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.

Volvo to shake off Ford ties with new platforms, engines

It would seem Volvo is finally getting around to throwing all of Ford's things out of the apartment. Automotive News reports the Swedish automaker is preparing to unleash a range of new engines as well as a fresh platform designed entirely in house. The powerplants include an all-new four-cylinder engine set to bow before the end of this year before arriving in the US by 2014. Shortly thereafter, the world should get its first glimpse at the next-generation XC60, which will the company's first model to make use of the Volvo scalable platform architecture (SPA). US buyers can expect to see that machine on their roads by early 2015.
The next V70 and S80 will also use the SPA, though those models will carry V90 and S90 designations when they hit dealer floors. But that doesn't mean Volvo has completely weened itself off of Ford technology. The V40 will continue to ride on Ford bones until the model's next chassis can be co-developed between Volvo and Geely.

Ford recalls 422,000 SUVs for rear view camera display that may fail

WASHINGTON — Ford is recalling 422,000 sport utility vehicles in the U.S. because the video output may fail, preventing the rear view camera image from displaying. The recall covers 2020 through 2023 Ford Explorer, Lincoln Aviator, and 2020-2022 Lincoln Corsair SUVs with a 360-degree camera. The recall expands and replaces prior Ford callbacks for the same issue in 2021 and 2023. Ford last year updated the image processing module (IPMB) software in an effort to address the issue. Ford said on Thursday it is "working together with suppliers to identify root cause and provide the correct remedy as quickly as possible". The National Highway Traffic Safety Administration (NHTSA) said the loss of the rear view camera image can reduce the driver's rear visibility, increasing the risk of a crash. Owner notification letters are expected to be mailed on June 26. Last year, Ford said it had reports of 17 minor crashes relating to the recall issue and more than 2,100 warranty reports but no reports of injuries. The NHTSA in August 2021 opened an investigation after Ford in 2020 recalled 620,246 vehicles for another rear camera issue. The investigation is reviewing if Ford had recalled the vehicles in a timely fashion and if it recalled enough vehicles. Recalls Ford Lincoln Crossover SUV
