Reduce Harmful NOx Emissions\u003c\/strong\u003e\n\u003cp\u003e\u003cbr\u003eThe main goal of the EGR system is to cut down nitrogen oxide (NOx) — a major air pollutant that contributes to smog and acid rain.\u003cbr\u003eBy routing a small amount of exhaust gas back into the intake, the EGR valve lowers the combustion temperature, which prevents NOx from forming.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2. Lower Combustion Temperature\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eExhaust gases don’t contain oxygen, so mixing them with fresh air\/fuel makes the mixture less oxygen-rich.\u003cbr\u003eThis causes combustion to happen at a lower temperature, reducing thermal stress on engine components and keeping the engine cooler.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.
