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.

Despite the demonetization effect, passenger vehicle industry in India saw a humble growth of 2% in November 2016. Maruti(14.1%) and Hyundai(-8.3%) retained their 1st and 2nd positions respectively. Despite a slight degrowth in the sales of Alto, Swift and Dzire, Maruti is able to grow its market-share(52.2%) due to the sales of Vitara Brezza & Baleno. Maruti infact intentionally reduced(despite good sales) the production capacity of other models and phased out Ritz production to accommodate Baleno and Vitara Brezza.

Hyundai retained its second position though its market share declined from 17.8% in October to 14.3% in November. We have to wait for the model wise sales figures to come out to see what models did sell well and what models didn’t sell well for Hyundai Motors in November.

The other upcoming models from Tata Motors are sub 4 meter sedan Kite-5(codename), top of the line Tata Hexa and Tiago Sport & Aktiv.
