Abstract: A basic regeneration completion pressure difference value is set based on a predicted deposition amount of incombustible deposits produced steadily on a particulate filter, and a corrected regeneration completion pressure difference value higher than the basic regeneration completion pressure difference value is set based on a deposition amount of incombustible deposits deposited unsteadily on the particulate filter. After regeneration processing starts, when a time for which a pressure difference value is maintained to be equal to or greater than the basic regeneration completion pressure difference value after decreasing to the corrected regeneration completion pressure difference value exceeds a prescribed regeneration completion time, the regeneration processing ends.

Abstract: A control apparatus includes a control member performing a center position control to align a specific crank angle of an engine with EGR system, which angle is called as center position, with a reference position when the engine is driven under a predetermined range. The center position is a geometric center of a figure defined by a transition of heat generation ratio through fuel combustion. The control member runs an ignition acceleration procedure when the engine satisfies at least one of specific conditions during an exhaust gas recirculation under the center position control. The ignition acceleration procedure is to inject more fuel for a pilot injection than a base amount determined in accordance with the center position control. The specific conditions includes: a condition that an engine load is smaller than a threshold value; and a condition that an engine rotational speed is smaller than a threshold value.

Abstract: The present invention relates to an internal combustion engine. An object of the invention is to allow an effect produced by are anodic oxide film to be exerted while suppressing a decrease in the combustion rate. A piston 10 includes a cavity portion 20 and a tapered portion 26 that is formed so as to surround the cavity portion 20 on an outer side thereof. The diameter of the tapered portion 26 decreases progressively in the downward direction from the top face side of the piston. A squish portion 28 is formed on an outer side of the tapered portion 26. An anodic oxide film 30 is formed on a surface (tapered face) of the tapered portion 26 and a surface (squish face) of the squish portion 28. The anodic oxide film 30 is not formed on the surface (cavity face) of the cavity portion 20.

Abstract: The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet.
