Thermal shock test device and thermal shock test method for diesel engine

Abstract

The invention discloses a thermal shock test device for a diesel engine, wherein the diesel engine is connected to a lower computer measurement and control system; the lower computer measurement and control system is connected to a host computer monitoring system; the upper computer monitoring system sets a running command and a temperature range command of the diesel engine, and sends the commands to the lower computer measurement and control system; the lower computer measurement and control system runs the diesel engine according to the commands of the upper computer monitoring system, measures the operating parameters and temperature parameters of the diesel engine in real time during the operation, and transmits the parameters to the upper computer monitoring system; the upper computer monitoring system monitors the ambient temperature parameters, determines the ambient temperature parameters in combination with the operating parameters and temperature parameters of the diesel engine, and feeds the result back to the lower computer measurement and control system; and the lower computer measurement and control system adjusts the operation of the diesel engine according to the feedback information, and balances the current temperature range. The thermal shock test device for a diesel engine has a good application prospect in the thermal impact test of the diesel engine.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a diesel engine thermal shock test device and method. Background technique [0002] my country is a big country in automobile use and automobile manufacturing, with an average of one automobile for every three people. However, due to the late start of my country's automobile industry, the automation level of engine performance testing is still relatively low, and there is currently a lot of room for improvement in many aspects. As the heart unit of a car, the engine's superior performance determines the life span of the entire car. Compared with gasoline engines, the test platform of diesel engines requires more power, and the corresponding working conditions will become more complex, and the requirements for mechanical load and thermal load will be higher. [0003] In addition, my country has a vast territory, and the climatic conditions vary greatly between the north a...
