Next-gen EcoBoost Engines Promise More Power and Better Fuel Economy

Cooled EGR (exhaust gas recirculation) as applied to an EcoBoost engine can improve efficiency and reduce the tendency for an engine to knock. Cooled EGR is exhaust gas that is cooled in a heat exchanger before being pumped back into the cylinders, where it lowers the combustion temperature.

The result: a cleaner-running engine that develops more power and delivers as much as a 5 percent gain in fuel economy over today’s already efficient EcoBoost engines. Ford’s current generation of 2.0-liter EcoBoost I-4 and 3.5-liter EcoBoost V-6 engines deliver between 10 and 20 percent better fuel economy than comparable normally aspirated V-6 and V-8 engines, respectively
