Fast-running IC piston motor has all the crankshaft bearings between the outermost crankshaft throws with one connecting rod for each throw to reduce the motor length without loss of power

摘要

In the fast-running piston motor, all the crankshaft bearings (23-26) are deployed axially between the two outermost throws (18,22) of the crankshaft, so that each of the axially outermost crankshaft throws (18,22) has a floating bearing. Only one connecting rod (12-16) is at each crankshaft throw (18-22).
