As Fig. 2, shown in Figure 3, axisymmetric is evenly equipped with six cylinders that axially connect on the described cylinder block.
Working procedure of the present utility model is as follows: compression (air inlet) stroke: two-piston 2-02 is to the operation of cylinder middle part, the inlet and outlet valve 4-06 of both sides closes the inlet and outlet hole with piston 2-02 under the effect of valve top spring 4-02, the air of piston 2-02 rodless cavity is compressed.And two-piston 2-02 rod chamber also sucks fresh air (air is that one-way valve-inlet hole enters through air-strainer-suction valve 4-13).Because of intake stroke=scavenging stroke+working stroke, so admission space is greater than swept volume.
Work (scavenging) stroke: two-piston 2-02 is during to top dead center, and air is pressed into firing chamber 6-02, and the oil sprayer 6-03 oil spout in the 6-02 of firing chamber is also lighted a fire, and burns with fuel mix in strong motion.For the discharging that reduces Nox can be adopted slower firing time, and prevent the deterioration of combustion quality with twice strong air motion.In the descending work done of the gas effect lower piston 2-02 of High Temperature High Pressure.And the fresh air of piston 2-02 rod chamber is pressed into gas storage chamber 4-15 (air is one-way valve-intake elbow 4-10-gas storing pipe 4-11-enter gas storage chamber 4-15 through suction valve 4-14).When come downwards near the piston 2-02 of exhaust valve stroke 1/2 the time, exhaust valve is opened under the drive of this piston 2-02, waste gas is discharged cylinder down by self pressure.When exhaust valve opened to 1/2, intake valve was driven and is opened by the piston 2-02 near intake valve, and the fresh air in the gas storage chamber 4-15 enters cylinder and extrudes remainder of exhaust gas.Cause is ahead of the swash plate body 5-15 degree of hole one side of calming the anger at the swash plate body of sense of rotation upper air-vent one side of main shaft 3-01.Two swash plates have certain differential seat angle, and exhaust valve is opened earlier, and after scavenging was finished, the inlet and outlet door can be closed simultaneously.Firing chamber 6-02 on six cylinders lights a fire successively, work (scavenging) stroke and compression (air inlet) stroke are carried out in circulation, thereby promote two swash plate bodies and drive main shaft 3-01 rotation, intermediate gear 3-07, driven gear 3-08 and oil pump 5-02 in mainshaft gear 3-06 driven gear case 1-06, and externally providing power through belt pulley 3-13, the flywheel 3-14 that is fixed on the main shaft 3-01 the other end can guarantee the stable of the continuity of each cylinder air inlet, scavenging stroke and outputting power.
Inclined disc type two-stroke opposed pistons internal-combustion engine provided by the utility model, volume is little, and equal discharge capacity lower volume has only about 1/3 of crank engine.Mechanical strength and high working efficiency, the power of piston when compression and work acts directly on the main shaft, and piston has not had lateral force, good stability, long service life.
