ABSTRACT:
An air-fuel inlet device for an internal combustion engine characterized by a spacer having passages therethrough with spaced parallel annular recesses formed in the side walls of the passages.
The spacer is positionable between a carburetor and an intake manifold of an engine with the passages establishing communication between the outlets from the carburetor and the inlets to the manifold. It has been found that when the spacer is substantially one inch thick, and the annular recesses are essentially square in cross section and have a width and depth of substantially 1/16 inch and a spacing of 1/16 inch along the passages, engine efficiency is significantly increased, fuel consumption is decreased, and exhaust emissions are significantly decreased.
