摘要： 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).

摘要： 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.

摘要： 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.

The injector also includes an ignition conductor extending through the body from the first end portion to the second end portion, and an insulator extending longitudinally along the ignition conductor and surrounding at least a portion of the ignition conductor. The injector further includes a valve extending longitudinally along the insulator from the first end portion to the second end portion. The valve includes a sealing end portion, and the valve is movable along the insulator between an open position and a closed position. The injector also includes a valve seat at or proximate to the second end portion of the body. When the valve is in the open position the sealing end portion is spaced apart from the valve seat, and when the valve is in the closed position the sealing end portion contacts at least a portion of the valve seat.
