<p>The invention relates to liquefied gas feed systems for internal combustion engines. The liquefied gas feed system for an internal combustion engine comprises a gas cylinder, an electromagnetic gas shut-off valve, a vaporizer/regulator, an electronic control unit, an electric commutator, a switch unit, liquefied phase and vapor phase electromagnetic gas valves, a pressure control device, and a gas safety valve. The gas cylinder contains a shut-off and regulating unit with a multivalve, and liquefied phase and vapor phase valves. The liquefied phase and vapor phase electromagnetic valves supply gas to the vaporizer/regulator. The vaporizer/regulator is connected by pipes to the electromagnetic gas shut-off valve and by the pressure control device to the inlet header of the internal combustion engine. The vaporizer/regulator is connected by electric wires to heat-sensitive elements of the electric commutator, provided with the switch unit. The electronic control unit is connected by electric wires to the liquefied gas phase and to the electromagnetic gas shut-off valve as well as to gas nozzles and to a 'gas/gasoline' switch. The technical result is that the internal combustion engine can be cold started using the liquefied gas in the vapor phase and that, when stopped, the liquefied gas supply system is set for subsequent start-up.</p> |
