The environmental impact of internal combustion engines has led to increasing governmental regulations regarding the emissions and fuel economy performance of internal combustion engines. The DI Diesel engines, having the evident benefit of a higher thermal efficiency than all other engines, have served for both light- duty and heavy-duty vehicles. But, direct injection diesel engines emit more particulates and oxides of nitrogen than their counterpart and that is a challenge. The NOx+HC limits for CEV BSIII regulations is 4.00 g/ Kw-Hr,3.8 g/Kw-Hr with deterioration factor[DF] against the 10.50 g/Kw-Hr of CEV BSII regulations, which is over 60% reduction in gaseous emissions. Now after this stringent targets defined it is essential to understand the NOx formation.
