摘要： An internal combustion engine is provided that basically comprises a cylinder block, a cylinder head, a piston, an auxiliary chamber partition wall and a spark plug. The auxiliary chamber partition wall is coupled to the cylinder head and extending toward the main chamber to form an auxiliary combustion chamber inside an area enclosed by the auxiliary chamber partition wall. The auxiliary chamber partition wall has at least one jet aperture through which the auxiliary combustion chamber fluidly communicates with the main combustion chamber. A tip portion of the auxiliary chamber partition wall that faces toward the piston has a smaller wall thickness than other portion of the auxiliary chamber partition wall.

摘要： An internal combustion engine includes neighboring main and auxiliary combustion chambers that are separated by a partition wall including a communicating passage. Ignition of an air/fuel mixture in the auxiliary combustion chamber produces a fuel torch that is jetted into an air/fuel mixture in the main combustion chamber. Under a predetermined operation condition, timing for opening an intake valve is retarded relative to both the timing for closing an exhaust valve and the timing for top dead center of a piston on an exhaust stroke. By retarding the timing for opening the intake valve, residual gas in the auxiliary combustion that is left over from a previous cycle can be reduced.

摘要： A direct fuel injection engine basically comprises a combustion chamber, a piston with a cavity, a fuel injection valve, a spark plug and a control unit. The fuel injection valve is configured and arranged to directly inject a fuel stream into the combustion chamber in a substantially constant hollow circular cone shape in a stratified combustion region. The control unit is configured to ignite a first air-fuel mixture formed directly after the fuel stream is injected and prior to a majority of the fuel stream striking the cavity when the direct fuel injection engine is operating in a low-load stratified combustion region, and to ignite a second air-fuel mixture formed after a majority of the fuel stream is guided by the cavity toward an upper portion of the combustion chamber above the cavity when the direct fuel injection engine is operating in a high-load stratified combustion region.
