Abstract

The invention provides an engine heat balancing performance bed tester and an engine heat balancing performance bed testing method, which belong to the field of engine heat balancing technology. The tester provided by the invention comprises an engine bed system, an external cooler and a signal feedback controller; the external cooler is used for cooling built-in cooling devices of a currently tested engine; the signal feedback controller is used for presetting an engine temperature threshold and testing time, monitoring the temperature of the currently tested engine in real time, ordering the engine bed system to control the external cooler to regulate the cooling speed of the built-in cooling devices of the currently tested engine when the temperature of the currently tested engine reaches the preset engine temperature threshold and evaluating the heat balancing performance of the currently tested engine according to the temperature data of the currently tested engine within the testing time. The testing scheme provided by the invention can conveniently and efficiently carry out real-time on-line tests on the engine heat balancing performance of automobiles.

Description

technical field [0001] The invention relates to the technical field of engine heat balance, in particular to a bench test device and method for engine heat balance performance. Background technique [0002] The heat balance performance of an automobile engine is an important index to balance the performance of the whole vehicle, and it is also an important parameter to measure the quality of the automobile. It has been proved by practice that the temperature of the coolant and engine oil of the automobile engine is easy to exceed the maximum allowable temperature under the condition of thermal balance. When the temperature of the coolant and engine oil exceeds the maximum allowable temperature, the phenomenon of engine explosion and excessive wear will occur. The service life of automobile is reduced, and the driver's life safety also has serious hidden danger. Therefore, the heat balance performance of automobile engine is an important index to evaluate the reliability and...
