摘要:
A dual fluid injection system which comprises a liquid fuel metering device, a fluid delivery device, and apparatus providing an interface therebetween. The interface conveys liquid fuel along a flow path from the metering device to a mixing zone for mixing with air from a pressurized supply to provide an air-fuel mixture for injection by the fluid delivery device into a combustion chamber of an internal combustion engine. The flow path may involve a directional change by way of a turn section. The flow path is sized such that liquid fuel is retained therein by virtue of capillary action, whereby a quantity of liquid fuel is retained after a delivery event such that the flow path remains substantially filled with liquid fuel in readiness for the next delivery event during operation of the engine.

A fuel injector includes a nozzle body, and spray ducts coupled to the nozzle body and in spray path alignment with spray orifices therein. A nozzle check is movable within the nozzle body to open and close the spray orifices. Each of the spray ducts defines a duct center axis, and includes a center body forming, together with a duct inner surface, a spray jet passage circumferential of the duct center axis and reduced in area in a direction of spray jet advancement from the nozzle body.

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.

This invention refers to a process for achieving the total combustion of fuels, which can reduce pollution in the atmosphere, solve (in great part) the climate crisis, stop the greenhouse effect-humanity is facing, and combat global warming. The invention's field of use is very wide, for example in engines of vehicles, in engines for airplane propulsion, in engines for ships, and in other equipment for transportation, combustion, and generation of electricity. This process involves using several types of injectors and compressed air. In this regard, the air can be compressed at a pressure of 5 to ∞ ATM, be passed through a vacuum created in a pipe, and absorb fuel in the mass of the compressed air to achieve total combustion and the number of compressed air molecules necessary to cause the total combustion of one molecule of hydrocarbon, for the various types of hydrocarbons discussed herein.

The disclosure provides a fuel injection nozzle. The fuel injection nozzle includes a nozzle body, with the nozzle body defining a central bore. A fuel atomizer is disposed in the central bore. The fuel atomizer defines a spill-return bore and a swirl chamber. The swirl chamber is in fluid communication with the central bore. The spill-return bore includes a return swirler approximate the swirl chamber. An air supply pump is coupled to the fuel atomizer and is in fluid communication with the spill-return bore. The air supply pump is configured to selectively inject air into the swirl chamber through the spill-return bore.

A V-type internal combustion engine includes cylinder heads having respective compressed-air supply channels extending therein for providing fluid communication between an air compressor and charge injectors. Formation of condensation in the compressed-air supply channels is prevented. Charge injectors are provided in the respective cylinder heads, for directly injecting charges of fuel-air mixture into combustion chambers in cylinders. Compressed-air supply channels extend from an air compressor to the respective charge injectors, including a shared channel provided in a crankcase, and branched supply channels provided in each of the respective cylinder blocks. The compressed-air supply channels are internal conduits formed by attaching the cylinder blocks to the crankcase. In addition, cooling of the compressed air in the compressed-air supply channels is prevented during engine operation, so that formation of condensation within the compressed-air supply channels is prevented.
摘要:
A gasoline engine is provided which is capable of introducing a large amount of EGR gas for performing homogeneous combustion and thus offering a good fuel economy. An external EGR mechanism or an internal EGR mechanism is used to introduce an EGR gas into a combustion chamber (a cylinder). A mixture of fresh air and fuel is thereafter directly injected from a mixture injection valve into the combustion chamber, thereby forming a region of said mixture in an area near an ignition plug. In addition, engine operating parameters are controlled in accordance with the amount of fresh air supplied into the combustion chamber (cylinder) after an intake valve has been closed. This makes possible homogeneous combustion using a large amount of EGR, which eventually increases fuel economy.
