Abstract: The invention relates to a valve arrangement (2) for metering a fluid medium into an exhaust line (22), comprising a valve seat (10) which acts together with a closing body (12) and in which a valve passage (14) is implemented, and a perforated disc (6) that is disposed downstream of the valve seat, closes off the valve passage, and has at least one axial hole (8) in the area of the valve passage through which the fluid medium can be injected into the exhaust line (22). The valve arrangement further comprises a connecting flange (16) for connecting the valve arrangement (2) to the exhaust line (22) in a fluid-tight manner, wherein the perforated disc (6) extends from the valve passage to the connecting flange and is implemented such that said perforated disc seals the connecting flange against the exhaust line in a fluid-tight manner in the installed state. A separate seal is thus no longer required, because the perforated disc performs the sealing function.

Abstract: A conventional gasoline engine is retrofitted and calibrated to operate as a bi-fuel engine using Hydrogen as the second fuel. When operated with Hydrogen, which typically leads to a reduction of engine output power, the engine is preferably operated in a charged mode and in a lean mode with the engine throttle kept in a wide open position during charged and lean mode operation resulting in a more efficient engine with a reduction of engine output power loss.

Abstract: A method and apparatus are disclosed for inducing a supercavitating flow inside a fuel injection nozzle orifice to reduce the penetration length of the fuel spray, maintain high levels of fuel atomization, and improve uniformity of the fuel spray exiting the nozzle such that high-pressure injectors can be used on small engines. This reduction in penetration length is accomplished without any reduction in upstream fuel pressure.

Abstract: A fuel injection valve of an internal combustion engine includes a measuring plate that has at least one injection hole. Fuel that has flowed along an inner wall surface of the measuring plate flows into the injection hole through an injection hole entrance that is formed in the inner wall surface of the measuring plate, passes through the injection hole, and is injected through an injection hole exit that is formed in an outer wall surface of the measuring plate. A recess is formed from an injection hole entrance rim to an injection hole exit rim in an upstream section of the inner wall surface of the injection hole in a fuel flow direction along the inner wall surface of the measuring plate.
