3. motor local oxygen enriching device as claimed in claim 1, it is characterized in that: motor is in suction stroke: while piston (7) moves down from top dead center, air inlet door cam (1) top pressure air inlet door (3) moves down and opens air inlet door (3) and makes air enter in cylinder body (11), reach from air inlet door (3) air entered in cylinder body (11) design air inflow 1 to two/5th/for the moment, intake oxygen enrichment door cam (15) top pressure intake oxygen enrichment door bar (8) also opens intake oxygen enrichment door (4), oxygen-enriched air is made to enter in cylinder body (11), when piston (7) is moved down into lower dead center, air inlet door (3) and intake oxygen enrichment door (4) are closed simultaneously, the compression stroke of motor and expansion stroke: the mixed gas that piston (7) moves up in compression cylinder (11) from lower dead center, while piston 7 arrives top dead center, igniter (9) automatic ignition makes the air-fuel mixture gas by compressing burn, the mixed gas volume of burning sharply expands, produce comparatively high thrust promote piston (7) and move down, piston (7) is passed to lower dead center, and expansion stroke completes, the exhaust stroke of motor: while completing expansion stroke, to move up from lower dead center and simultaneously, exhaust valve (13) is opened by exhaust valve cam (17) top pressure, and the flue gas after burning is discharged from exhaust valve (13) at piston (7).
