Ford to Introduce Cooled EGR in Next-Gen EcoBoost Engines

In brief: Ford's next-generation of EcoBoost turbocharged, direct-injection gasoline engines will introduce cooled exhaust gas recirculation (EGR), improving fuel economy up to 5%.

The word

Ford made the announcement for the cooled EGR EcoBoost engines at the 2010 SAE World Congress in Detroit. Cooled EGR has several benefits to gasoline direct-injection engines including improved efficiency, reduced particulate matter (PM) emissions, and reduced engine knock tendency.

The fuel efficiency gains would be about 5% over current EcoBoost engines and Ford is exploring other options to improve that efficiency further, such as more advanced turbocharging.

Gasoline direct injection (GDI) engines often suffer from increased PM emissions due to the way liquid gas often enters the combustion chamber. EGR can sidestep that issue by reducing combustion temperatures which eliminates the need for heavy enrichment.

And so ...

Ford is also introducing a similar system for flex-fuel and ethanol-fueled engines.
