Fuel vaporizing heat exchanger for an internal combustion engine

摘要

Heat is rapidly conducted to the induction manifold from the exhaust manifold via heat pipes, the heat absorbing ends of which have exhaust gases controllably directed thereagainst by a bimetallic operated butterfly valve and the heat emitting ends of which can be formed with, fins hollow or solid to increase the surface area thereof which contactingly and radiatingly heats all of the air fuel mixture passing through the induction manifold.
