EGR

Cuir air ais Gasan Sgaothail. Fear de na teicneigeachdan smachd theàrnadh, anns a bheil gasan air an tarraing à phìoban sgaothail (mus an sgiorsa) agus air an cur air ais tro mhanifold an tomhais (gus an 'losgadh' a-rithist). tha an teòthas àrd a tha co-cheangailte ri gasan sgaothail a' dol a dhìth air meatailtean daor ... mar sin tha an t-siostam seo a' dol a dhìth air a dheànamh a-rithist no a chàradh a dh'fhàsdaidh.

Exhaust Gas Recirculation. One of the emission control techniques, in which gases are sucked from the exhaust pipes (before the muffler) and re-circulated through the intake manifold (to be 'burned' again). the high heat associated with exhaust gases required expensive metals ... so replacing/repairing this system can be costly.
