Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

Ford 1.0L takes third-straight International Engine of the Year award

Ford's 1.0-liter EcoBoost is proving to be The Little Engine That Could, and it continues to acquit itself well, finding favor as one of the best powerplants in the world. To confirm it yet again, the tiny mill just won the International Engine of the Year award for the third year in a row, likewise also nabbing the title in the Sub 1.0-liter category.
Packing 123 horsepower and 148 pound-feet of torque with overboost (125 lb-ft normally), the tiny engine combines impressive power in a size small enough to be a carry-on item for a commercial flight. US buyers only got a taste of the award winner in the 2014 Fiesta, while the 1.0 EcoBoost has been available throughout the Ford lineup in Europe for a few years now. American sales have reportedly been strong, however, and next up in the US, the mill will find its way into the 2015 Focus.
The panel of 82 jury members from 34 countries also named the Mercedes-AMG 2.0-liter turbo found in the A45, CLA45 and GLA45 AMG models with 355 hp and 332 lb-ft as the best New Engine for 2014. The electric powertrain from Tesla won Green Engine prize, and the 4.5-liter V8 from the Ferrari 458 Italia took home the honor of top Performance Engine yet again. You can check out all the winners below, and scroll down further to read Ford's celebratory announcement of its award.
