Embodiment

With reference to Fig. 1, Fig. 2, be respectively side view and the plan view of the utility model structure, the rotor compressor 1 connected successively by high pressure pipe line 7, air compressing cylinder 2 and burning work done cylinder 3; The piston of air compressing cylinder 2 and burning work done cylinder 3 is connected by respective piston rod and bent axle 5 and realizes synchronously moving up and down of two-piston; Bent axle 5 is engaged with the rotor 11 of rotor compressor 1 by gear train 6 and realizes linking.

When the engine operates, rotor compressor 1 is sent to air compressing cylinder 2 after being compressed first by air, secondary compressed air to the high-pressure air secondary compression in its cylinder, then is sent to burning work done cylinder 3 and lights work done with fuel mix by the piston A23 in air compressing cylinder body 21.The piston B35 of burning work done cylinder 3 is with dynamic crankshaft 5 to rotate by piston rod B36, the piston rod A24 of air compressing cylinder 2 is connected with bent axle 5 equally, when the piston B35 in the work done cylinder body 31 that burns moves up and down, also the piston A24 in air compressing cylinder 21 is driven to be synchronized with the movement up and down, to the high-pressure air secondary compression in air compressing cylinder body 21 while rotating with dynamic crankshaft 5.Bent axle 5 is also engaged with the rotor 11 of rotor compressor 1 by gear train 6, when bent axle 5 rotates, is rotated by the rotor 11 in gear train 6 rotor driven compressor 1, and rotor 11 is compressed the air entered first by the cavity rotating formation and modification.

High pressure pipe line 7 between rotor compressor 1 and air compressing cylinder 2 is provided with pressure adjusting spring piston 4 to ensure that the compressed air pressure in high pressure pipe line 7 is stablized: when the pressure of high-pressure air increases, and the capacity of pressure adjusting spring piston 4 Inner increases and reduces pressure; When the pressure of high-pressure air reduces, the capacity of pressure adjusting spring piston 4 Inner also reduces and supercharging, and the nominal pressure of the burning work done cylinder 3 Inner high-pressure air of final guarantee motor is stablized.

With reference to Fig. 3, for the initial air-suction state after burning work done, the piston 35 of now burning work done cylinder 3 is positioned at the lower dead center of stroke under the active force of inner detonation, be in lower dead center equally with the piston 23 of the air compressing cylinder 2 of combustion cylinders 3 synchronized stroke, suction port valve 22 is opened, and the high-pressure air of rotor compressor 1 is input in air compressing cylinder 2 by high pressure pipe line 7.
