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.

Question of the Day: Most degraded car name?

When Ford came up with a not-so-sporty version of the Pinto and slapped Mustang badges on it in 1974, that was a low point for the Mustang name. When Chrysler applied the venerable Town & Country name on perfectly functional but unglamorous minivans, it saddened many of us. But perhaps the biggest demotion for a once-proud model came when, in 1988, General Motors imported a misery-enhancing Daewoo from Korea and called it the Pontiac LeMans. The original Pontiac LeMans was a great-looking midsize car with fairly advanced (for the time) suspension design and engine options including potent V8s and a screaming overhead-cam straight-six. The Daewoo-based Pontiac LeMans was a cramped, shoddy hooptie that served only to ruin the LeMans name forever, while stealing sales from the Suzuki-based Chevrolet Sprint. Sure, using the once-respected Monterey name on the Mercurized Ford Freestar was bad, but Mercury didn't have long to live at that point. I say the downward spiral of the LeMans name was the most agonizing in automotive history. What do you think? Related Video: This content is hosted by a third party.

Preposed class-action lawsuit targets 'defective' MyFord Touch

A national law firm, Hagens Berman Sobol Shapiro LLP, has filed a proposed class action lawsuit whose presupposition is that MyFord Touch is defective. Specifically, the complaint states that the system - as well as the MyLincoln Touch and MyMercury Touch clones - often freeze, fail to respond to voice or touch commands and have issues connecting to mobile phones.
According to Hagens Berman managing partner Steve Berman, MyFord Touch is a theoretically "brilliant idea" that falls short in actual execution. Said Berman in a press release, "In reality, the system is fundamentally flawed, failing to reliably provide functionality, amounting to an inconvenience at best, and a serious safety issue at worst."
Other MFT issues enumerated within the 41-page filing include problems controlling the window defroster, rear-view camera and navigation system. The suit maintains that Ford is aware of the problem but has yet to submit a workable and acceptable solution to MFT customers. Scroll down if you'd like to read the full press release.
