An EGR valve, or exhaust fuel recirculation valve, is a tool that helps cut back emissions from diesel engines. It does this by recirculating a portion of the exhaust fuel again into the engine’s consumption. This helps to decrease the combustion temperature, which in flip reduces the formation of nitrogen oxides (NOx). NOx is a serious contributor to smog and acid rain.
EGR valves can grow to be clogged over time with soot and different deposits. This could cut back their effectiveness and result in elevated emissions. Cleansing the EGR valve is a comparatively easy and cheap manner to enhance its efficiency and cut back emissions.
