Curious about how your vehicle’s EGR (Exhaust Gas Recirculation) valve impacts fuel efficiency? This comprehensive guide explores the relationship between EGR valve function and fuel consumption, helping you understand its importance for both engine performance and fuel economy.
📌 Quick Answer:
Yes, the EGR valve significantly affects fuel consumption. A properly functioning EGR valve can improve fuel efficiency by 5-10%, while a faulty one can decrease fuel economy by up to 20%.The valve works by recirculating exhaust gases back into the combustion chamber, reducing engine temperature and improving overall efficiency.
