What is the difference between BS4 and BS6 Engine?
Many of you will know about BS4 Engine, but do you know what BS6 Engine is? What is the difference between these two? What are the new things in BS6 Engine which is not present in the current BS4 Engine?
If you want to get complete information about it, then you will have to read my article Difference between BS4 and BS6 Engine in Hindi.
You must be thinking that right now the Government of India has adopted BS4 and why BS6 right now. So let me tell you a few days ago our Road and Transport Minister has told about the implementation of BS6 by 2020. But sources have revealed that the Honda Activa 125, the first two-wheeler with BS6 Engine, has been launched recently.
At the same time Bharat Stage 4 (BS4) emission norm is applicable in India and it will take a long time to change it. The main plan was to bring Bharat Stage 5 (BS5) engine by 2019 so that up to 80% of Particulate Matter (such things that can cause us lung diseases) could be prevented. And there was a plan to bring BS6 engines by 2024.
But as the pollution level increased day by day, that is why the government is thinking of abandoning the BS5 engine plan and adopting BS6 Engine. So that pollution can be prevented to a great extent. So without delay, let us know what is this BS4 and BS6 Engine? What is the difference between these two? And why the government wants to adopt it very quickly in full detail.
Bharat Stage Emission Standards were introduced in 2000, these are the emission standards set up by the central government to control the pollutants emanating from the engines.
There are many different types of norms that have been implemented over time by the Central Pollution Control Board which comes under the Ministry of Environment and Forest and Climate Change.
Bharat Stage Norms are based on european regulations. And BS4 norms have been implemented in our country from April 2017.
What is Bharat Emmission Standards?
According to the Euro Norms adopted by Bharat Stage, there should be a maximum limit to leave pollutant for all vehicles. Pollutant such as CO2, nitrogen oxide, sulphur and suspended particulate matter.
If a vehicle abandons its pollutant more than its specified limit, it cannot be sold in Europe.
In our country, we follow Euro Norms as Bharat Stage Norms. Which we are slowly implimenting in all the cities of our country.
Difference in BS-IV and BS-VI standards
If we compare both of them with Bharat Stage Standards, then we will know the difference between these two.

Petrol Emission Norms (All figures in g / km)
Emission Norm CO HC NOx HC + NOx PM
BS-III 2.30 0.20 0.15 - -
BS-IV 1.00 0.10 0.08 - -
Euro 6 1.00 0.10 0.06 - 0.005
Diesel Emission Norms (All figures in g / km)
Emission Norm CO HC NOx HC + NOx PM
BS-III 0.64 - 0.50 0.56 0.05
BS-IV 0.50 - 0.25 0.30 0.025
Euro 6 0.50 - 0.06 0.17 0.005
CO emission or carbon monoxide emission is mainly found in petrol engines. And due to exposure to them for a long time, oxygen transfer can also be reduced, which can also cause headache and nausea.
HC emission or Hydrocarbon is mainly found in petrol engines. And coming in contact with them for a short time can also cause headache, vomiting and disorientation.
