An internal combustion engine having one or more pistons (4), each of which is mounted to reciprocate in a respective cylinder (2) and is pivotally connected to a connecting rod (6) which is connected to a respective crank (10) on a crankshaft (7). The connecting rod (6) is pivotally connected to one end (11) of an elongate link (14) which is pivotally connected to an associated crank (10) at a point intermediate its ends and whose other end constitutes a rod (18) which is restrained by a mounting (20, 26) such that it may pivot about a pivotal axis (21) parallel to the axis (8) of the crankshaft (7). The mounting includes a first movable mounting member (20) connected to a second movable mounting member (26) to be pivotable with respect thereto about the pivotal axis (21). The first movable mounting (20) is connected to the rod (18) by a connection with permits only relative sliding movement in the direction of the rod (8). An actuating device (30, 32) is connected to the mounting and is arranged to move the mounting selectively in a first direction perpendicular to the axis (8) of the crankshaft (7) and in a second direction perpendicular thereto.
