Diesel engine dual path exhaust cleaner and burner system

TLDR
In this article, 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.
Abstract
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.
