The reciprocating piston engine can generate a power stroke from the left and right sides of the piston M378303*; When the program occurs on the left side of the piston unit (52), the piston unit (52) and the connecting rod (54) are pushed to the right. · When the combustion program occurs on the right side of the piston unit (52), the piston unit (10) and the connecting rod (54) will be pushed to the left; so when the combustion program is executed alternately on the left and right sides of the piston unit (52), the piston unit (52), the connecting rod (54) and the rack drive unit (55) will be left and right. The reciprocating motion, and the spring (10) disposed on the two sides absorbs the moving energy generated by the movement of the piston unit (10), the connecting rod (54) and the rack driving unit (55) and assists the piston unit (52) to return parallel displacement. /When the piston unit (52) makes a reciprocating displacement motion through the connecting rod (9) and the rack drive unit (55) 'Because the driving wheel set is coupled with the gear output unit ((6)', so when the rack drive unit (55) drives the gear When the output unit (56) rotates in the forward and reverse directions, the driven wheel set is also output in a single direction to the shifting mechanism' to provide driving use.
