摘要： The present disclosure is intended to provide an internal combustion engine that can inhibit fuel from adhering to a piston and can reduce generation of soot. An internal combustion engine includes a piston, a cylinder accommodating the piston, and an injector including a nozzle that has a plurality of nozzle holes configured to inject fuel into the cylinder from above the cylinder. Among the plurality of nozzle holes, a sixth nozzle hole an axial direction of which is the most deflected toward the piston has a nozzle hole diameter larger than nozzle hole diameters of the other nozzle holes, and the nozzle hole diameter of the sixth nozzle hole corresponds to at least 20% of the total of the nozzle hole diameters of the other nozzle holes.

摘要： In at least some implementations, a fuel metering valve, includes a bobbin defining a passage and having one or more voids in the surface of the bobbin that defines the passage, aa wire coil around the bobbin and an armature. The armature is received within the passage in the bobbin and movable relative to the bobbin from a first position to a second position when electricity is supplied to the wire coil.

摘要： A fuel rail assembly for delivering fuel to at least one fuel injector. The assembly includes a main pipe defining a passageway through which fuel passes to the fuel injector. A fastener mount is forged with the main pipe such that the fastener mount is integral with the main pipe. The fastener mount defines a first aperture configured to receive a fastener for mounting the main pipe. A wire harness mount is forged with the main pipe such that the wire harness mount is integral with the main pipe. The wire harness mount defines a second aperture configured to cooperate with a coupling member of a wire harness. The fastener mount and the wire harness mount are on a common side of the main pipe.

摘要： An engine including a main fuel injection valve, a pilot fuel injection valve, a liquid fuel supply rail pipe, and a pilot fuel supply rail pipe. The main fuel injection valve supplies liquid fuel from the liquid fuel supply rail pipe to a combustion chamber during combustion in a diffusion combustion system. The pilot fuel injection valve supplies pilot fuel from the pilot fuel supply rail pipe to the combustion chamber in order to ignite gaseous fuel during combustion in a premixed combustion system. The liquid fuel supply rail pipe is disposed at one side of an imaginary vertical plane (P1) including an axis of a crank shaft. The pilot fuel supply rail pipe is disposed at the side of the imaginary vertical plane at which the liquid fuel supply rail pipe is disposed.

摘要： An internal combustion engine, in particular a diesel engine, in particular of a motor vehicle, includes at least one working cylinder and one cylinder head closing the working cylinder, in which an injector for injecting fuel is situated for the working cylinder. The engine includes a clamping claw for the injector for injecting fuel, whose one end is supported on the other end, in which at least two arms are provided in such a way that one arm of the clamping claw acts upon an injector in each case, and the injector presses against a seat or a seal in the cylinder head in a sealing manner with the aid of a defined force. The engine also include a clamping screw designed as a push-through screw and including a screw head collar and a corresponding thread is provided in the cylinder head, which fastens the clamping claw at the cylinder head. The arms of the clamping claw are designed in such a way that the arms of the clamping claw are supported on a support surface at the injector and on a support surface at the cylinder head.

摘要： The invention relates to a fuel injection valve for the intermittent injection of fuel into the combustion chamber of an internal combustion engine having a housing which has a high pressure chamber and a low pressure chamber. In addition, the fuel injection valve has a control chamber which is divided by means of a control valve into a first and a second control chamber. The control valve in turn has a valve guide and a valve insert, wherein an outflow throttle which connects the first control chamber to the second control chamber is arranged in the valve guide. According to the invention, the connection which is formed by way of the outflow throttle between the first control chamber and the second control chamber can be interrupted temporarily in a targeted manner.

摘要： A hybrid engine having a plurality of combustion power assemblies disposed about an engine driveshaft on which is mounted spaced apart cams, each combustion power assembly disposed between the cams radially outward of the driveshaft and having a combustion cylinder with a fuel injector mounted thereon and with a reciprocating piston assembly disposed in each end of the combustion cylinder. A cam follower is attached to each piston assembly and engages a respective cam. An electric power assembly may be mounted radially outward from the driveshaft and adjacent at least one cam as a radial power assembly or may be mounted along the driveshaft between the two cams as an axial power assembly.
