Abstract: An improved apparatus for injecting and igniting fuel in an internal combustion engine includes a nozzle with a bore and a tip at a distal end. The bore includes a longitudinal axis and an annular valve seat. A needle reciprocates within the bore and in combination with the annular valve seat forms an injection valve where in a closed position the needle abuts the annular valve seat and in an open position the needle is spaced apart from the annular valve seat. A retainer axially protrudes from the tip of the nozzle along the longitudinal axis thereof whereby an annular mixing space extends between the retainer and the tip of the nozzle. There is an igniter secured to the nozzle that includes a positive-ignition source forming an ignition zone within a portion of the annular mixing space. Nozzle arrangements include those with both pilot hole and main holes in the nozzle extending between the plenum and outside the nozzle where the main hole longitudinal axis bypasses the retainer and a pilot fuel jet from the pilot hole(s) is retained and redirected such that an ignitable fuel-air mixture is formed within the annular mixing space. Nozzle arrangements also include nozzles with a plurality of main holes and no separate pilot holes in which the main longitudinal axis bypasses the retainer such that a main fuel jet is scraped by the retainer and scraped fuel is retained and redirected such that an ignitable fuel-air mixture is formed within the annular mixing space. The igniter is actuated to ignite the ignitable fuel-air mixtures.

Abstract: An auxiliary chamber (51) having a spark plug (54) and an auxiliary fuel injector is formed at the central part of the top surface of the main combustion chamber (2). When making an air-fuel mixture in the auxiliary chamber (51) burn by the spark plug (54), an air-fuel mixture in the main combustion chamber (2) is made to burn by jet flames ejected from the communicating holes (52). The injection ports of the auxiliary fuel injector (53) are oriented toward a tumble flow inflow peripheral region (R) which is located on the peripheral part of the end portion of the auxiliary chamber (51) at a place located on a side where the tumble flow W flows in from the communicating holes (52). When the tumble flow (W) is made to be generated in the main combustion chamber (2) by the tumble flow control valve (48), auxiliary fuel (QF) is injected from the auxiliary fuel injector (53) toward the tumble flow inflow peripheral region (R) of the auxiliary chamber (51).

The spark plug has a supply passage, a center conductor, an insulator surrounding the center conductor, and a metallic body surrounding the insulator. A center electrode and at least one ground electrode form a spark air gap. In the region of its front end, the spark plug has an external thread for screwing the spark plug into a component of the internal combustion engine and has at least one discharge opening of the supply passage. The spark plug, at its front end, has, attached to the body, a sleeve that contains the external thread; the body has, on its outside, at least one groove that forms a section of the supply passage; and the sleeve has a heat conducting section that contains at least a part of the external thread and that is in contact with the body and covers at least portions of the groove.

Abstract: An internal combustion engine has fuel injectors for a first fuel and separate fuel injector-igniters for a second fuel. The first fuel may be a compression-ignition fuel such as diesel fuel while the second fuel is a lower cetane fuel that requires external energy for controlled ignition. For example, the second fuel may be natural gas. Such engines have applications in a wide range of fields, particularly those fields requiring large-displacement slow- and medium-speed engines. Such engines are particularly well adapted for use in railway locomotives. A locomotive equipped with such an engine may operate primarily on natural gas, and thereby take advantage of the significant price difference between natural gas and diesel fuel, while permitting switch over to operation on 100% diesel fuel.

Abstract: Methods, systems, and devices are disclosed for injecting a fuel using Lorentz forces. In one aspect, a method to inject a fuel includes distributing a fuel between electrodes configured at a port of a chamber, generating an ion current of ionized fuel particles by applying an electric field between the electrodes to ionize at least some of the fuel, and producing a Lorentz force to accelerate the ionized fuel particles into the chamber. In some implementations of the method, the accelerated ionized fuel particles into the chamber initiate a combustion process with oxidant compounds present in the chamber. In some implementations, the method further comprises applying an electric potential on an antenna electrode interfaced at the port to induce a corona discharge into the chamber, in which the corona discharge ignites the ionized fuel particles within the chamber.
