Automotive engine exhaust-clean air system

Patent ·
OSTI ID:5258516
A description is given of an internal combustion engine of the spark or diesel ignition type having an anti-pollution arrangement for the reduction of the products of incomplete combustion and crankcase evaporation. The arrangement includes a turbine adapted to receive exhaust gases connected to the engine through an overriding clutch to drive the turbine yet allowing for overriding faster rotation of the turbine through secondary ignition of the exhaust or other unburned gases. The turbine includes a fuel supply to aid in ignition of exhaust gases and may include a fuel supply with an aromatic indicator fluid which loses its aroma upon oxidation at a predetermined temperature thereby indicating if the turbine temperature is high enough to completely eliminate unburned exhaust and other gases without recycling said gases through the engine.
