| Cleaning forced-air furnace ducts may also help decrease airborne recirculation of dust, as may high-efficiency air filtration. |
| The combustion chamber environment is very air-rich and the rotors have a lot of overlap to promote exhaust gas recirculation. |
| An additional stabilizing feature within our Plasma unit is the recirculation of heated mass, in a vorticular fashion within the Plasma flow. |
| The sludge generated from backwashing the filters is sent to a spent washwater tank for recirculation through the facility to minimize waste. |
| A system of vents allows for precise temperature adjustments and the recirculation of air. |
| By placing a cam phasing system on the camshaft, a pushrod engine can be tuned to take much higher levels of exhaust gas recirculation. |
