摘要： A multi link type piston-crank mechanism comprises an upper link that has one end pivotally connected to a piston of the engine through a piston pin, a lower link that is pivotally connected to the other end of the upper link through an upper pin and rotatably disposed on a crank pin of a crankshaft of the engine; and a control link that has a base end part swingably held by a body of the engine and a leading end pivotally connected to the lower link through a control pin. An axis of the piston pin is offset relative to an axis of the piston in thrust and counter thrust directions. When the piston comes to BDC, a part of the piston takes a position below a lower edge of a corresponding cylinder of the engine and the upper pin is offset relative to the axis of the piston pin in the same direction as a pin offset direction in which the axis of the piston pin is offset in the thrust and counter thrust directions relative to the axis of the piston.

摘要： In a reciprocating piston engine employing a variable compression ratio mechanism (20) configured to be linked to a reciprocating piston (9) for variably adjusting a geometrical compression ratio by varying at least a top dead center position of the piston (9) responsively to a controlled variable, a controller (39) is configured to control the variable compression ratio mechanism (20) depending on an engine operating condition. A part of a wall surface of a combustion chamber (62) is formed of a non-metallic material (55,56;55,71a) having a higher heat-insulating and heat-reserving property as compared to a base structural material of each of the combustion chamber (62) and the piston (9).
