Abstract: 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.

Abstract: A liquid fuel injector for a fuel system in an internal combustion engine includes two injection control valves for controlling two outlet checks. A common nozzle supply cavity is fluidly connected to an inlet passage and supplies each of the two sets of nozzle outlets opened and closed by the outlet checks. A first nozzle outlet set forms a narrower spray angle and has a first combination of outlet number and outlet size, and a second nozzle outlet set forms a wider spray angle and has a second combination of outlet number and outlet size. The first nozzle outlet set has a greater steady flow than the second nozzle outlet set.

Abstract: A fuel system is disclosed for use with an engine, including a fuel injector assembly fluidly coupled with a low-pressure fuel conduit, an accumulator, and a cap within an opening in the accumulator. The fuel injector assembly may be structured to draw in low-pressure fuel, pressurize the fuel, and store the pressurized fuel in the accumulator for injection to a combustion chamber. The cap has a pressure sensor and a pressure relief valve therein, and drains fuel leaked past fluid seals between the cap and each of the pressure sensor, the pressure relief valve, and the accumulator by way of a common drain line.

Abstract: An assembly at least comprising a fuel injector for dual fuel operation of an internal combustion engine. The assembly includes a nozzle holder defining a fuel circuit and provided with a nose adapted in use to be in connection with a combustion space of an internal combustion engine, and first and second nozzles in communication with the fuel circuit in the nozzle holder for directly injecting liquid fuel into the combustion space of the internal combustion engine for ignition of a combustible mixture present in the combustion space. The first and second nozzles adjacent to the nose of the nozzle holder are interconnected by a cooling channel. At each actuation of a fuel pump upstream of the first and second nozzles, substantially a full volume of fuel pumped during actuation of the fuel pump is allowed to flow through the cooling channel and via the first and second nozzles.
