Description of the Anyoon Rotary Engine

This is anew type of Heat Engine / IC engine. This engine is rotary in type but different from existing ones. The major components of this engine are Rotor, Casing, and Valves.

Rotor: Rotors shape is shown in figure with a drive shaft at center. The width of the top of the is in such away that it seals the gap in the casing and the thickness of it is in such away that the opening in the combustion chamber can be completely sealed when it comes in line with it.

Casing: Casing is shaped like a hollow cylinder with sides closed and opening in the side for drive shaft. This provides complete sealing between rotor and casing. It has two combustion chambers with an opening into the cylinder and there is a spark plug / injector inside combustion chamber.

Valves: There are 4 valves in this engine. They block the gap between rotor profile and casing and is operated by a groove cam integrated to rotor

Working Of Anyoon Rotary Engine

Rotor rotates counter clockwise, as lobe1 crosses intake stopper1, intake stopper1operates inwards and intake takes place between intake stopper1, lobe1 and intake flange of rotor as shown in figure1 (blue letter i shows intake). Intake continues in figure2, exhaust port2 is closed by intake flange of rotor. Then as lobe1 crosses intake stopper2 intake stopper2 operates inwards, compression takes place in combustion chamber1 between intake stopper2 and lobe2 of rotor as shown in figure3 (blue letter c shows compression). Then as lobe2 closes combustion chamber1 ignition takes place. Constant volume heat addition takes place until the whole width of lobe2 crosses combustion chamber1. Then as lobe2 crosses exhaust stopper2; exhaust stopper2 operates inwards and power stroke takes place between exhaust stopper2, lobe2 and exhaust flange of rotor. Then water is injected in combustion chamber, water vaporizes and pushes rotor. In figure1 power stroke continues (red letter p shows power stroke of same cycle). Intake port2 is closed by exhaust flange of rotor. In figure2 exhaust is happening through exhaust port1. In figure3 as lobe2 crosses exhaust stopper1; exhaust stopper1 operates inwards and exhaust is happening between exhaust stopper1 and lobe1; through exhaust port1. Thus one cycle is completed in 2 revolutions of rotor for combustion chamber1. Similarly another cycle is happening in combustion chamber2. Two cycles per revolutions are completed per revolution of rotor since at any time four phases of four different cycles are present simultaneously at four different compartments of the rotary engine.

Since we have control over injected water suitable additives can be added to prevent corrosion like alkaline materials to neutralize acid formation.

Materials used for prototype are Aluminum alloy LM25 for casing, rotor, cover plate and stoppers; Furnace steal for combustion chamber inserts; Stainless Steal SS304 for Seals with special coating like– Diamond-like-Carbon coating. High temperature aerated silicone rubber compound for rubber strip in the seals. Spring steals for springs.
