How Does EGR Impact Horsepower in Vehicles?

Discover how EGR (Exhaust Gas Recirculation) affects vehicle horsepower and engine performance.

18 views

Yes, EGR (Exhaust Gas Recirculation) can reduce horsepower. By recirculating a portion of the exhaust gases back into the intake air, EGR lowers combustion temperatures and reduces nitrogen oxide emissions. However, this also results in a slight reduction in engine performance and horsepower since the combustion process becomes less efficient.

FAQs & Answers

  1. What is EGR and how does it work? EGR (Exhaust Gas Recirculation) works by recirculating a portion of exhaust gases back into the engine's intake to lower combustion temperatures.
  2. Can EGR systems harm engine performance? Yes, while EGR helps reduce emissions, it can slightly decrease horsepower due to less efficient combustion.
  3. What are the benefits of using an EGR system? EGR systems help lower nitrogen oxide emissions and improve overall air quality, making them beneficial for the environment.
