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 could make as much as $13k profit for every F-150

The Ford F-Series is a perennial member of the US bestseller list with the title in its brawny grasp for over 30 years, and the truck ranks as the top-selling model over $50,000 in the country. It shouldn't come as a shock then that the model is a major buttress of Ford's bottom line. Have you ever wondered just how vital the trucks are to the Blue Oval's health, though? Some math based on recent figures suggests they might be even more important than you think. Automotive News recently did the calculation and came up with that each F-150 sold contributed about $13,333 to the company's profits. That number was based on a statement from Ford CFO Bob Shanks that the automaker could have made another $1 billion in North America for the first quarter with a repeat of last year's sales of the F-150 and Edge, with 60,000 more trucks and 15,000 additional crossovers. If those 75,000 missing vehicles cost the company $1 billion, then they averaged $13,333 each. Also, the F-150 makes up 80 percent of the lost sales, so you might even conclude that each pickup brings even more money into Ford. Automotive News also extrapolates further. Based on a forecast of 800,000 F-Series sales this year, that's about $10.7 billion going into Ford's coffers. Obviously, these figures are far from exact since they are based on a single statement from the automaker's CFO. Autoblog reached out to Ford to see if the numbers were accurate, but the Blue Oval wouldn't comment on vehicle profitability. However, AutoPacific analyst Dave Sullivan suggests these figures could be on the right track, if a bit high. "The rough guess has been $10,000. Obviously that is a little different for a $60k truck vs a regular cab 4x2 work truck, but $10,000 is the ball park that is used," he said to Autoblog. If you ever wonder why Ford might be loathe to bring the smaller Ranger back to the US when it's available elsewhere, these huge profits are likely part of the answer. The Blue Oval has little reason to cut into the sales of a model that makes the brand billions. Related Video:
