Abstract
The intake manifold for supplying air-fuel mixture from a single source to a plurality of cylinders of an internal combustion engine employs individual pipes all having the same cross sectional area but having different non-circular cross sectional contours. Where less fuel is needed at low engine speed and power output, the bottom half of each intake pipe is formed with a smaller internal radius of curvature than the top half. Where more fuel is needed at low engine speed and power output, the bottom half of each pipe is formed with a larger internal radius of curvature than the top half. The purpose is to better equalize the distribution of fuel to the cylinders under low speed and low power operation of the engine, without affecting fuel distribution at higher engine speeds.
