Building a rotary piston engine

In summary: The rotary piston engine is a type of engine that uses a single piston vane to spin a rotor. This engine is very efficient because it can convert heat energy into direct output of mechanical work. The engine is designed to use a very high heat pressure, which allows it to generate a lot of torque.

This project is a basic 6 inch rotary piston engine.

The rotary engine project is to build a external combustion chamber that will redirect the expanding heat into a rotor housing and turn a rotor with a single piston vane 340 degrees to the exhaust port.

The basic piston,rod and crank compresses air/fuel mixture into a chamber that allows the combustion heat energy to move into the rotary housing to spin the rotor.

This is the most efficiency way to convert heat energy into direct output of mechanical work.

I'm at the first stage of building the housing and rotary assy.

This is the data of the housing/rotor

Rotor size: 6"diameter x 2"width...area ((3^2*pi)*2)=56.55cu/in
Housing size: 7" inner diameter x 2" width...area ((3.5^2*pi)*2)=76.97cu/in
Piston vane: .5" x 2" or 1in/sq

The total piston stroke at 360 degrees (((3.5^2*pi)*2)-((3^2*pi)*2))=20.42cu/in or334.62cc
The piston has a 340degree power stroke before it enters the exhaust port and 20 degree after the combustion port, or a total if 320 degree of mechanical work.

(20.42/360deg)*320deg= 18.15cu/in total displacement of mechanical work in the rotary housing.

Combustion chamber is 1 cu/in in area.
Compressor pump 2.5" diameter piston x 2.25 stroke

The combustion chamber is a special design port that stores the max pressure to a limit of 150psi, after combustion of fuels the expanding port is redirected into the rotary housing, that then move the rotor forward.

This is the only engine that can can convert heat energy at TDC, into direct output of torque.


Max heat pressure 2000+psi
max output of torque (1000*3inch crank)=3000in/lb

I don't know what the true output of torque would be when this is finished.

This is what the engine will look like:

1. How does a rotary piston engine work?

A rotary piston engine works by using a series of pistons that rotate within a chamber, creating a continuous cycle of compression, ignition, and exhaust. This rotation creates a smooth and efficient transfer of power to the engine's crankshaft.

2. What advantages does a rotary piston engine have?

Some potential advantages of a rotary piston engine include higher power-to-weight ratio, smoother operation, and potentially fewer moving parts compared to traditional piston engines.

3. What are the main components of a rotary piston engine?

The main components of a rotary piston engine include the rotor, housing, eccentric shaft, and spark plugs. The rotor is the rotating part of the engine that contains the pistons, while the housing is the stationary part. The eccentric shaft connects the rotor to the crankshaft, and the spark plugs ignite the fuel mixture within the engine.

4. How is a rotary piston engine different from a traditional piston engine?

A rotary piston engine differs from a traditional piston engine in its design and operation. Rather than using a reciprocating motion of pistons, a rotary piston engine uses a rotational motion, resulting in a more compact and potentially more efficient engine.

5. What are the potential drawbacks of a rotary piston engine?

Some potential drawbacks of a rotary piston engine include higher production costs, potential sealing issues due to the rotating components, and limited fuel efficiency compared to other engine types. Additionally, the unique design of a rotary piston engine may require specialized maintenance and repairs.
