In order to achieve the above object, the utility model is to be achieved through the following technical solutions:

A kind of motor, comprise four groups of engine devices, engine device comprises inner carrier 2, outer piston 3, suction tude 8, steam outlet pipe 9 and with the cylinder 1 of oil nozzle 4, inner carrier 2 is sleeved on outer piston group in the interior composition of outer piston 3, two ends, the interior left and right of cylinder 1 are set with interior outer piston group, suction tude 8 and steam outlet pipe 9 are inserted in respectively in the interior outer piston group at two ends, left and right, on the outer piston 3 at two ends, left and right, be respectively arranged with connecting ring 5, two connecting rings 5 are connected to respectively the two ends of bent axle 7 by piston brace rod 6, be provided with driving gear 12 on bent axle 7; Above part forms cylinder block, and the single or single above acting of cooperation together of cylinder block, is provided with engine housing 10 and lower engine housing 11 on cylinder block outside; Single above cylinder block connects by piston brace rod 6.

On described cylinder 1, be provided with spark plug, fuel pressuring device.

Described cylinder 1 arranges cooling or thermal insulation apparatus.

On described engine air inlet tube 8, air inlet boosting device is set.

Between described inner carrier 2, outer piston 3 piston brace rods 6, connecting ring 5, bent axle 7, lubricating fitting is set.

Described external engine is provided with starter.

Compared with prior art, the utlity model has following useful technique effect:

The utility model is by add starter inside and outside motor, spark plug, and fuel feeder apparatus, air inlet boosting device, cooling or thermal insulation apparatus, lubricating fitting, also can according to circumstances adjust fuel, conveniently uses and keeps in repair.By outer piston group in two groups is set in the cylinder of engine device, and suction tude and steam outlet pipe be set respectively in outer piston group in two groups, motor is externally under the effect of supercharging device, a side pressurization to suction tude, gap while making air by inner carrier and outer piston folding enters, thereby saved the application to gas handling system in prior art, simplified the structure of motor, dwindled its volume, improved the reliability of motor, its maintenance and popularization have been facilitated, while is due to the set-up mode of suction port in this motor, the tolerance that enters cylinder is increased, thereby make the even of fuel and gas mixing, and then improved and compressed the when rate of combustion of fuel, raising due to rate of combustion, and improved the mechanical efficiency of motor, reduced the severe contamination that tail gas that motor emits produces environment.

Embodiment

Below in conjunction with accompanying drawing, model utility is described in further detail:

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of motor, comprise four groups of engine devices, engine device comprises inner carrier 2, outer piston 3, suction tude 8, steam outlet pipe 9 and with the cylinder 1 of oil nozzle 4, inner carrier 2 is sleeved on outer piston group in the interior composition of outer piston 3, two ends, the interior left and right of cylinder 1 are set with interior outer piston group, suction tude 8 and steam outlet pipe 9 are inserted in respectively in the interior outer piston group at two ends, left and right, on the outer piston 3 at two ends, left and right, be respectively arranged with connecting ring 5, two connecting rings 5 are connected to respectively the two ends of bent axle 7 by piston brace rod 6, on bent axle 7, be provided with driving gear 12, above part forms cylinder block, and the single or single above acting of cooperation together of cylinder block, is provided with engine housing 10 and lower engine housing 11 on cylinder block outside, single above cylinder block connects by piston brace rod 6.
