Indian Standard for vehicular pollution

International Emission Standard for Vehicular Emission fall into three categories:
1. European Emission system (EURO SYSTEM).
2. Japanese Emission system.
3. American Emission system.

The European Emission Standards are followed by most of the countries, including India.

EURO-I are those that should have been applicable from year 2000.
EURO-II- are those that should have been applicable from year 2005.

The Central Motor Vehicles Rules-115(II) 1989 says that the pollution standards laid down for carbon monoxide and inspected in petrol vehicle should be as under :

2 and 3 wheelers - Idling Carbon Monoxide emission by volume:4.5%
4 wheelers - Idling Carbon Monoxide emission by volume : 3.0%

For Diesel Vehicles the emission standards for inspection of smoke density are as under:

Maximum Smoke	Density
	Light absorption co-efficient (l/m)	Bosch Units	Hartidge Units
(i) Full load at 60 to 70% of maximum engine rated rpm declared by the manufacturer.a	3.25	5.2	75
(ii)of Free acceleration	2.45	---	65
