4.11.4.c Diffuser

The diffuser provides an increase in the air flow rate at its center and creates a vacuum at the end of the disperser, which is necessary for sucking fuel from the disperser and better atomizing it.

With the help of throttle blade one can change the flow passage of the hole for the air-fuel mixture and thereby regulate the amount of this mixture coming from the carburetor to the engine cylinder. The engine power and the number of revolutions of the crankshaft change in accordance with the amount of mixture entering the engine.
