ABSTRACT:
An exhaust cleaner system for use in the exhaust system of a diesel engine is provided with a particulate filter positioned in a trap housing with an exhaust inlet thereto and an exhaust outlet therefrom. A pair of exhaust ducts are positioned in the inlet end of the exhaust outlet whereby to define, in effect, three separate exhaust flow zones through the filter and a flow limiter valve is operatively positioned to sequentially control flow through the exhaust ducts. Glow plugs are located so as to extend into the zones of the filter associated with the exhaust ducts to initiate incineration of particulates during reduced exhaust flow conditions as controlled by the flow limiter valve.
