A dual filter element exhaust cleaner and burner system for diesel engines provides for the trapping of particulates in the engine exhaust gases by their passage through filter elements, as selectively controlled by means of a four-way valve. Collected particulates in a non-active particulate filter element are incinerated by means of a heater, with this filter element, during incineration, being supplied with exhaust gases through a constant flow exhaust gas regulator whereby incineration of the particulates will occur at a controlled rate independent of engine speed.

A dual path exhaust cleaner and burner system for use with a diesel engine, said system including an exhaust passage for receiving spent combustion products exhausted from the engine; a four-way valve means having a first inlet connected to said exhaust passage, said valve means also having a second inlet opposite said first inlet and opposed first and second outlets with a movable valve for the selective control of flow from said first and second inlets to said first and second outlets; a secondary passage means connected to said second inlet; first and second housing means each having a gas inlet connected to said first and second outlets, respectively, and each having a gas outlet therefrom; first and second particulate trapping filter means of combustion resistant material operatively positioned in said first and second housing means, respectively; heating means operatively associated with said particulate trapping filter means to effect the incineration of particulates collected thereon during operation of the engine; and, a regulated flow exhaust passage means, including a constant flow valve means, connected at one end to said secondary passage means and connectable at its opposite end to said exhaust passage whereby a constant predetermined flow of exhaust gas, as controlled by said constant flow valve means, can be supplied to one of said particulate trapping filter means so as to effect a controlled complete incineration of particulates thereon.
