A driving engine for vehicles has at least two cylinders (2a, 2b) aligned with one another and engaged by respective pistons (7a, 7b) in a sliding manner, each of which is connected with a crankshaft (8) by means of the interposition of a connecting rod (1...

A double crankshaft internal combustion engine is proposed with at least one cylinder in which a reciprocating piston is arranged to move back and forth. The engine has a first and a second crankshaft, wherein the two crankshafts run parallel to each other...

In a premixed compression self-ignition engine which is compact but capable of exerting a high output, an intermediate portion of a trigonal link is rotatably supported on a crankpin, a large end portion of a connecting rod is connected to one end portion ...

The present invention provides a stirling engine, which is capable of reducing a frictional loss and eliminating possibility of deterioration of a heat exchanger due to lubricant oil applied to piston rings and the like. The stirling engine includes cylind...

The object of this invention is to improve the characteristics of the normal crank mechanism that is universally adopted on the internal combustion engines and reciprocating compressors to transform the reciprocating motion of the piston into the rotationa...

The invention provides a variable compression ratio engine that has a simple structure, easily ensures the sealability, and provides high reliability. In a variable compression ratio engine, a connecting rod 13 converts vertical movement of a piston 6 in a...

A Stirling engine (1) comprises four working pistons (3) all at right angles and a planetary drive (4) to convert to a drive shaft (5) rotation via an external toothed crank (11). Two equalizing masses (14,14') equalize mass forces and moments so that the ...

Control arms (16,17) are connected to corresponding cross levers (14,15) to adjust the compression ratio of cylinders (2c,3c). Piston rods (12,13), pivotally connected to one end of corresponding pistons (19,20), are rotatably supported by the cross levers...

In a piston actuation system of a V-type internal combustion engine with two cylinder banks having at least one pair of cylinders, a piston pin, an upper link, a lower link, and a control link are mechanically linked to each other for each cylinder bank. W...
