摘要： In a reciprocating piston engine employing a variable compression ratio mechanism configured to be linked to a reciprocating piston for variably adjusting a geometrical compression ratio by varying at least a top dead center position of the piston responsively to a controlled variable, a controller is configured to control the variable compression ratio mechanism depending on an engine operating condition. A part of a wall surface of a combustion chamber is formed of a non-metallic material having a higher heat-insulating and heat-reserving property as compared to a base structural material of each of the combustion chamber and the piston.

摘要： A link mechanism of an engine includes: an upper link having a first end connected to a piston pin of a piston; a lower link connected to the upper link via an upper pin having a center, the lower link being connected to a crank pin of a crank shaft; a control shaft extending substantially in parallel with the crank shaft, the control shaft having a rotational center; and a control link including: a first end swingably connected to the control shaft, and a second end connected to the lower link. In a process of the center of the upper pin moving nearer to the axial line of the piston pin, the center of the control pin moves in the upward direction, thus inclining the lower link and allowing the center of the upper pin and the center of the piston pin to move in the downward direction.

摘要： A multi-link piston crank mechanism for an internal combustion engine, including a crankshaft having a crank pin, and crank webs connected with each other through the crank pin. A pair of thrust surfaces are formed on the crank webs so as to be opposed in a direction of a center axis of the crank pin. A first link pivotally supported on the crank pin is coupled to a second link through a connection pin located in a space between the thrust surfaces. The connection pin is moveable about the crank pin to form a circular trace along which the thrust surfaces extend. The end surfaces of the connection pin and the thrust surfaces come into mutual contact to prevent the connection pin from falling out of the space between the thrust surfaces.
