Bharat Stage 6 Norms

Published by revjust21 on

Bharat stage 6

s stated in the previous article, Bharat Stage refers to emission norms of automobiles in India. Bharat Stage 6 Norms are going to be fully applicable in India from 2020 April. Now let us have the look at what these norms are and how these are different from Bharat Stage 4 Norms.

Bharat Stage 6 Emission Norms for Diesel vehicles.

The BS-VI Norms for Diesel vehicles are for majorly Particulate Matter and Nitrogen Oxides / Nitrox (NOX). Emission limits are defined as the amount of pollutant to be emitted per distance of run (gram per kilometer /g/km) or amount of pollutant emitted per unit of specific fuel consumption (g/kWh).

Bharat Stage 6 Norms
Bharat Stage 6 Emission Norms Diesel M1, M2, N1 Class I Vehicles (G Weight < 3500 kg).
Bharat Stage 6 Norms
Bharat Stage 6 Emission Norms for Diesel N1 Class II Vehicles (G Weight < 3500 kg).
Bharat Stage 6 Norms
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel N1 Class III, N2 Vehicles (G Weight < 3500 kg).
Bharat Stage 6 Norms
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel Two Wheeler Vehicles (G Weight < 3500 kg).
Bharat Stage 6 Norms
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel Three Wheeler Vehicles (G Weight < 3500 kg).
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel M, N Transient cycle Vehicles (G Weight > 3500 kg).
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel M, N Transient cycle Vehicles (G Weight > 3500 kg).
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel M, N Steady cycle Vehicles (G Weight > 3500 kg).
Emission Norms comparison between BS-IV and BS-VI Norms for Diesel M, N Steady cycle Vehicles (G Weight > 3500 kg).

Vehicle categories

M1: 4 wheeler Vehicle for passengers, with a maximum of 8 seats in addition to the driver seat.

M2:4 wheeler Vehicle for passengers, with more than 8 seats in addition to the driver seat.

M3: 4 wheeler Vehicle for passengers, with more than 8 seats in addition to the driver seat and mass exceeding 5 tonnes.

N1: 4 wheeler Vehicle for goods carriage with mass not exceeding 3.5 tonnes.

 N2: 4 wheeler Vehicle for goods carriage with mass not less than 3.5 tonnes but not exceeding 12 tonnes.

N3: 4 wheeler Vehicle for goods carriage with a mass exceeding 12 tonnes.

In Bharat Stage 6 / BS-VI Norms the independent limit of Nitrox (NOX) is not defined for three-wheelers. So the limit shown here is Hydrocarbon and Nitrox (HC + NOX).

Emission Norms for Petrol engines

Now, Bharat Stage 6 / BS-VI Norms for petrol engines majorly focus on pollutants like Hydro Carbons, Carbon Monoxide, Nitrox, Nitrox, and Hydro Carbons Combined.
