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 recalling 390,000 cars over door latch woes

Ford is recalling certain Fiesta, Fusion and Lincoln MKZ vehicles due to faulty door latches, marking the latest in what seems to be a recurring issue for the Blue Oval. This is the third door latch recall from Ford in 2015, following a 213,000-unit recall in March and a 205,000-unit recall in January. This one, however, is significantly larger. A total of 390,000 units are affected, including Fusions and MKZs from model years 2013 and 2014, as well as Fiestas from model years 2012 to 2014. A "broken pawl spring tab" is the culprit, potentially keeping doors from latching shut. According to Ford, even if the door does shut, it could come open again without warning. The affected Fiestas were built between February 1, 2012 and May 31, 2013 at the Cuautitlan, Mexico factory. The Fusion and MKZ siblings, meanwhile, were screwed together at Hermosillo Assembly in Mexico between July 1, 2012 to May 31, 2013. Ford is aware of three minor reports of door malfunctions. In two cases, the door bounced back open, quite literally hitting drivers on their way out. In the third case, a door swung open of its own accord while a driver was attempting to park, hitting another vehicle. Ford will notify owners, who will need to report into dealers to have all four latches replaced. Scroll down for the official press release. Related Video: APR 24, 2015 | DEARBORN, MICH. FORD MOTOR COMPANY ISSUES SAFETY RECALL IN NORTH AMERICA FOR DOOR LATCH ISSUE ON FORD FIESTA AND FUSION, LINCOLN MKZ Ford Motor Company is issuing a safety recall for approximately 390,000 2012-2014 Ford Fiesta and 2013-2014 Ford Fusion and Lincoln MKZ vehicles for a door latch issue. The door latch in these vehicles may experience a broken pawl spring tab, which typically results in a condition where the door will not latch. If a customer is then able to latch the door, there is potential the door may unlatch while driving, increasing the risk of injury. Ford is aware of two allegations of soreness resulting from an unlatched door bouncing back when the customer attempted to close it, and one accident allegation when an unlatched door swung open and struck an adjacent vehicle as the driver was pulling into a parking space. Affected vehicles include certain 2012-2014 Ford Fiesta vehicles built at Cuautitlan Assembly Plant, Feb.

Ward's Automotive Ten Best Engines of 2014 dominated by diesels, turbos

With the Car and Driver Ten Best decided, the North American Car and Truck of the Year finalists announced and Cadillac, Ram and Subaru chalking up wins with Motor Trend, it's fair to say that the automotive awards season is in full swing. The next set of trophies to be handed out will be from Ward's Automotive, which has announced the winners of its 2014 10 Best Engines.
The latest contest was marked by the widespread emergence of diesel power and the continued success of turbocharged engines. There was even an electric motor on this year's list. In fact, only three of the ten winners were naturally aspirated and only two winners returned from last year.
"We weren't looking to throw the bums out, as they might say about an election. We were just really impressed with the flood of new powertrains," said Ward's Automotive Editor-in-Chief Drew Winter. Those new powertrains include the 83-kilowatt electric motor from the Fiat 500e, the 1.0-liter, EcoBoost three-cylinder from the Ford Fiesta and the 2.0-liter turbodiesel from the Chevrolet Cruze.
