EGR Systems

EGR (Exhaust Gas Recirculation) valves can lead to several disadvantages, including reduced engine performance due to the introduction of exhaust gases into the intake, which can dilute the air-fuel mixture. They may also contribute to increased carbon buildup in the intake manifold and on the valves, potentially leading to maintenance issues. Additionally, EGR systems can complicate engine design and tuning, potentially resulting in higher emissions if not functioning properly. Lastly, in some cases, they can cause overheating or lead to engine knocking if the recirculated gases are not effectively managed.
