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 F-150 SVT Raptor sales jumping to new heights

Ford can't seem to build F-150 SVT Raptors fast enough. The off-road-ready trucks have been one of the Blue Oval's most reliable sellers, with record sales in eight of the last 10 months and a 14-percent jump in 2013. That's impressive enough, considering that the least expensive Raptor starts at $44,000. Factor in the modded F-150's fuel economy (it's rated at 11 miles per gallon in the city and 16 on the highway) and a national average gas price, as of this writing, of $3.55 per gallon, and its success is as unlikely as Ford's home team, the Detroit Lions, winning the Super Bowl this year (sorry, Lions fans, we're just quoting the experts in Vegas...).
Yet for some reason, Raptors spend an average of just 15 days on dealer lots before being snapped up, which is a quarter of the 60-day industry average. According to Ford's truck group marketing manager, Doug Scott, it's capability that keeps the Raptor selling strong. "What's helping drive Raptor sales is that Raptor delivers unmatched off-road performance to our customers. Raptor is also proof of our commitment to offer a truck for every customer and continuously improving them to meet our customers' evolving needs."
To address the strong demand for Raptors, Ford will bump production from three trucks per hour to five. Not much, we agree. But building an extra 48 trucks per day, at most, seems like a prudent way of addressing demand without oversaturating what is ultimately a niche market. Check out the press release below for more.
