The changes in the emission norms from BS4 to BS6 are huge. The numeric value for the harmful gasses from the exhaust has drastically come down. This is lead every automobile manufacturer in India to work their heel and toe in achieving the new BS6 norms.
The change led to many questions arising in the consumer’s head. Let’s see one of such questions.
What will happen to BS4 vehicles after 2020?
BS4 Vehicles | Fairly Non-polluting
BS4 implemented after 7 years in April 2017, started the journey of fairly less polluting vehicles. Many small changes in the vehicles were made to make them BS4 compliant. The changes include.
- Open-loop ECU became closed-loop ECU in two-wheelers.
- The catalytic converters became more efficient in breaking down pollution.
There were no extra noticeable changes when coming from BS3 to BS4.
BS6 Vehicles | Even less, Non-Polluting
The growing pollution forced the Indian government to skip a ladder in between and jump straight to BS6. The new norms have dropped the polluting substances from the exhaust by a considerable large amount. For instance.
- Sulphur oxides (SOx) are reduced by 5-times than before.
- There is a 25% reduction of NOx (Nitrogen Oxides) in petrol engines and a nearly 70% reduction in diesel.
