Pneumatic-fuel hybrid test system

The utility model relates to a dynamic test system, and aims to provide a pneumatic-fuel hybrid test system. In the test system, an eddy current dynamometer is connected with an air-powered engine; awater power dynamometer is connected with an internal combustion engine; a high pressure gas storage tank is further comprised, and is connected with a heat exchanger, a stable pressure box and the air-powered engine in sequence through pipelines; a high temperature exhaust pipeline of the internal combustion engine is connected with the heat exchanger, and is opened to atmosphere after carrying out heat exchange with the high pressure gas; a pressure sensor is arranged on the stable pressure box; an air flow meter is arranged on the pipeline at the outlet of the gas tank; a thermocouple is arranged on each high pressure gas pipeline on two sides of the heat exchanger; and the pressure sensor, the air flow meter and the thermocouples are all connected with a computer. The utility model provides the practicable test system for proving the correctness of the pneumatic-fuel hybrid theory, and provides reliable experiment parameters for realizing a more advanced pneumatic-fuel hybrid system in future.
