thermal reactor

thermal reactor
(TR)
[1] A high-volume thermally isolated chamber replacing the exhaust manifold and providing a place for high-temperature afterburning of exhaust pollutants. Found on all Mazda rotary engines and some piston engines (BMW for example) as well.
[2] A device installed in the exhaust manifold of some air injection systems to promote HC and CO oxidation by providing long exhaust gas residence times in a localized area.
[3] an emission control device that accepts raw exhaust gases from the engine and subjects them to extremely hi temperature to oxidize noxious emissions. Uses a specially designed exhaust manifold that uses heat and air to burn the unburned hydrocarbons in the exhaust gases to reduce pollution
