Indian Automotive Industry Revolution - April 2020

Hello Everyone,
A government of India has taken an initiative towards the green environment and reduce CO2 percentage the new Pollution Norm is made compulsory.

What will be the changes After Implementing BS6?

  • BS-VI will definitely be going to bring a drastic change in the automotive market in India.
  • We will get more fuel efficient and very low emission producing vehicles in near future. Downsizing and down speeding will yield smaller and powerful engines. Diesel vehicles will get more expensive as they required more after treatment to stay clean. This will attract OEMs towards alternative fuels and hybrid technologies.
  • Indian driving speeds are less than European driving speeds, hence it is difficult to achieve temperature which is necessary to operate particulate filter. Hence domestic tire-I and tire-II suppliers have great opportunity to innovate new engine technology and emission control technology suitable to Indian driving conditions.Through all these efforts people can ensure significant reduction in air pollution from automobiles. This will bring remarkable improvement in air quality in highly populated cities as automobiles are main source of air pollution in cities.
  • To achieve emission limits specified in BS-VI ample amount of engine electronics will required. This will enhance business of domestic and MNC automotive electronic suppliers. Vendors and engineering solution providing companies for Eco testing, fuel system testing and emission testing are also going to benefit a lot.

What will be the norms and percentage of pollutants?

Petrol Engine Emissions:

  • HC - NO change 
  • NOx - 25% Reduction than existing

Diesel Engine Emissions:

  • HC + NOx - 43% reduction in BS6
  • NOx - 68% reduction
  • PM - 5 Fold reduction.

What will come into effect from April 2020?

1. Bharat Stage 6 Norms will take into Effect.
2. It is the most advanced emission standards for automobiles and it is equivalent to Euro-VI norms.
3. In order to reduce Vehicular Pollution, the government decided to close leapfrog from BS-IV to BS-VI.
4. The new norms make onboard diagnostics Mandatory for all Vehicles.
5. The OBD unit can identify likely areas of malfunction by means of default codes stored on a computer.
6. Two wheelers, manufacturers will introduce Fuel Injection system - First time in India.

What will be changed in Powertrain?

1. In CRDI Engine it will be with Variable Geometry Turbocharger.
2. Highly Complicated engines with advance Variable Geometry Turbocharger and Sensors.
3. EGR (Exhaust Gas Recirculation ) + SCR ( Selective Catalytic Reduction ) both will be compulsory.
4. For Nitrogen Oxide NOX Control: SCR( Selective Catalytic Reduction ) System (Closed Loop) has to be used.
5. PM ( Particulate Matter ) Control: DOC ( Diesel Oxidation Catalyst ) + DPF ( Diesel Particulate Filter) will be used.
6. Ammonia slip catalyst.
7. Three-way Catalyst.


1. Diesel Oxidation Catalyst (DOC): 
  • Formation of NO2 for CRT effect in DPF.
  • Catalytic Combustion of Hydrocarbons for regeneration.
2. Diesel Particulate Filter (DPF):
  • Separation of sooth and Ash.
3. Hydrolysis Catalytic Converter:
  • Evaporation of AdBlue.
  • Mixing with Exhaust Gas.
  • Conversion of AdBlue into Ammonia NH3 and CO2

What will be the changes in Prices and Maintenance?

Vehicle Price: Approx. Rs 25 Lacs EMI: Increase by 15K-18K per month

Vehicle Maintenance: Uncertain: Only can be maintained at High-end Company Workshops, Lot of sensors, Electronic engines, multiple filters, etc.
