摘要： A four-stroke piston engine in which air is drawn into a cylinder while rotary motion about the cylinder axis is imparted to the air. Fuel may be blown/injected into the air during its rotation in the cylinder while the fuel supply is located on the axis of the cylinder and supplies at least one jet of fuel initially directed radially outwardly and which jet of fuel in cooperation with the rotating air forms at least one helical stream of mixture within the cylinder, preferably during the compression stroke, which is transformed into a coherent mixture zone enclosed by a ring of air upon completion of compression. The piston may have a recess so that when the piston approaches top dead center an enriched zone is formed in the lower region of the compression space which can be ignited by electrodes disposed in said lower region of the compression space. The stratified charge in the cylinder of the stratified-charge engine comprises a mixture zone of comparatively small volume and a mixture zone of comparatively large volume which may have different fuel concentrations plus a thermally insulating zone of air.

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.

摘要： The method and device for the formation of a fuel-air mixture upstream of the mixture-forming nozzles of an internal combustion engine. The combustible fuel is vaporized and introduced into a combustion chamber through a fuel vapor passage and nozzles, and an air pump connected to the fuel vapor passage introduces pressurized air therein at a selected time in the engine cycle. This results in the discharge of pressurized air together with vaporized fuel through the nozzle into the combustion chamber to form a zone of fuel-air mixture enveloped by a jacket of air during the compression stroke of the engine and protect the nozzles and fuel passages against the hot combustion gases. Air without fuel is then discharged into the combustion chamber during combustion of the vaporized fuel. An auxiliary air chamber connected to the main chamber of the air pump through a valve that is opened and closed at selected times during the cycle of the engine serves to increase the mass of gas delivered by the pump.
