Abstract
An internal combustion engine has an intake for air and for liquid fuel to be combusted, and an exhaust manifold for combustion gases. A closed casing is adapted to contain a quantity of the liquid fuel and a first conduit connects the interior of this casing with the exhaust manifold so that combustion gases from the latter are admitted into the closed casing. Baffles in the casing force the combustion gases to travel through the liquid fuel therein, to become enriched with the fuel, whereupon the thus-enriched combustion gases are returned via a second conduit to the intake of the internal combustion engine to become mixed with the incoming air and liquid fuel and to undergo another combustion cycle in order to fully combust any residual uncombusted matter.
