IMPROVEMENTS IN EMISSIONS CONTROL |
摘要 |
A diesel engine (1) has an exhaust system (4) and an oxidation catalyst (5a). Exhaust gas for recirculation is taken through an intake pipe (6) downstream of the catalyst, and preferably upstream of a filter (5b) for soot. The recirculated gases are passed through a cooler (7) upstream of the EGR valve (8). Good removal of soot and NOx is achieved even at low exhaust gas temperature. |
