Tell me the the difference between BS4 and BS6 compliance engine

Question

Accepted Answer

BS4 and BS6 compliance engines differ in terms of emission standards and technological advancements.

BS4 engines comply with Bharat Stage 4 emission norms, while BS6 engines comply with Bharat Stage 6 norms.
BS6 engines have stricter emission standards, resulting in lower levels of pollutants being released into the environment.
BS6 engines require the use of advanced technologies such as selective catalytic reduction (SCR) and diesel particulate filters (DPF) to meet the stringent norms.
BS6 engines are more fuel-efficient and produce lower levels of harmful emissions like nitrogen oxides (NOx), particulate matter (PM), and carbon monoxide (CO).
BS6 engines may require the use of higher quality fuel with lower sulfur content.
BS6 compliance also involves improvements in engine design, combustion efficiency, and exhaust after-treatment systems.
