8results about "Low pressure fuel injection" patented technology

The application relates to the field of aeroengines, in particular to a two-stroke aero-piston engine air intake system and an air intake flow control method. The system comprises an air filter, a throttle body, an oil injector, a reed valve and a fuel supply unit for supplying oil to the oil injector which are communicated through a connecting pipeline, and further comprises a cooling control subsystem, the cooling control subsystem comprising a cooling injector which is arranged on the connecting pipeline downstream of the throttle body and upstream of the oil injector; the inner wall surface of the connecting pipeline is provided with a non-uniform protruding structure to improve the proportion of the air intake along the resistance. The scheme can solve the technical problem that the air intake flow of the two-stroke aero-piston engine has large discreteness under low load, and realizes the technical effect of improving the consistency of the air intake flow under the low load of the engine.

This technology provides a way to heat a pressure regulator with a simple configuration. [Solution] The ammonia supply system comprises a vaporizer for vaporizing liquid ammonia and a pressure regulator for adjusting the pressure of the gaseous ammonia after vaporization by the vaporizer. The vaporizer has a spiral ammonia flow path through which liquid ammonia and gaseous ammonia flow. The pressure regulator is located inside the spiral ammonia flow path.

A throttle body (100) for a vehicle is disclosed. The throttle body (100) comprises a housing (102) defined with a primary air passage (104) and a secondary air passage (130) fluidically coupled to the primary air passage (104). The throttle body (100) comprises a throttle plate (108) disposed in the primary air passage (104). The throttle plate (108) is configured to regulate an airflow through the primary air passage (104) under a normal condition. The throttle body (100) comprises a solenoid valve (132) disposed in the secondary air passage (130). The solenoid valve (132) is configured to selectively allow the air to flow through the secondary air passage (130). The throttle body (100) comprises a control unit coupled to the solenoid valve (132). The control unit is configured to selectively open the solenoid valve (132) at a vehicle fault condition.

A device may include a surface configured to be disposed adjacent the hollow cylinder of the engine head. The device may further include a fuel injector disposed adjacent the surface, the fuel injector including an outlet configured to be disposed adjacent a cylinder periphery of the hollow cylinder of the engine.

The internal combustion engine injector mounting device (1700) is configured to i) secure an injector (36) to an internal combustion engine body (14) so ​​that the injector can inject heated aqueous fluid and fuel into a combustion chamber (12) of the internal combustion engine, and ii) hold a catalyst (1714) so ​​that the heated aqueous fluid and fuel pass through the catalyst as they are injected into the combustion chamber. The catalyst is contained within the mounting body to protect it from oxidation due to the combustion process that occurs in the combustion chamber during use.

The present disclosure provides "fuel injectors". A fuel injector and method are disclosed, the fuel injector comprising an injector body with a fuel capsule and an end of the injector body positioned in a combustion chamber. A main fuel passage having a varying cross-sectional area forming a pressure reduction zone fluidically couples the fuel capsule to the combustion chamber. One or more additional passages fluidically couple the pressure reduction zone with one or both of the fuel capsule and the combustion chamber.

Presented is a method, system and apparatus for fuel flow control. An exemplary fuel flow control apparatus includes a fuel inlet operable to receive a flow, and a fuel shut-off valve fluidly connected to receive the flow from the fuel inlet, the fuel shut-off valve is operable to allow the flow in a first configuration and prevent the flow in a second configuration. The apparatus further includes a pressure regulator fluidly connected to receive the flow from the fuel shut-off valve, a flow control valve fluidly connected to receive the flow from the pressure regulator, the flow control valve comprising a position sensor operable to sense a position of the flow control valve, an injector fluidly connected in parallel to the flow control valve to receive the flow from the pressure regulator, and a fuel outlet.
