Simplicity, Reliability and Modularity of Turbo Components

Classical piston engines have quite complex structure and have lots of parts which expose to high pressure and temperature. Unlike piston engines, the new engine is optimized to get maximum kinetic energy conversion and minimum losses thanks to air inlet, compressor, combustion chamber and exhaust as parts of novel thermodynamic cycle.

Pars Rotary Vane Engine contains six moving parts theoretically which are two vanes (one for the compressor and one for the turbine), two rotors (compressor and turbine rotors are connected directly) and tow valves. This reduces production, assembly and maintenance cost and also increase safety of the engine considerably.

Unique Fuel Efficiency

High fuel efficiency is obtained by the following methods:

  • The novel engine not only provides high pressure compression ratio but also provides advantages of Otto Engines’ heat input with constant volume, Diesel Engines’ heat input with constant pressure and Brayton Engines’ complete expansion capacity.
  • Lean and efficient combustion within the flammability limits.
  • Highly efficient aerodynamic design of compressor, burner and turbine components.

Power and Torque

Pars Rotary Vane Engine consists of two power phases in each cycle which is four times more than the ones of classical piston engines. With weak dependence of rotational speed, high torque is produced at almost every speed. This is useful for small engines. In summary, Pars Rotary Vane Engine can produce high power and torque per unit mass of the engine.
