A novel rotational internal combustion engine is invented and investigated. In this engine, no reciprocating component is used, resulting in vibration-free operation. This engine mainly consists of a rotor casing, a rotor and a crank shaft. The rotor shapes as single-lobe peritrochoid curve. The rotor rotates by the crank shaft of eccentricity e and rotates itself in counter-direction by phasing gears. The rotor casing shape is defined as envelope curve of the rotating single-lobe peritrochoid rotor. The room between the rotor and casing performs the working processes for working gas; intake, compression, ignition, expansion and exhaust processes. The intake of premixed gas of air and fuel and exhaust of burnt gas are controlled by rotary valve installed on the combustion recess of the rotor-casing. The combustion recess is equipped with spark-electrodes for ignition. One of advantages of this engine compared with Wankel rotary engine, is easy and reliable sealing of working gas. In this engine configuration, that is, a sealing component is only installed on waist section of rotor-casing, instead of complex sealing system on a rotor in case of Wankel engines, resulting in high efficiency by low-leakage of working gas. In this paper, first, configuration and geometries of this engine with single working room are described. Next the prototype engine is introduced and the cyclic behavior of the working process of this prototype engine is explained.
