Problems solved by technology

[0002] In the existing technology, the oil inlet and outlet pressures are not precisely controlled during the engine test. With the improvement of test standards, the performance and emission indicators are more stringent, and the impact of inaccurate control of the oil inlet and outlet pressures is no longer satisfactory Test method requirements
In addition, with the upgrading of fuel pump products, the new fuel pump also has very high control requirements for the oil inlet and return pressure. If the pressure is too high, the fuel pump product will be damaged (the camshaft seal ring of the diesel lubricated fuel pump is broken)

Abstract

The present invention relates to an engine bench oil inlet and return pressure regulation device. The device comprises a mobile car frame, the mobile car frame is provided with an oil inlet pressure regulation valve and an oil return pressure regulation valve, two ends of the oil inlet pressure regulation valve are connected with an inlet oil electric fuel pump, one end of the oil inlet pressure regulation valve is connected with an oil inlet pressure sensor, the two ends of the oil return pressure regulation valve are connected with an oil return electric fuel valve, and one end of the oil return pressure regulation valve is connected with an oil return pressure sensor. The engine oil supply channel and the pressure of the oil return channel are regulated to ensure the working of the engine in the controlled oil quantity interval and avoid that too large or too small pressure causes unstable working condition of the engine, reduced performances and deterioration of emissions.

Description

technical field [0001] The invention belongs to the technical field of engine testing equipment, and relates to an engine bench oil inlet and outlet oil pressure regulating device. Background technique [0002] In the existing technology, the oil inlet and outlet pressures are not precisely controlled during the engine test. With the improvement of test standards, the performance and emission indicators are more stringent, and the impact of inaccurate control of the oil inlet and outlet pressures is no longer satisfactory Test method requirements. In addition, with the upgrading of fuel supply pump products, the new fuel pump also has very high control requirements for the inlet and return oil pressure. If the pressure is too high, the fuel pump product will be damaged (the camshaft seal ring of the diesel lubricated fuel pump is broken). Contents of the invention [0003] The purpose of the present invention is to provide an engine bench oil inlet and outlet oil pressure...
