Six-stroke rotary-vane internal combustion engine

A six-stroke rotary-vane internal combustion engine comprising:

• a stator having inlet ports and outlet ports, holes for spark plugs and working chambers for intake and compression of an air-fuel mixture alternating with working chambers for expansion and removal of combustion products;
• a cylindrical rotor rigidly fixed on a shaft and having side walls, the cylindrical rotor comprising longitudinal grooves housing blades, combustion chambers being formed on a cylindrical surface of the rotor between the grooves;
• front and rear end shields,
• side walls of all the working chambers of the engine are formed by rotating parts of the rotor,
• wherein the combustion chambers are formed as hemispherical recesses on the cylindrical surface of the rotor between the longitudinal grooves of the rotor, and
• the working chambers of the stator are formed as cylindrical borings with axes parallel to a stator axis, the borings being evenly spaced along an inner surface of the stator,
• each blade consists of separate plates freely displaceable relative to each other, each plate of the blade being made of two parts movable apart in an axial direction by a spring,
• wherein the number of blades is a multiple of the number of the chambers for intake of the air-fuel mixture.
