After this motor is closed, independently in the position of this rotor 16,17, this upper beam 7 will decline due to gravitation together with bearing 10 with piston 6, remove aforementioned gap, and this protruding A will touch this rotor correspondence surface M, provide they without impact engagement and piston 6 displacement to open this air inlet window B.
This engine operation following (see Fig. 1 b, 2b, 3b, 4):
When startup, this flywheel 23 starts to rotate, and drives by an external source (such as: electromagnetic starter, air starter, kick starter etc.), and will rotate the gear 21 being sent to this rotor 16,17 and one ancillary equipment driver by this axle 20.By belt transport, this gear 21 drives this pressurized machine that air is pressed into this sleeve, such as, under the pressure of 1.4-1.5 kg/cm.Select this pressure range to be in order to compared with a common two-stroke internal combustion engine, its crank chamber has the similar pressure produced by its piston.When rotated, this rotor 16,17 is by the protruding A driven plunger 6 of this crossbeam 7.This piston mobile controls the gas of air and the discharge taken in.
The demonstration running of this rotor 17 is showed in fig 1 a, and in illustrated position, this piston 6 is positioned at upper dead center and closes this air inlet window B and this window D that gives vent to anger.In rotation process, this rotor forces this piston to move towards lower dead centre by this protruding A, and it causes opening this air inlet window B and this window D that gives vent to anger, and part fresh air is introduced in this sleeve under stress.
Afterwards, this rotor drives this bearing 10 to move towards upper dead center, and its bearing cuts out this air inlet window B, then closes this window D that gives vent to anger.Now, in the rotation of other 6 to 7 degree, this hole C(finds expression in Fig. 2 b) be still unlocked, it allows part fresh air to fill this sleeve 4, and fill factor is substantially equal to 1.0.Because this hole is the sidewall of this sleeve of tangentially aliging, so strongly rotated by generation air, improve the mixing of this fuel-air mixture.
In the rotary course of 180 degree, this piston arrives upper dead center, at sleeve compressed air.At a predetermined point, aforementioned upper dead center, the control unit of this pre-programmed transmits an order to inject fuel in the firing chamber of this sleeve.
Now, this fuel-air mixture is lighted, the stroke and this motor is started working.From at the moment, increase stressed air or gas is for good and all present in sleeve, until this motor is closed, its pressure makes the external bushing of this bearing 10 be compressed against the internal surface of this rotor 17 and the protruding A of this crossbeam 7 is separated with the internal surface of this rotor by piston 6 and crossbeam 7.
