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.

Lincoln MKC will be renamed the Corsair in 2021, probably

Lincoln will be renaming its MKC crossover, calling it the Corsair instead. Automotive News is reporting that the recently trademarked, yet storied Ford model name Corsair will be affixed on the 2021 model year crossover. The report says Ford has already told its U.S. dealers about the name at an Orlando meeting last month. Ford has a long history with the Corsair nameplate in the States and abroad: Most recently, it has been in use in Australia in the early 1990s, in the UK in the 1960s, and before that Ford offered an Edsel Corsair in the late 1950s. Even if an Edsel connection might not be the best possible thing for a Ford product, let alone a Lincoln, it might serve the crossover well as Ford moves to ditch the MK naming convention it's used for Lincoln for the past decade. Still, the manufacturer is said to have cautioned dealers it might opt out of using the Corsair name before production time. At the same meeting, Ford reportedly showed the next-generation Escape, the Explorer, a battery electric crossover dubbed the Mach 1, a yet-unnamed small SUV (which might be the Bronco) , and a new Lincoln Continental complete with suicide doors. The MKC will still receive a refresh for next year, retaining its letters-name for a couple of years before the bigger redesign for 2021. Currently, the MKC is the strongest-selling Lincoln product in China, and it brings in numerous new Lincoln customers there. In the U.S. it's outsold by the MKX crossover and is neck-and-neck with the MKZ sedan.
