摘要： A fuel gas feed and ignition apparatus for a gas engine (1) with a combustion chamber includes a number of injection channels (37), a main fuel gas feed line (24) for main fuel gas in which a main fuel gas valve (21) is arranged, and a number of torch channels (52) for hot combustion gas connected to a pre-combustion chamber (15), wherein an ignition fuel supply line (17) leads to the pre-combustion chamber (15) and a pre-combustion chamber valve (18) is arranged in the ignition fuel supply line (17). Control of both the time and the duration and thus also the quantity of the injection of main fuel gas, as well as of ignition fuel for the pre-combustion chamber completely independently of one another and in a precise and, above all, rapid manner is achieved in that both the main fuel gas valve (21) and the pre-combustion chamber valve (18) are embodied as an electrically-actuated, electronically-controlled valve.

摘要： A fuel injector (1) is provided which comprises a valve member (11), a valve member guide (12) and a spring chamber (40). Discharge of fuel out of a fuel injector outlet (21) is controlled by movement of the valve member (11) within a bore (23) of the valve member guide (12). The spring chamber (40) contains a biasing member (50), for example a compression spring, which biases the valve member (11) into contact with a valve seat (20) when in a closed configuration.A fuel supply passage (80) is provided, which by-passes the spring chamber (40), to direct a flow of the fuel to an outlet chamber (22) of the fuel injector (1) and a cleaning fluid supply passage (90) is provided to supply a pressurised cleaning fluid to a second end (25) of the bore (23) to restrict leakage of the fuel from the outlet chamber (22) towards the second end (25) of the bore (23) along a clearance (29) extending between the valve member (11) and the valve member guide (12).

摘要： An apparatus and process for production of a liquid containing fuel that avoid the need to add any extra surfactant and also the need to apply ultrasonic wave energy and attain high stability of minute bubbles, etc. Production apparatus for a liquid containing fuel comprises pump for pressurizing a stored fuel and nanobubble generating unit adapted to inject a liquid containing the pressurized fuel. The apparatus may be equipped with homogenizing means for storing the liquid containing fuel. The process for production of a liquid containing fuel is characterized by sequentially performing storing of a liquid containing fuel in storage means, pressurizing the liquid so as to obtain a high-pressure liquid with a given pressure, injecting the same through a nozzle into a matrix of liquid containing fuel and effecting collision thereof with a wall so that nanobubbles of foreign substance are dispersed in the matrix of liquid containing fuel.

摘要： A metering valve having a valve housing, a channel, a valve body that can be moved in order to open and close the metering valve, and a spring, which applies a spring force to the valve body and thus keeps the valve body in a rest position. The spring is supported on at least one calibration body. The valve body, the spring, and the at least one calibration body are arranged in the channel, and the at least one calibration body is supported by a supporting component fastened in the valve housing by a material-bonding connection. A segment of the supporting component protrudes from the valve housing.

摘要： Injection nozzle for liquid media, with a nozzle body with an inlet duct and swirl ducts connected thereto and tangentially directed into a turbulence space, as well as with a return duct, whereby the turbulence space is substantially formed by an annular groove in the face side of the nozzle on the outlet side. There is a cover plate fastened thereon and provided with a central outlet opening, and the cover plate forms with the nozzle core a disk-shaped narrow gap. Thus, the nozzle body has in its face surface on the outlet side a central depression for receiving and locking into place the cover plate, whose diameter is smaller than the diameter of the nozzle body. The depth of the depression is smaller than the thickness of the cover plate, and the cover plate is seated on a collar of the nozzle casing enclosing the nozzle body.
