Classic two stroke valve-less petrol engine, which operates without added lubricating oil to the fuel-air mixture. The above mentioned invention is applicable in the motorcycle industry, automotive industry, water sports industry, mechanical industry and other industries which need and use engines to power machinery and equipment to perform their functions. The well known positive qualities of the current two stroke engine make it desirable in numerous applications and uses, however its two major drawbacks (pollution from exhaust gasses containing unburned oil and greater fuel consumption) limit the scale of its utilization. The invention design of the petrol two stroke engine allows for the exhaust gasses to comply with the acceptable pollution levels, to increase the power output of the engines (due to the fact that lubrication oil, which until present was required by the former design, is absent from the air-fuel mixture) and to reduce the fuel consumption. Another factor in improving the technical characteristics of the engine is the embedded rotor plate/vane compressor which has the optimal capability for air induction at low, as well as at high rpm (rotations per minute). The optimal efficiency of the engine is achieved with the assistance of additional mechanisms and electronic devises for regulation of the air flow to the cylinder.
