stand fuel oil pipeline is provided with a fuel consumption meter and a constant temperature control unit. The dynamometer, the current signal generator and the fuel consumption meter are electrically connected with the industrial control computer. The engine test method comprises the steps that power parameters, rotating speed parameters and the fuel consumption level of an engine are monitored in real time through the dynamometer, the current signal generator and the fuel consumption meter, and unified control and management are performed through the industrial control computer. System construction is easy and operation is simple, and the engine test result has high reliability so that test cost of engine testing can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of engine testing, in particular to an engine test bench system and a test method. Background technique [0002] The qualification test of the engine is mainly to check whether the engine speed, power and fuel consumption parameters meet the design requirements. The detection of the engine involves many test parameters, and various test parameters are associated with certain test conditions. Therefore, the performance test for the engine is very complicated. [0003] Existing qualification testing for engines is usually carried out independently, with a low degree of automation and complicated operations. Therefore, it is not easy to control the collection of various test parameters and the monitoring of test conditions in the test, which leads to engine testing. It requires a lot of manpower and material resources, and the test cost is high. Moreover, the stability and accuracy of the engine test cannot be...

[0003] Existing qualification testing for engines is usually carried out independently, with a low degree of automation and complicated operations. Therefore, it is not easy to control the collection of various test parameters and the monitoring of test conditions in the test, which leads to engine testing. It requires a lot of manpower and material resources, and the test cost is high. Moreover, the stability and accuracy of the engine test cannot be guaranteed. Therefore, the reliability of the engine test results cannot be guaranteed.
