A control device meant to reduce LPG pressure and to vaporize it for a regular flow of gas to the engine. Its electronic starting device and mechanical safety system control and regulate the supply of gas to the engine. Its solenoid valve controls the inlet by not allowing the LPG to enter the vaporizer when the engine does not need it. A slow idling adjustment for fine tuning works as a check for the vaporizer helping the vehicle with an instant and efficient start of the engine.
