Abstract
A combustion engine is disclosed having a cylinder with a piston travelling through same, coupled by means of a piston rod to a crankshaft, wherein the piston rod has: —a first hub in its head for coupling with the crankshaft; —a second hub in its foot substantially aligned with or parallel to the first hub in the longitudinal direction of the cylinder when the crankshaft is in the upper or lower position; and —a third hub in its foot, which is offset laterally towards the front with respect to the second hub in the direction of rotation of the crankshaft; —the piston being coupled with the third hub, —having a guide for the travel of the piston rod coupled with the second hub, and —the piston being coupled with the third hub via a link rod.
Claims8
A combustion engine of the type that comprises at least one hollow cylinder, inside of which a piston travels in a linear reciprocating motion, coupled by means of a piston rod to a crankshaft, wherein the piston rod comprises:
- a first hub arranged in its head for coupling with the crankshaft,
- a second hub arranged in its foot, and which is substantially aligned with or parallel to the first hub in the longitudinal direction of the cylinder when the crankshaft is in the upper or lower position, and
- a third hub also arranged in the foot of the piston rod, which is offset laterally towards the front with respect to the second hub in the direction of rotation of the crankshaft;
- the piston being coupled with the third hub to reach the top dead center TDC when the piston rod is advanced in the advance direction of the crankshaft,
- comprising a guide to guide the travel of the piston rod through the cylinder coupled with the second hub, and
- the piston being coupled with the third hub via a link rod in order to enable a clearance between the piston and the guide during the reciprocating motion.
