Abstract
Abstract Fuel feed apparatus for internal combustion engine characterized by the coactive disposition of fixed injectors and valves, interposed between fuel tank, pump, and carburetor of the engine. The principal component of the invention comprises plural fixed injectors in the fuel feed line, having the effect of substantially fully atomizing the fuel under control of in-line valves, whereby to feed the carburetor with a prepared mist of fuel under constant pressure thereby creating a substantial economy in the operation of the engine and a great saving in fuel.
