Device for vaporizing fuel and controlling the temperature of the fuel in an internal combustion engine

摘要

A device for vaporizing fuel in an internal combustion engine whereby the fuel-air ratio in the mixture zone is varied by controlling the temperature of the vaporized fuel without the need for changing the orifice cross section of the nozzle. The fuel is first heated by means of a first electric heater and by the hot engine exhaust gases flowing through a pipe in the heat exchanger. Additional heat may be applied to the fuel by means of the cooling oil returning from the nozzle and electrode carrier which injects the fuel into the combustion zone.
