摘要： A combustion chamber includes an upstream end wall having an aperture and a fuel injector. An air swirler is mounted such that the air swirler is movable radially with respect to the aperture. An inner wall of the air swirler has a first portion. A fuel injector head of the fuel injector is arranged coaxially within the air swirler. An outer wall of the fuel injector head has a first portion. The inner diameter of the first portion of the air swirler is less than the outer diameter of the first portion of the fuel injector head. One of the first portions is elastically radially deformable to allow the fuel injector head to be installed and removed from the air swirler. The inner wall and the outer wall have inter-engaging radially and axially extending faces to align the fuel injector head axially and radially within the air swirler.

摘要： There is provided an airflow control device of an internal combustion engine comprising: a plasma actuator provided in an intake passage, a fuel injector for port injection provided in the intake passage so as to inject fuel toward the plasma actuator and a control unit for controlling them. The control unit is configured to actuate the plasma actuator after valve opening of an intake valve, in addition to causing the fuel injector to perform an operation of fuel injection, and causing the plasma actuator to perform an operation in a part of a valve closing period of the intake valve. Furthermore, the control unit includes a determination unit to determine whether or not water has adhered to the plasma actuator, and makes port injection operation and plasma actuator operation be performed only when water has adhered.

摘要： A fuel injector for internal combustion engines is provided, which has a valve seat member, bordering a valve chamber, having a valve seat and spray orifices and a central blind-end bore as well as a valve member that is able to be driven to cause a lift motion having a closing head, which, together with a valve seat, forms a sealing seat lying upstream of the spray orifices. In order to prevent an underpressure developing in the blind-end bore in the closing phase of the sealing seat, and a partial return flow of the fuel connected with it, the closing head of the valve member is provided, at its end face facing towards the valve seat member, with a plunger sticking out from closing head, which has a shape adjusted to the contour of the blind-end bore, and dips into the blind-end bore when the sealing seat is closed.

摘要： A method and system delivers a cryogenically stored fuel in a gaseous state into the air intake system of a gaseous fuelled internal combustion engine. The method involves measuring the pressure in the vapor space of the cryogenic storage vessel, comparing the measured pressure to a required fuel supply pressure and supplying fuel in gaseous state directly from the vapor space of the cryogenic storage vessel to the fuel delivery line that supplies fuel to the engine, when the pressure measured in the vapor space of the cryogenic storage vessel is equal to or higher than the required fuel supply pressure. The method further involves activating a cryogenic pump to deliver fuel to the internal combustion engine from the liquid space of the cryogenic storage vessel when the measured pressure in the vapor space is lower than the required fuel supply pressure.

摘要： The present invention relates to fuel atomizers and fuel injectors capable of being configured to atomize fuel for internal combustion engines. A fuel atomizer for engagement to a fuel injector comprises a nozzle and one or more stacked wafers disposed within the nozzle. The nozzle has an input aperture adapted to engage an outlet of a fuel injector, an output aperture for discharging fuel injected by the fuel injector, and an air supply aperture for receiving air into the nozzle. The wafers are adapted to enable received air to impart energy on the fuel injected from the fuel injector and to enable the fuel to be discharged from the output aperture. A fuel injector capable of being configured to atomize fuel is also provided, in which a fuel injector body is configured to output a fuel spray and the fuel atomizer nozzle discharges the fuel spray.

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.
