In a gas-cylinder installation, when the engine is running in gas-diesel mode, the gas pressure decreases from 20 MPa to atmospheric, which is accompanied by its cooling
The high pressure reducer is designed to reduce the pressure of compressed gas to 0.95 ... 1.1 MPa by one-stage expansion; has a safety valve 12 (fig.1),
The solenoid valve is used to pass gas to the low pressure reducer when the engine is switched to gas-diesel mode
