SAE 2010: Next-gen Ford EcoBoost engines to get even more efficient with cooled EGR
Filed under: Technology, Ford
Over the course of 2010, Ford plans to aggressively ramp up its EcoBoost engine strategy with two new four-cylinder engines and the first rear-wheel-drive application of the boosted 3.5-liter V6. However, this is just the beginning as Ford is already hard at work on the next generation of EcoBoost engines. At the SAE World Congress on Wednesday, Dan Kapp, director of powertrain research and advanced engineering, and Bob Fascetti, director of large gas and diesel engine engineering, will be announcing that the next generation EcoBoost engines are adding cooled exhaust gas recirculation (EGR) systems.
Just like the direct injection and turbocharging used on the current EcoBoost mills, cooled EGR is derived from diesel engines. Exhaust gas is routed back into the combustion chamber to reduce the combustion temperatures. Controlling the combustion temperature has a number of benefits, primarily allowing the use of a leaner air/fuel mixture, which would normally burn hotter and thus produce more nitrogen oxide emissions. Running the exhaust gas through a heat exchanger before sending it into the intake stream improves the cooling effect further.
Using cooled EGR will also allow the use of even higher compression ratios without getting into knock situations. Engineers will be able to downsize engines even further without sacrificing power and torque. Overall, Ford estimates cooled EGR will improve EcoBoost efficiency by an additional five percent, further closing the gap between gasoline and diesel. More power, less fuel - it's a win/win scenario.
