High speed internal combustion engine simulation pressurization system testing device

Abstract

The invention relates to the internal combustion engine testing technology field, and provides a high speed internal combustion engine simulation pressurization system testing device. The high speed internal combustion engine simulation pressurization system testing device comprises a heating box, the air inlet of which is communicated with an air compressor by a pressure regulation valve I. The heating box has two air outlet pipes, and one is connected with a steady head tank, and the other is provided with a pressure relief valve. The air outlet of the steady head tank is connected with a cylinder. The output end of the cylinder is connected with a pressure regulation tank, and a water cooling sleeve is disposed on the pressure regulation in a sleeved way. The water inlet of the water cooling sleeve is disposed on the near outlet end of the pressure regulation tank, and the water outlet of the water cooling sleeve is disposed on the near inlet end of the pressure regulation tank. The outlet end of the pressure regulation tank is connected with an outlet pipeline. The air transmission pipeline is provided with a back pressure valve, and a pipeline between the back pressure valve and the pressure regulation tank is also provided with a pressure regulation valve II. The high speed internal combustion engine simulation pressurization system testing device is advantageous in that fluctuation of an air flow is effectively reduced, and the temperature of the high temperature air exhausted from the cylinder is effectively reduced, and the pressure regulation valves are protected from being burned out.

Description

technical field [0001] The technical field of internal combustion engine test of the present invention mainly relates to a high-speed internal combustion engine simulated booster system test device. Background technique [0002] The internal combustion engine is a heat engine that mixes liquid or gaseous fuel with air and directly inputs it into the high-pressure combustion chamber inside the cylinder for combustion and explosion to generate power. The internal combustion engine completes the four processes of intake, compression, work and exhaust every time it performs work. In the test device for the simulated booster system of the internal combustion engine, after the compressed air is heated by the heating box, the temperature rises, the air flow fluctuates when entering the cylinder, and the air pressure is unstable; after the work is completed, the gas discharged from the cylinder enters the pressure regulating tank, and then passes The pressure regulating valve and th...
