BSIV vs BSVI

Everyone is talking about shifting to BSVI from BSIV. So, in today’s blog we will try to entail the topic and compare both the models in terms of performance and efficiency. We will also discuss BSIV vs BSVI, which one is better. Before discussing about BSVI compliant engine or BSVI emission, first we shall discuss about the exiting BSIV engine, performance, norms, and its significance.

BSIV vs BSVI

BSES (Bharat Stage Emission Standards) is the governing organization for all types of vehicle emission in India, unveiled the first emission norms named “India 2000”. The introduction was made in the year 2000. Moreover, BSII and BSIII were introduced in 2005 and 2010 respectively. In 2017, BSES introduced BSIV with stricter norms and standards after a gap of seven years.

The government body set significant changes in terms of ignition control, electronic control units, and tailpipe emissions. The most significant addition was automatic headlamp on (AHO), which accommodated to safety aspect of new emission standards. Furthermore, the BSVI emission standard is the sixth iteration of these norms, and it is the substantial leap in pollution reduction as compared to BSIV. In order to achieve better emission norms, the BSV has been skipped.  

BSIV vs BSVI- How BSVI is Better

Both BSIV and BSVI have standards which are efficient in reducing pollution levels from car or two-wheeler emissions. BSVI emission standards are stricter as compared to BSIV and offer the manufacturers to utilize it in upgrading their vehicle safety standards. The most visible change came in form of stricter permissible emission norms.  

With rising concern regarding global warming and cleaner environment, central government has decided to fast-forward the pollution emission norms and jumped to BSVI instead of launching BSV. The BSVI standard was introduced in April 2020. Some of the differences (comparative analysis) between BSV and BS VI are listed below.

  • In BSIV, the nitrogen oxides emission limit is 80 mg/km while, in BSVI the limit has been reduced to 60mg/km. In BSVI emission regime, for petrol vehicles the PM (Particulate Matter) has been restricted to 4.5 mg/km.
  • A BSVI vehicle is required to use BSVI fuel only to achieve the desired emission levels as BSIV fuel will not be capable of adhering to the required emission norms due to higher levels. The Indian government has planned to dispense BSVI fuel in all the petrol pumps across India. The BSVI fuel can also be used in BSIV vehicles.  
  • As per BSIV standards, the norm for NOx from diesel vehicles is 250 mg/km, while in BSVI the limit has been reduced to 80 mg/km. The PM level has been reduced to 4.5 mg/km from 25mg/km, while the HC+NOc has been decreased 300mg/km to 170mg/km. Hence, a noteworthy pollution reduction can be seen in BSVI norms.
  • Several additional specifications have been introduced in BSVI which were not a part of BSIV. For instance, addition of Onboard Diagnostic (OD) which was not mandated in the emission norms set on BSIV. In BSVI, Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) are added which was not in BSIV norms. Additionally, in BSVI, in order to ensure the real-time measurement of emission from vehicles, Real Driving Emission (RDE) has been introduced.
  • Rather than emission norms, some standards are set for dispensed fuel also which improves the efficiency even better. In diesel and petrol, nitrogen and Sulphur play a crucial role. The BSVI fuel consists of five 10 ppm Sulphur content which is five times lesser than BSIV. Also, the permitted level for nitrogen oxide has been decreased by 25% and 70% in petrol and diesel engines respectively.

How Do BSVI Diesel Engines Work?

In BSVI engine, with the help of a catalyst, the selective catalytic reduction (SCR) unit converts NOx into water and diatomic nitrogen. The SCR units decrease the emission level of nitrogen oxide by using diesel exhaust fluid and AdBlue. The fluid contains to parts i.e. deionized water and urea. When emitted gases came in contact of fluid, the urea is converted into carbon dioxide and ammonia. This in turn, convert the nitrogen oxide into nitrogen and water vapor which results in minimized pollutants.

Currently, the AdBlue is being sold by limited distributers at a premium rate. However, the cost is anticipated to decline with a rapid increase in sale of BSVI diesel engines. The Indian government has mandated that after 1 April 2020, all the vehicles will be manufactured and sold should be equipped with BSVI compliant engines. Several manufacturers have launched BSVI cars and bikes in India.

Harmful Effects of Air Pollution Generated by Vehicle Emission

The pollution emitted from vehicles in India is measured by government agencies. They use the Air Quality Index (AQI) to gauge the level of pollution in a city. The AQI uses the below criteria to measure emission:

  • Carbon Monoxide (CO)
  • Nitrogen Oxide (NO2)
  • Ozone (OZ)
  • Particulate Matter (PM)
  • Sulfur Dioxide (SO2)

Higher pollution levels can also result in various health issues. Some of them are listed below:

  • Anaemia
  • Cancer
  • Itchy eyes
  • Kidney ailments
  • Lethargy
  • Lowered alertness
  • Respiratory and heart ailments
  • Throat and lung infections, asthma

Also, higher pollution level can impact the environment. Some of the major pollution impacts on environment are:

  • Acid rain and smog
  • Contamination of air, soil and water
  • Exhaustion of fossil fuel, the source for petrol and diesel
  • Global warming
