What is BS4 & BS6?
Heard about BS4 & BS6,What is BS4 & BS6?
Currently indian launching cars are in BS4.But in 2020 almost all automotive companies produce BS6 Engines.Kia Seltos currently running in BS6 Engine.
The auto industry is set to transition to the BS6 regime in April 2020, in keeping with the Supreme Court’s diktat. This is not the first time that manufacturers have had to reconfigure their engines to meet emission control norms. The Bharat Stage (BS) norms, which are based on European emission standards, were initially rolled out in 2000. Subsequent iterations, BS2 and BS3, came into effect in 2001 and 2005 respectively.
However, it wasn’t until BS4 was implemented that emission levels were capped at levels comparable to global standards.
In 2016, the government decided to skip BS5 in favour of devising a more stringent standard to check rising pollution from vehicular exhausts. After much deliberation and extensions, it was decided that the final deadline for the implementation of BS6 norms would be April 2020. How is BS6 different from BS4?
One of the major differences between BS6 and the incumbent BS4 is that the former contains five times lesser suplhur content (10 parts per million) as compared to BS4 (50 ppm). Oxides of nitrogen (NOx), produced as a result of combustion, will be brought down by 70 per cent for diesel, and 25 per cent for petrol engines. Another significant change will be the presence of OBD (Onboard Diagnostics) and RDE (Real Driving Emission) on all vehicles, enabling real-time tracking of emissions.
With BS6 fuel already available in many cities, owners of older generation cars can opt for it at filling stations. This can produce mixed results. There is a direct correlation between a fuel’s suplhur content and its emission level – lower sulphur content translates into cleaner combustion. Petrol, which has lower sulphur content, emits less carbon monoxide, NOx and other toxic hydrocarbons. BS6 diesels will release less particulate matter (PM) upon combustion.
Users of petrol cars have little to worry about compliance as there is very little difference between BS4 and BS6 fuels. However, the same isn’t the case with diesel vehicles. The older generation BS4 diesel has five times the sulphur content (50ppm) as compared to BS6 (10ppm)
A diesel engine employs an injector to ionize fuel for combustion. Sulphur acts as a lubricant for diesel injectors. The use of BS6 diesel in older generation BS4 cars will cause the injector to wear out prematurely as low sulphur in the fuel will lead to less lubrication.
