Automotive device which reduces and stabilizes the natural gas pressure, in order to properly feed the engine. The three reduction stages provide stability at both high and low pressures. The pressure regulator is equipped with a pressure relief valve and a low pressure solenoid valve fitted upstream of the third stage. The necessary operating heat is provided by a connection with the engine coolant system. The engine idling gas flow is activated through the gas pipe main flow as a result of the negative pressure generated by the engine.
CN04 is equipped with an electronic starting device with a built-in safety system which closes the gas solenoid valve when the engine stops.
