Abstract (en)

[origin: WO8705359A1] An internal combustion engine operating on a two-stroke cycle principle including a unitary piston arrangement comprising a combustion piston (4) operating in a combustion cylinder (1) and a compression or pumping piston (5) operating in a compression cylinder (2), the compression piston having a larger diameter than the combustion piston, and a connecting assembly comprising a piston rod (10), a gudgeon pin (12) fixed in the piston rod eye (11), the outer ends of the pin being rotatably accommodated in a cylindrical crosshead (15) coaxial with the piston rod and reciprocating with the pistons (4, 5) within a bore (16) in the crankcase casting (17). The assembly (10, 12, 15) connects the piston arrangement (4, 5) to the crankshaft (14) mounted in the crankcase (17) via connecting rod (13) and a dividing wall (28) is provided whereby the cylinders (1, 2) are isolated from the region surrounding the crankshaft (14) within the crankcase (17).
