Stark, T L

An exhaust cleaner and burner system for diesel engines provides for the trapping of particulates in the engine exhaust gases by their passage through a filter element. Collected particulates on the filter element are incinerated by the use of a heater means with the necessary air required for combustion of the particulates being drawn through the filter element by engine vacuum in the intake manifold of the engine. By throttling the air flow into the intake manifold so as to maintain a substantially constant depression therein, the required fuel burner mixture air flow needed for the combustion of carbonaceous particulates collected on a filter element is obtained during engine operation.
