摘要： In an internal combustion engine of variable compression ratio type, a piston control mechanism is employed which comprises a lower link rotatably disposed on a crank pin of a crankshaft of the engine, an upper link having one end pivotally connected to the lower link and the other end pivotally connected to a piston of the engine, a control link having one end pivotally connected to the lower link; and a position changing mechanism which changes a supporting axis about which the other end of the control link turns. When the piston comes up to a top dead center, a compression load is applied to the control link in an axial direction of the control link in accordance with an upward inertial load of the piston.

摘要： A crankshaft mechanism is disclosed that takes advantage of component makeup and orientation to cancel out inertial force. A crankshaft of the crankshaft mechanism includes at least one counterweight that is arranged in combination with the rest of the mechanism to cancel out the inertial force particularly at a timing in front of a bottom dead center of a piston where the inertial force becomes a maximum.

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 piston crank mechanism has an upper link coupled to a piston by a piston pin, a lower link having a crankpin journal, wherein the crankpin journal is coupled to a crankpin of a crankshaft and is coupled to the upper link by an upper pin, and a control link is coupled to an eccentric cam of a control shaft that is supported by an engine block and coupled to a control pin boss by a control pin. The crankpin journal of the lower link is arranged and dimensioned relative to the upper pin such that a projection area defined by projecting the width of the upper pin along a direction line passing through a center of the piston pin and a center of the upper pin does not obscure an area defined by the crankpin during operation of the crankshaft as viewed in an axial direction of the crankpin.
