Diesel Generator Sets Emission Regulations Applicable for Engines up-to 800 kW

Test Cycle: D2 Mode Cycle as mentioned under ISO 8178

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 table (CPCB – Phase I) summarizes the standards that became applicable in 2004/2005, and Table (CPCB – Phase II) lists the strengthened limits applicable from April 2014

Ministry of Environment and Forest had issued a notification GSR 771 (E) dated 11th December, 2013 regarding the Emission Standards (CPCB Phase II) for New Diesel engines upto 800 kW for generator set (Genset application) which was effective from 1st April, 2014.

Further the implementation was amended vide GSR 232 (E), 31st March 2014 and made effective from 1st July, 2014. Subsequently, the certification requirements (Type Approval and COP for each COP year, for all engine models being manufactured or, for all engine or product models being imported) also revised from 1st July, 2014 and 1st July, 2015.
