An internal combustion engine for automotive vehicles of high performance has a very high cylinder bore to piston stroke ratio and two piston rods (2) engaged with the same piston, which actuate two counter rotating crankshafts (4) engaged through gears (5) with 1:1 driving ratio, so that the large surface of the piston head (6) enables the arrangement of particularly efficient valve and combustion chamber systems combined with an efficiently balanced engine. |
