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 recalls 591,177 vehicles in four separate campaigns

Ford is issuing recalls for a total of 591,177 vehicles worldwide, in four separate campaigns. The announcement comes just days after the discovery of door-latch problems in 390,000 of the automaker's cars. The largest of these new recalls covers 518,313 examples of the Ford Fusion and Lincoln MKZ from the 2013-2015 model years, plus the 2015 Edge. Of these, 487,301 of are in the US and 31,012 are in Canada. For vehicles in cold-weather areas, the bolts that hold the steering gear motor can corrode and fracture. If this happens, it could cause the power steering to fail, but manual control would be retained. There are no reported accidents or injuries from this problem. To fix things, dealers will replace the bolts and seal them. The next campaign covers 50,157 examples of the 2014 Focus, Edge, Escape, and Transit Connect, plus the Fiesta from 2014 and 2015. Of these, 45,505 are in the US, 4,618 in Canada, and 34 in Mexico. All of them exhibit a problem with the fuel pump where the nickel plating can cause the part to seize and the engine to stall, if this occurs. (All of which sounds like recent problems with Nissan and BMW models.) According to Ford, there is one allegation of an accident from this problem. Dealers will replace the fuel delivery module to fix the problem. Ford is also recalling 22,616 units of the 2015 Lincoln MKZ because when the headlights are on, the parking lamps are brighter than they are allowed to be. The light could affect the vision of other drivers. This campaign includes 21,435 of them in the US, 1,066 in Canada and 115 in Mexico. There are no accidents or injuries from the issue, but Ford is updating the software to dim the lights on these sedans. Finally, Ford has a safety campaign for 91 examples of the 2015 F-150 because an underbody heat shield might not be properly installed or not present at all, which can be a fire risk. There are no reports of any actual accidents or fires, though. The affected pickups will have the parts replaced or added, as necessary after a dealer inspection. To see the specific build dates for the models affected by each of these campaigns, you can read about them in the press release below.

2015 Ford Mustang EcoBoost loses big power on 87 octane

The 2015 Ford Mustang with the 2.3-liter EcoBoost four-cylinder is a pretty potent package on paper. With 310 horsepower and 320 pound-feet of torque, it boasts better performance numbers than the 3.7-liter V6, but with better fuel economy as an added benefit. However, if you're in the market for one of these boosted 'Stangs, you should probably keep in mind that it really prefers to gulp premium, 93-octane fuel. It can drink 87-octane swill in a pinch, but you're going to find significantly less power underfoot when pulling away. While it's not shocking that the ponies are dialed back with a lower grade of gasoline, an alleged page from a Ford training manual obtained by Mustang 6G purports to show just how much power is lost, though. According to this document, the 2.3-liter EcoBoost makes 275 horsepower and 300 pound-feet of torque when running on lower octane fuel. That's a substantial reduction of about 11.3 percent compared to when the engine drinks 93 octane. Interestingly, according to Mustang 6G, that finding was a bit better than expected, because a Ford engineer reportedly said power would be down about 13 percent without altering peak torque. In speaking with Autoblog, Paul Seredynski of Ford powertrain communications, objected to part of this document. While he couldn't confirm the specific losses listed for the Mustang EcoBoost, "torque remains unchanged" with lower octane gasoline, Seredynski said. He speculated this training manual page was "possibly from before the engine was certified" and therefore showed incorrect figures. Serendynski did confirm that the automaker recommends using 93 octane, and like all modern engines, the software adapts if it's lower. "Peak power would be reduced" by using a lesser grade, he confirmed.
