THE INNOVATIVE DESIGNING OF THE CONNECTING-ROD SWINGROD GEARDRIVING INTERNAL-COMBUSTION ENGINES

ABSTRACT: Aiming at the current problems like short drive arms and low mechanism efficiency existed in the crank connecting rod piston internal-combustion engines, the paper proposes a design of a kind of connecting-rod swing-rod gear-driving internal-combustion engine that can convert two reversal thrusts of the piston linear reciprocating motion into two reversal torques of the swing rod and then into one one-way torque by the gear sets. The maximum piston thrust F are highly converted into the shaft torsion Ft, which makes the connecting-rod swing-rod gear-driving internal-combustion engines’ maximum shaft torque increase by about 34% than that of the crank engines. What’s more, the effective fuel consumption rate is reduced. The connecting-rod swing-rod gear-driving internal-combustion engines directly use the mature technology of the traditional internal-combustion engines’ straight reciprocating piston structure to trial-manufacture the prototypes and produce in enormous quantities. Production difficulty will be less than ever. The internal-combustion engines’ environmental performance is improved.
