Abstract: A control apparatus is provided, which controls combustion state such that the Heat Release Rate Barycentric Position (Gc) coincides with the Target Barycentric Position (Gc*), and which can prevent an increase in the combustion noise caused by an increase in an ignition lag which occurs in a case where an EGR apparatus is in execution, and, a rotational speed is low or an engine load is low. The control apparatus (ECU70) prevents the increase in the ignition lag by increasing a supercharging pressure of a supercharger (44) which the engine (10) is equipped with, thus, it prevents the increase in the combustion noise.

Abstract: The invention relates to a control apparatus of an engine. The apparatus carries out a minute-injection for injecting a minute amount of a fuel so as not to generate an engine torque when a required engine load is zero. The apparatus calculates at least one coefficient for correcting a heat release gravity position calculated when the minute-injection is carried out such that it corresponds to its base position and/or for correcting a heat release rate corresponding the gravity position calculated when the minute-injection is carried out such that it corresponds to its base rate. When the required engine load is larger than zero, the apparatus controls the gravity position corrected by the coefficient to its target position.

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: 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: A control device for an internal combustion engine is provided that is configured to suppress a decrease in volumetric efficiency due to an influence of a pulsation of an intake air pressure that a turbo-supercharger generates. In a case where the internal combustion engine is in a specific operating state where a local minimum point of the pulsation of the intake air pressure exists within an opening period of an intake valve, the control device actuates a second supercharger that is driven by a motive power other than exhaust gas and is disposed downstream relative to the turbo-supercharger, and also opens a bypass valve provided in a bypass passage that bypasses the second supercharger.
