Automotive engine exhaust -- clean air system

An internal Combustion engine having a combustion chamber and exhaust ports in communication therewith for discharging exhaust gasses -- the improvement comprising:

• a turbine having a housing with intercommunicating chambers including a front compression chamber, an aft burner chamber and an intermediate mixing chamber, means for compressing air in the compression chamber, means for delivering the compressed air to the mixing chamber, means for supplying a combustible gas mixture into said mixing chamber, means for igniting said combustible gas mixture in the mixing chamber, means for conducting the ignited gasses into the burner chamber, heat-transfer conduit means providing passage means for the exhaust gasses through said burner chamber isolated from the ignited gasses in the burner chamber for heating said exhaust gasses for substantial consumption of the exhaust gasses in the conduit means, and means for exhausting the spent gasses from said burner chamber and said passage means, said burner means completely enshrouding said conduit means and providing an enveloping thermal shield therefor.
