Abstract: An atomizer disposed between the carburetor and intake manifold for breaking up and intimately mixing the charge of fuel and air received from the carburetor before passing it on to the intake manifold of an internal combustion engine. The atomizer has a chamber with two motor driven paddles with parallel axles disposed within the chamber across the air flow. The paddle vanes are overlapping in operation and geared to rotate outwardly as viewed upstream of the paddles with very high turbulence to atomize the gas particles and provide an intimate mixture of air and fuel.
