Bharat Stage (BS) emission norms are standards instituted by the government to regulate output of air pollutants from motor vehicles. "Up to March 31, 2020, we can sell it (BS4 vehicles). We should be given one more months' time," the lawyer said, adding, "There is slowdown in the automobile industry.
In a recent ruling, The Supreme Court has ruled that BS4 vehicles will not be sold after March of 2020 when the BS6 norms are put in place. The BS (Bharat Stage) norms are based on EURO (European) emissions standards. It wasn't until BS4 (4th stage) (BS IV), that more stringent emissions mandates were enforced.
The engine won't change because of Bs4 or bs6. The fuel injection will improve smoothness in case of bikes like bullet. BS6 will pollute less. Bs4 will be cheaper to buy.
If you have already purchased a BS4 Bikes before April 2020 then you need not worry it will remain valid till its end of life. So, if you are planning to buy Bajaj Bikes at Noida/Ghaziabad.
BS4 vehicle require larger catalytic converters in terms of flow volumes to eliminate harmful nitrogen based gasses. To retrofit petrol powered cars as most of them already have an on board diagnostics (OBD) 2 port, which controls engine behavior in real time.
The straight answer is YES!! a BS4 vehicle can run on new BS6 fuel provided it is a petrol engine and need to worry about any problems.
The new fuel will have significantly lower sulphur content which is responsible for CO, HC and NOx emissions. The switch to BS6 from BS4 and skipping BS5 entirely in a little over three years is an unprecedented move on a global scale.
The BS6 fuel has sulphur content equal to 10mg/kg while the BS4 grade fuel has sulphur content equal to 50mg/kg. Lesser sulphur content automatically means greener and cleaner fuel quality as it reduces the emission of harmful pollutants like carbon monoxide, nitrogen oxides and hydrocarbons.
AHO was made mandatory as it can avoid accidents in low light and rough weather conditions. It also helps motorcyclists to be more visible on the road. Most Indian bikes lack DRL. So it's better to have the headlight on at all times for the safety of motorcyclists.
Many manufacturers after 1 April are only making BS4 (Honda for one). The VIN can give you the date of manufacture. If manufactured after 31 March then a BS3 car cannot be registered in a BS4 city. There is a grace period (6 months?) in which BS3 cars manufactured before 1 April can still be registered.
The Hon'ble Supreme Court in its order on October 24th, 2018 had declared that no vehicles that comply with Bharat Stage-IV can be sold or registered after March 31st, 2020, thereby giving enough time to the automobile manufacturers' to plan their inventories.
As per the mandate ruled out by the Supreme Court of India in October 2018, the sale and purchase of Bharat Stage IV vehicles will be banned after April 2020. The court has asked all car manufacturers to clear their stock of BS4 vehicles before the deadline.
BS4 vehicles can be used till registration period: In the light of upcoming BS6 emission norms in April 2020, the government is addressing some of the concerns regarding current BS4 compliant vehicles. As per the announcement, these vehicles will be allowed to run as long as their current registration period allows.
There is a lot of confusion around car buying till April 2020 when India will adopt BS6 regulations. A big difference between the current BS4 and upcoming BS6 fuel will be that the new BS6 fuel will contain 5 times lesser sulphur traces (10 parts per million) compared to BS4 (50 parts per million).
