Difference between Bs4 and Bs6

Question

Accepted Answer

BS4 and BS6 are emission norms set by the government to regulate the amount of pollutants emitted by vehicles.

BS4 stands for Bharat Stage 4 and BS6 stands for Bharat Stage 6.
BS6 is the latest emission standard set by the government, which is more stringent than BS4.
BS6 compliant vehicles emit lower levels of pollutants such as nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter compared to BS4 vehicles.
BS6 compliant vehicles also have advanced technologies such as selective catalytic reduction (SCR) and diesel particulate filter (DPF) to reduce emissions.
BS6 compliant vehicles are required to use BS6 fuel, which has lower sulfur content compared to BS4 fuel.
