The most visible change was the Automatic Headlamp On (AHO) standard, which aligned with BS4 and addressed safety concerns under the new emission norms.<\/span><\/p>\n<h2><b>What is BS6 (BSVI)?\u00a0<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The sixth generation of the emission standard, referred to as BS6, offers an important advance over the previous BS4 emission standard in terms of reducing air pollution.

Additionally, BS6 limits particulate matter (PM) to a mere 4.5 mg\/km for petrol vehicles.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Stricter Diesel Limits:<\/b><span style=\"font-weight: 400;\"> BS6 drastically cuts diesel emissions. While BS4 allows 250 mg\/km of PM, BS6 restricts it to 80 mg\/km. BS6 also reduces combined hydrocarbon (HC) and NOx limits for petrol from 300 mg\/km to 170 mg\/km.<\/span><\/li>\n<\/ul>\n<h3><b>Differences Between BS4 and BS6 &#8211; Pollution Emission Norms\u00a0<\/b><\/h3>\n<table>\n<tbody>\n<tr>\n<td><b>Fuel Type<\/b><\/td>\n<td><b>Gases release<\/b><\/td>\n<td><b>BS4<\/b><\/td>\n<td><b>BS6<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Diesel<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Nitrogen Oxide<\/span><\/td>\n<td><span style=\"font-weight: 400;\">250 mg\u00a0<\/span><\/td>\n<td><span style=\"font-weight: 400;\">80 mg<\/span><\/td>\n<\/tr>\n<tr>\n<td><\/td>\n<td><span style=\"font-weight: 400;\">Hydrogen Carbons and Nitrogen Oxide<\/span><\/td>\n<td><span style=\"font-weight: 400;\">300 mg\/km<\/span><\/td>\n<td><span style=\"font-weight: 400;\">170 mg\/km<\/span><\/td>\n<\/tr>\n<tr>\n<td><\/td>\n<td><span style=\"font-weight: 400;\">Particulate Matter<\/span><\/td>\n<td><span style=\"font-weight: 400;\">25 mg<\/span><\/td>\n<td><span style=\"font-weight: 400;\">4.5 mg\/km<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Petrol<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Nitrogen Oxide<\/span><\/td>\n<td><span style=\"font-weight: 400;\">80 mg<\/span><\/td>\n<td><span style=\"font-weight: 400;\">60 mg<\/span><\/td>\n<\/tr>\n<tr>\n<td><\/td>\n<td><span style=\"font-weight: 400;\">Particulate Matter<\/span><\/td>\n<td><span style=\"font-weight: 400;\">&#8211;<\/span><\/td>\n<td><span style=\"font-weight: 400;\">4.5 mg\/km<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3><b>BS6 Slashes Pollutant Limits<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Compared to BS4, BS6 regulations significantly tighten restrictions on vehicle emissions. <\/span><a href=\"https:\/\/www.olx.in\/cars_c84?filter=petrol_eq_diesel\"><span style=\"font-weight: 400;\">Diesel car<\/span><\/a><span style=\"font-weight: 400;\"> emissions are drastically reduced, with BS6 allowing only 80 mg\/km compared to the much higher 250 mg\/km permitted under BS4.

The fuel&#8217;s hardly noticeable changes to its chemical composition are the cause. The simple response is that automobiles with BS6 engines won&#8217;t be distributed after April 2020. The manufacturers are being requested to cease producing BS6 vehicles, as it relates to them. Never forget that improper and incomplete combustion results in a changed fuel flow pattern, which increases the emission level.
