Apparatus forming part of the induction tract of a piston internal combustion engine in which a minor part of the flow of induction air passes through heat-exchange means (47, 48) in which it is heated by exhaust gases above the boiling temperature of the engine fuel; said fuel being heated in heat exchange means and an atomised flow being discharged into and completely evaporated in said minor part of the flow of induction air, the resultant fuel-air mixture being combined with and thoroughly mixed with the major part of the flow of induction air prior to its entry into the engine inlet ports; said major part of the flow of induction air being optionally heated to regulate the temperature of the combined flow of induction air. |
