Overview
From 1st April onwards BS6 Phase-2 emission standard has been implemented in India i.e. from 1st April onwards all vehicles will have to follow this standard. It is the next phase of BS6 emission norms but what will it change? Under this, now real time testing of cars will be done while the cars are running and the data will be recorded whether the pollution is not exceeding the prescribed limit. Now the vehicles which are coming will also have to get RDE certification. Portable emission measurement system will be given in all cars.
Today we will know what is BS6 Phase 2 RDE norms, what are its benefits, will it apply to old vehicles as well. And what about diesel vehicles?
HIGHLIGHTS:-
- What is BS6 Phase 2 in 2023 ?
- Difference between BS6 Phase-2 and BS6
- Why Diesel Cars Discontinued
- No impact on Big Diesel Cars
In such a situation, it is important to know what is the RDE norms and what will be its effect now. Also, will any changes have to be made in your old car due to this. Let us know what are these new changes…
What is RDE norms ?
In simple language, all the time monitoring of the pollution caused by the car is called RDE. For this, onboard self-diagnostic devices are installed in cars. Under BS 6 Phase 2, the biggest change has been done in RDE. For this, two devices have been installed in the cars, which will monitor the data of pollution caused by the car at all times. Due to this, the price of cars has also increased.
This standard will not change the driving or riding experience of the vehicle but its real effect will be seen inside the engine of the vehicle. It will be fitted as standard in vehicles whose engines did not have OBD (On Board Diagnostic).
This rule applies to all vehicles whether it is a car or a bike. But what will this OBD do? Actually OBD will work to monitor real-time driving emission level. Along with this, the main equipment of this process will also be monitored.
Catalytic converter and oxygen are the main equipment in this. If any of these parameters go above the prescribed standard, it would indicate that the vehicle needs to be serviced or checked. In such a situation, it will work to keep the emission level within limits.
Main difference between BS6 Phase-2 and BS6
The main difference between BS6 Phase-2 and BS6 will be that earlier the emission level of vehicles was tested in the lab, but now every vehicle will have its own monitoring system which will work to monitor the vehicle in real-time.
Why Diesel Cars discontinued ?
After the new rules, companies discontinued diesel engines with a capacity of less than 1.5 liters. The reason for this was that it would have cost a lot due to the change in these engines, due to which the companies had to increase the price of the cars significantly. So selling any small car at that price would have been very difficult. Due to this, companies discontinued cars like Hyundai i20, Verna, Amaze Diesel, City Diesel.
No Impact on Big Diesel Cars
According to new concerns the differences will not make much difference on larger engines. Engines over 2.0 liters were already doomed with the new technology. Because of this, not much has been changed in them. Due to which there is not much burden on the Auto Manufacturing Authority.
The emission standards first came into force in the year 2000
Bharat Stage was first implemented in India in the year 2000. Earlier, there was no standard set regarding carbon emissions in India. BS was implemented in India on the lines of Euro, the European carbon emission standard. At present, the BS4 carbon emission standard is applicable across the country. However, in April 2020, the next emission standard BS6 came into force. The Government of India has implemented BS6 directly after BS4 leaving one stage. The reason behind doing this has been given to reduce the level of pollution caused by vehicles.
Reduce Sulfur Emissions
Each emission standard seeks to reduce the amount of sulfur in the exhaust gases from petrol and diesel vehicles. Under the BS3 standard, petrol vehicles could emit 150 mg per kg of sulphur. Which has reduced to 10 mg per kg in BS6. Similarly, diesel vehicles could emit 350 mg per kg of sulfur under BS3 standard norms, which has come down to 10 mg per kg.
| Sulfur Emissions | BS3 (mg/kg) | BS4 (mg/kg) | BS6 (mg/kg) |
| Petrol | 150 | 50 | 10 |
| Diesel | 350 | NA | 10 |
Let us tell you that due to BS6 Phase-2, Hyundai i20 Diesel, Tata Altroz Diesel, Skoda Superb, Octavia, Renault Kwid, Maruti Alto 800, Toyota Innova Crysta Petrol, Nissan Kicks, Honda City 4th Generation are being discontinued.
