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 Fiesta becomes UK all-time best seller

We may regard Ford as an American automaker, but ask a Brit and they may tell you otherwise. The Blue Oval has, after all, been selling cars in the UK since 1903, and started manufacturing there as far back as 1911 when it began local production of the Model T in Manchester. Last year Ford ended 100 years of vehicle manufacturing in the UK when the last Transit van rolled off the assembly line in Southampton, but it's still the biggest-selling automotive marque in Britain.
Ford has led the British market for 34 out of the past 45 years, selling more Fiestas than any other company sells any other car in the UK since 2009... when it overtook the Focus. In fact the Fiesta has now become the best-selling car in British history, topping 4,115,000 units since its introduction in 1976. The previous record was held by - you guessed it - another Ford: the Escort sold 4,105,961 units over the course of its 32 years on the British market.
Although the Fiesta is no longer manufactured in the UK (previous versions having been built at Dagenham until 2002), engines are: the EcoBoost line was developed at the company's R&D center in Essex and are built at the factory in Dunton, while its diesel engines were developed at Dagenham in East London. Even the 1.6-liter EcoBoost engine in the Fiesta ST is built in South Wales.

Ford Fiesta ST gets worked out on the track

We're big fans of the turbocharged Ford Focus ST, and we're plenty excited that the Blue Oval will be offering a similar treatment on the smaller Fiesta here in the United States, too. We first saw the production-ready Fiesta ST five-door at the Los Angeles Auto Show last fall, and Ford has now released this video of a Euro-spec three-door ST being flung around the track.
But not just any track - the challenging Track 7 of Ford's Lommel Proving Grounds in Belgium. The course features 20 turns and plenty of elevation changes along its 2.7-mile loop, and David Put, a vehicle dynamic specialist at Ford, shows just how good the pint-sized Fiesta ST is at handling the lot, even getting the smallest ST up on three wheels every now and then.
It sure does look like a lot of fun, and makes us really eager for our chance to try this ourselves. Scroll down to see the hot little Ford getting busy.
