Engine oil external drive temperature control device connecting structure and temperature control system

Abstract

The invention provides an engine oil external drive temperature control device connecting structure and a temperature control system, and belongs to the technical field of automobile test equipment. The engine oil external drive temperature control device connecting structure comprises a frame type partition plate, an oil inlet connecting pipe and an oil outlet connecting pipe. The frame type partition plate is provided with a first connecting end face used for being connected with an engine air cylinder body and a second connecting end face used for being connected with an oil pan. An oil inlet connector and an oil outlet connector are arranged on the plate face of the frame-type partition plate, the oil inlet connecting pipe is connected to the inner side of the frame-type partition plate, and one end of the oil inlet connecting pipe is communicated with the oil inlet connector. The oil outlet connecting pipe is connected to the inner side of the frame type partition plate, and one end is connected with the oil outlet connector. According to the connecting structure, the engine oil external drive temperature control device and the engine oil way can be circularly connected without damaging the engine cylinder body and / or the oil pan, the integrity of the original engine oil way of the engine is kept, the structure is simple, assembling is convenient, the test period is effectively shortened, and the test accuracy is improved. The temperature control system can adapt to various test conditions and is high in universality.

Description

technical field [0001] The invention relates to the technical field of automobile testing equipment, in particular to a connection structure and a temperature control system of an engine oil external drive temperature control device. Background technique [0002] In the engine drag test, as the engine switches between different operating conditions, the heat emitted by combustion and the heat generated by friction are different, resulting in the temperature of the oil in the engine oil passage changing with the change of operating conditions. The oil temperature of the main oil passage is a very critical parameter, and it is necessary to precisely control the engine oil at different temperatures to obtain accurate test results to guide further optimization of the engine. [0003] In the related technology, the traditional oil temperature control method is to drill holes on the oil pan to set the oil inlet and outlet pipelines. The oil inlet and outlet pipelines are externall...

AI Technical Summary

Problems solved by technology

[0004] Using the test method in the related technology, when connecting the oil external drive temperature control device to the engine, each test needs to destroy the oil pan and cylinder block of the engine to drill holes, or trial-manufacture a connection with oil inlet and outlet pipelines The engine used for the test is complex and the test period is long

At the same time, the modification of the engine oil pan or cylinder block may also change the structure of the original lubrication system of the engine, which cannot reflect the actual working state of the oil lubrication system, resulting in a decrease in test accuracy.
