Method and apparatus for utilizing ethanol of any purity as a fuel in 4-stroke internal combustion engines

摘要

A method and apparatus for thoroughly mixing ethanol and air in the right proportion for efficient combustion in the engine consisting the active steps of aspirating the air by means of the vacuum pressure developed by the piston displacement of the engine in the intake stroke; bubbling said air into the liquid ethanol thereby evaporating said ethanol; mixing them in a homogeneous air-fuel flammable mixture; and introducing the mixture into the engine's intake manifold.
