Emissions from new diesel engines used in generator sets have been regulated by the Ministry of Environment and Forests, Government of India. The regulations impose type approval testing, production conformity testing and labeling requirements. The regulations also include a list of authorized agencies for type approval testing.

Engines up to 800 kW. Emission limits for new diesel engines ≤ 800 kW used in genset applications were set in 2002 and strengthened in 2013. The regulations also set noise limits for diesel generator sets up to 1000 kVA.

The emission standards are listed below. Table 1 summarizes the standards that became applicable in 2004/2005, and Table 2 lists the strengthened limits applicable from April 2014.

Engines are tested over the 5-mode ISO 8178 D2 test cycle. Smoke opacity must not exceed the limits at full load (Table 1) or at any load point of the test cycle (Table 2). The same limits are applicable for type approval and for conformity of production (COP) testing.

Engines above 800 kW. Emission standards for new diesel engines above 800 kW used in genset applications were phased-in between 2003 and 2005, Table 3.
