Background

When the whole vehicle is tested on the road, the road condition and environment change frequently, and the state of engine oil of the engine is influenced by factors such as dust, carbon deposition impurities, operation conditions and the like. The real-time collection and monitoring of the engine oil temperature and pressure values of the engine are the most important part in the road test of the whole vehicle, the engine oil has the functions of lubricating, cleaning, cooling, buffering and the like on the engine, and the mechanical efficiency, the power and the service life of the engine are directly influenced by the engine oil temperature or the engine oil pressure. Therefore, the method has very important significance for evaluating and analyzing the performance of the engine in the whole vehicle environment and the working states of parts such as an oil pump or an oil cooler and the like by monitoring and analyzing the oil temperature and the pressure value in real time.

In the engine bench test, the engine is often operated at high revolution, full load and long time, or the revolution and the torque are alternated for a plurality of times in a short time in a certain test procedure, and personalized function tests result in that the engine working condition changes badly. During the operation of the engine on the test bed, the engine often fails in the test due to poor state or defects of parts. If the engine oil temperature and pressure values exceed the upper and lower limit values monitored by the test bed operating system, the engine oil temperature and pressure values can immediately trigger alarm to stop the engine, so that the purpose of protecting testers, the engine and the test bed is achieved. Also in the engine bench test, the evaluation of the performance quality of the engine, the state of an oil cooling system, whether the engine burns oil or not and the like by analyzing and calculating the oil temperature and pressure values under various working conditions plays a crucial role. The engine oil pressure switch of the original engine is arranged at the main oil duct of the cylinder body, and the measured temperature and pressure values are the most accurate. Because the engine can not be drilled in a destructive mode during testing, a tester can only collect the temperature and pressure values of engine oil at the position.

However, in the prior art, the tester widely adopts the adapter which is connected with the single-way or three-way connector at the installation position of the original machine pressure switch, and abandons the installation of the pressure switch, so that the function of adjusting the engine by the original machine pressure switch is lost during the test, the temperature and pressure values can not be acquired, the oil pressure switch can be simultaneously installed, the original function of the engine is maintained, and the requirement of the test is not met. The adapter of the single-way or three-way connector can only singly collect temperature or pressure values, so that the values need to be measured in turn, and the real-time test analysis efficiency is influenced.

The collection device is single in engine matching and poor in universality. The engine has the advantages of stronger and more compact design, limited surrounding space, and easy interference between parts when the collecting device is installed, which causes difficulty in assembly. The collection system has too many connecting parts, so that the parts needing sealing are too many, the installation is time-consuming and labor-consuming, and the risk of engine oil leakage exists.
