Rotary Engine 24-25
A new rotary diesel engine is offered. This device inclusive two rotary lobes which is presented in the name of rotary lobes 24-25.
The engine comprises 25 rotary cells created by two mated lobes . The engine act as a diesel engine with 25 cylinder.
A - Combustion air compression area
B - Fuel injection point (bore of injecting pressurized fuel)
C - Explosion and expansion area
D - Exhaust and purge area (purge the cells and cool down the lobes and charge combustion air by air turbocharger). The turbocharger is rotating strongly and fast by flue gas witch is forced out by contracting the cells.
Running the engine
- To run the engine, its input shaft rotates by means of a starter.
- Normally some air is trapped among the cells.
- During start process, in the compression region (A), trapped air will be compressed and heated up and therefore combustion air is prepared. This process will be continued consecutively while the engine is running, therefor it is not require to equip system with combustion air injection timing mechanism.
- Fuel (gas-oil) which is pressurized over than combustion air pressure,
injects into the cells via injection port located in TDC rejoin (B). While the lobes are rotating their lateral face teeth act as slide valve when passing in front of fuel injection port and open/close it consecutively, therefor it is not require to equip system with fuel injection timing mechanism.
- As each cells is passing out from TDC region (B), begin expanding and the mixture (fuel-air) explodes.
- High pressure cell tends to expand rapidly to releases the pressure and so the lobes rotate strongly.
- After running, the starter will be disconnected and the process continue indefeasible.
- Now the shafts are rotating strongly and the cells are expanding toward DDC region (K) and exhaust throat.
- While the cells are leaving DDC region, most of the pressurized flue gas blast via exhaust throat and through the turbo fan (G) and rotate it strongly then leave out via exhaust guid (E).
- Rotating turbo charger (G) will blow clean air for purging and cooling the cells and so prepare combustion air via manifold (I).
- Residual flue gas enters purge region (D) and not only purge with purge air but also forces out via turbo fan (G) and exhaust guid (E) to atmosphere.
- While the motor is running the motor casing cooled down by a fluid coolant which flow in via inlet (F) and flow out via outlet (H) and recycle after heat exchanging.
- Process will be continued until the explosion condition is available.
