Abstract
An internal combustion engine includes a crankcase, a cylinder, a piston, a crankshaft, and a piston connecting rod. A counterweight connects to the crankshaft through a counterweight connecting rod. The counterweight pivotally connects to the crankcase. The engine is constructed such that the crankshaft drives the counterweight less than 180 degrees out of phase with the motion of the piston. A center of gravity of the crankshaft is offset from the crankshaft's axis and moves out of phase with the piston by less than 180 degrees. The offset counterweight and crankshaft balance out inertial forces in the engine to reduce engine vibrations and improve engine performance.
