Fuel economy system for internal combustion engines

Abstract

A mechanical process for significantly improving the octane rating performance of gasoline powered engines (either conventional carburetion or fuel injection). An auxiliary system fractionates a precise portion of the required fuel and combines the fraction thus formed with a conventionally produced air/fuel mixture in states and proportions which optimize the combustion process. Different means of implementing the process are described utilizing an additional fuel controller which is connected to a fuel supply through an existing fuel pump which delivers fuel to both the fuel controller and an existing carburetion of fuel-injection system. Air for both is drawn through a common air filter. A proportioning system determines the proper amount of air and fuel entering the controller where they are mixed. The vapor fraction is enhanced and stabilized by passing the mixture through a heat exchanger. This vapor-rich mixture is then combined with the air/fuel mixture supplied by the existing system, and introduced into the engine's manifold. Precise control of the vapor fraction permits highly efficient combustion heretofore attainable only with chemical additives, such as tetraethyl lead.
