ABSTRACT:
An offset crankshaft mechanism for an internal combustion engine which allows for greater efficiency and increased torque. The invention includes an engine block, a crankcase, one or more piston cylinders each having a piston reciprocally disposed therein, a rotatable crankshaft longitudinally disposed within the crankcase and offset at a predetermined distance from the vertical axis of the piston cylinder, and one or more connecting rods connecting the pistons to the crankshaft. The offset crankshaft is located such that at a point during the power stroke the crankshaft is perpendicular to the vertical axis of the piston cylinder and the connecting rod is substantially collinear with the vertical axis of the piston cylinder. The crankshaft must be located far enough below the piston cylinders to prevent interference between the connecting rods and the piston cylinders. Long connecting rods are used to increase the efficiency of the engine by increasing the combustion chamber pressure at top dead center, and reducing the return stroke angle which reduces the friction between the pistons and the piston cylinders.
