摘要： A dual-fluid injection system for an internal combustion engine, and an unmanned aerial vehicle (UAV) powered by an engine having the dual-fluid injection system. The dual-fluid injection system comprises a liquid fuel metering device and a fluid delivery device operating in tandem. A gas supply system comprising an air compressor and an air delivery path extending between the air compressor and the fluid delivery device is provided to supply pressurised air to the fluid delivery device. The gas supply system comprises an air compressor and an air delivery path extending between the air compressor and the fluid delivery device. A fuel supply system is adapted to deliver liquid fuel to the liquid fuel metering device. A fuel-air regulator is provided for regulating fuel pressure with reference to air pressure to establish and maintain a requisite pressure differential between the fuel pressure and the air pressure. The fuel-air regulator is located remotely from the fluid delivery device and more particularly in close proximity to the air compressor. In a preferred arrangement, the fuel-air regulator is mounted on or integrated with the air compressor or a part thereof.

摘要： A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

摘要： A liquid injector atomizer for direct injection in to the cylinder of an internal combustion engine is provided, with a supply of pressurized liquid a supply of pressurized gas, a body, and a nozzle with two or more orifices each for the liquid and the gas. Each orifice directs a jet of metered pressurized liquid or gas out of the injector body. At least two of the liquid jets are aimed at one or more collision points, where at least two gas jet streams collide at a same collision point or another collision point, thereby creating a finely atomized liquid.

摘要： In order to supply an air-fuel mixture composed of the fuel and compressed air to a combustion chamber of an engine, an air-fuel mixture valve is opened by a valve body which is moved via the core shifted by magnetic force of the electromagnetic coil. The invention provides a method of determining the magnetic force of the electromagnetic coil on the basis of the relationship defined by Fm.gtoreq.Fv-fa, where Fm denotes axial tension depending upon the magnetic force of the electromagnetic coil, Fv denotes force necessary for opening or closing the empty air-fuel mixture valve, and fa denotes force for compressed air to open the air-fuel mixture valve. The pressure of the compressed air is used as the auxiliary force to open the air-fuel mixture valve. This allows the air-fuel mixture valve to be made more compact and reduces power consumption of the electromagnetic coil.

摘要： A water-cooled, two-stroke crankcase compression internal combustion engine for powering a motor vehicle. The engine includes a piston, piston rings, and cylinder bore arrangement that are constructed to inhibit piston ring sticking by cooling the piston ring gaps by holding them against rotation and spraying fuel from a fuel injector toward the gap for cooling it. In addition, overheating of the small end of the connecting rod is inhibited by surface treating portions of the piston to render them harder and less heat conductive. Scuffing of the piston, piston rings, and cylinder bore are reduced by surface treating the area of the head of the piston around the ring grooves so as to trap and retain lubricant.
