    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： 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 system, including a primary fuel tank that stores a fuel, a fuel reformer that reforms the fuel from the primary fuel tank, a secondary fuel tank that stores the fuel reformed by the fuel reformer, a fuel injection device that injects the fuel that is selectably supplied from either the primary fuel tank or secondary fuel tank into a combustion chamber, a sensor that detects the quantity of fuel remaining in the secondary fuel tank, and a control device that sets and outputs a load and revolution speed of the engine. The control device is configured to set the engine load and engine revolution speed according to a request output determined based upon an operation performed by an operator. The engine load and engine revolution speed when the quantity of fuel remaining in the secondary fuel tank is more than a predetermined value, are set different than when the quantity of fuel remaining in the secondary fuel tank is less than the predetermined value.

    摘要： An direct fuel injection spark ignition internal combustion engine comprises a fuel injection valve arranged at a substantially center part of an upper are of a combustion chamber, and a piston having a crown surface with a cavity shaped so that a center axis of a substantially conical-shaped fuel stream injected from the fuel injection valve is substantially coincident with a center axis of the piston. In a low-load stratified combustion operating region when spark ignition is executed, the fuel injection angle is increased to form a first combustible air-fuel mixture before the fuel stream collides against the cavity of the piston crown surface. In a high-load stratified combustion operating region, the fuel injection angle is reduced to form a second combustible air-fuel mixture after the fuel stream collides against the cavity of the piston crown surface.
