Abstract: A means of continuously pressurizing an air/fuel mixture residing within a crankcase of a two cycle internal combustion engine is disclosed. The crankshaft fitted flywheel or counterweight of the engine is mounted with a plurality of vanes which extend from a central region of the flywheel outward to the periphery of the flywheel. The vanes are positioned over the entire surface of the flywheel. A ducting channel which receives a air/fuel mixture charge from the carburetor directs that charge to the central region of the flywheel. In operation the crankshaft rotates the flywheel causing the fuel charge to be uniformly hurled outward from the central region to the periphery of the flywheel. The forces acting on the charge serves to compress the mixture within the crankcase. At low engine revolutions as well as for starting the engine the conventionally accepted use of one way reed valve induction is used.
