Equipment preventing formation of visible cloud of soot particles from diesel engines

摘要

The exhaust pipe includes a shut-off valve (8) with branch (5) ahead of it. This enters a cyclone separator (4) with container (11) for separated particulate solids. The particles can be re-mixed (14) with the exhaust gas flow through a line (7) and valve (9). A control unit (10) is wired (15,16) to switch the valves. A unit (18) signals the operational state of the engine to the controller. An Independent claim is included for the corresponding method.
