Be it diesel or petrol both have a considerable difference. Well, everything comes with some drawbacks or the other. Surely affect automobile manufacturers in India.

BS6 going live on 1st April 2020. What’s next?

The new cleanest emission norms are about to roll out. The decision of implementing the new norms was sooner than thought. BS4 emission norms were launched after nearly a decade. Whereas BS6 norms just after three years from the launch of BS4. Will the next emission norms be new Bharat Stage or will the government completely ban the internal combustion engine?

BS6 Era: Boon to economy or Bane to Performance!?!

From the first emission norms that were India 2000 till BS4 each and every emission norm require a pollution certificate. Well, the new BS6 emission norms are no different they too need to be checked regularly for exhaust emission.

What is SCR and AdBlue in BS6 Diesel Engines and was it necessary?

In the new cleaner BS6 emission norms, the internal combustion engines are it petrol or diesel have seen some upgrade. Later having the most number of upgrades. This is because the diesel engine’s exhaust emission is higher than the other counterpart. To reduce those emissions SCR or Selective catalytic reduction system is installed in the exhaust of only the Diesel engines.
