WELCOME TO DOROTHYThis patented EGR cleaner is the first of its kind! The Dorothy Tornadic ERG Cleaner removes heavy soot particles from the EGR system gasses and feeds the cleaner gases back into the engine which lowers NoX, decreases DEF usage, and increases your engines efficiency.
Dorothy EGR cleaner installed on a Cummins engine.

HOW DOES DOROTHY WORK?
This heavy soot mix enters the unit at the entry inlet (1) and flows into the torus (2) where it spins around 360 degrees while the engine is at full load. The heavy particles remain in the outside diameter of the torus filter (2) until EGR flow is low or nonexistent.
|
Each time the driver removes their foot from the accelerator the decreased EGR flow causes the particles to fall through the dropout gap (3) and into the collection pot (6).
The distance between the dropout gap and the collection pot is large enough to allow the lighter clean gases to rise up through the pass-through (4). The clean exhaust gases exit top of the unit through the outlet assembly (5) and back into the engine intake. |
