Bharat stage and Bharat standard?

Bharat Standard

(Estd in 2008 by Govt. Of India)

Bharat Stage (Included, BS-III BS-IV, BS-VI)
Introduction
Bharat standard(BS) is equivalent to EURO Standards basically there are emission standards started by GOVERNMENT OF INDIA (GOI) in 2000 on the recommendation of R.A.Mashelakar committee to regulate air pollution which are output or emissions of only motor vehicles so it also include petroleum, refinery.

What is need of BHARAT STANDARD (BS)

The need of BHARAT STANDARD is arises as the number of population increases the need motor vehicle is also increase and the need of vehicles leads to increased the contamination of air quality by the various types of exhaust gases emitted from the vehicle like

( CO, CO2, Sulphur, Benzene, SOx (Mainly), lead oxide (highly toxic).

Petrol emission:- CO, CO2, SOx, NOx, soot, benzene, lead oxide.

Diesel emissions-SOx(emitted in large amount), NOx, CO, CO2, Soot , benzen

Implementation of BHARAT STANDARD (BS)

From April 1, 2017 BS-IV implemented in the whole country (pan India) & go decided to implement BS-VI from April 2020 onwards by skipping BS -V

But in Delhi ( Capital of India) BS-VI is implemented on April 1, 2018.

According to Bharat Standard (in PPM)

Sulphur emissions (in part per million) as per Bharat Stage

                   PETROL           DIESEL

BS-III.          150                       350

BS-IV.            50                         50

BS-VI.            10                         10

you should understand what is PPM ?

Part per million is the Full form of PPM but we are going ot understand the meaning of ppm that is meant for one particle in one million particles is emitted or exhausted from the vehicle exhaust pipe .

In India we follow American standard so we adopted ppm system or ppm unit.

Basically PPM is a unit to measure physical quantities like Sulphur content, Air Quality, particulate matter like PM2.5, PM10 is also estimated by PPM.

Here we need to reduce the sulphur content because sulfer is the primary pollutant.

BS-VI is basically adopted to reduce the sulphur content in exhaust emitted from the motor vehicles.

Benefits of BS-VI

In BS-VI Carbon monoxide is reduced by 30% and NOx is also reduced by 80% and BS-VI also put a limit on Particulate matter (PM) and hydrocarbon which are not included in any earlier norms of emission.

We know that refinery also regulated by Bharat Standard hence the Quality of fuel will also improve in BS-VI.

In BS-VI the fuel is much clears than BS-IV.

We should adopt

Some problems need  to overcome as the we know the India is a big country so implementation of BS-VI Is difficult task because here different class exist so BS-VI technology need to be cheap and easily available in all location Including remote locations of Indian territory.

Thanks to the reader i hope this information given by me will clears and fulfill the reader all doubt  regarding BS-III, BS -IV and BS-VI
