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.

1969 Ford Talladega GPT Special is a SEMA showstopper

Rad Rides by Troy has unleashed upon the SEMA crowds this custom 1969 Ford Torino Talladega GT Special, and it's a beauty. The car calls to mind the classic Holman Moody stock cars that circled NASCAR tracks in the late 1960's, driven by the likes of Mario Andretti, Dan Gurney and David Pearson, who won the Grand National title in both 1968 and '69 in a Ford Torino.
Even though it has plenty of stock-car influence, there's nothing retro about the car's design or powertrain, other than the fact that the engine is based on a Ford Boss 429 block. Fuel injection, aftermarket aluminum heads and a high-tech custom computer system combine to send 750 reliable ponies to the rear wheels through a Tremec five-speed manual transmission. Brakes measure 14-inches all around, with six-piston Wilwood calipers up front and four-piston units out back.
There's custom bodywork abound, painted in a two-tone Tennessee Whiskey Gold and Daytona Sand finish. Check out all the amazing details in the image gallery below, and scroll down to read all about it in designer Troy Trepanier's own words.

Ford Mustang, F-150, Expedition, and Lincoln Navigator recalled

The Basics: Ford will recall 201,900 examples of the 2011-2012 F-150, 2012 Expedition, 2012 Mustang, and 2012 Lincoln Navigator. The affected vehicles have the 6R80 transmission. Of the total, there are 84,000 of them in the United States and 17,900 in Canada. The Problem: The output speed sensor on the vehicle's transmission lead frame can force the gearbox to downshift into first gear. If this happens at high speed, it could cause the rear tires to slide or lock up. Injuries/Deaths: There are no reported injuries, but Ford know of three accidents related to this problem. The Fix: Dealers will update the powertrain control module software to eliminate the problem, and they'll also replace the transmission lead frame. If You Own One: Ford will begin notifying affected customers by mail on May 23.

Details are as follows: Ford issues safety recall and customer satisfaction program for certain 2011-2012 Ford F-150, and 2012 Ford Expedition, Ford Mustang and Lincoln Navigator vehicles in North America to update powertrain control module software and inspect for certain diagnostic trouble codes Ford is issuing a safety recall for approximately 202,000 2011-2012 Ford F-150, and 2012 Ford Expedition, Ford Mustang and Lincoln Navigator vehicles for a potential issue with the output speed sensor on the vehicle's transmission lead frame. Under certain conditions, the transmission controls could force a temporary downshift into first gear. Depending on the speed of the vehicle at the time of the downshift, the driver could experience an abrupt speed reduction that could cause the rear tires to slide or lock up. This condition could result in loss of vehicle control, increasing the risk of a crash. Ford is aware of three reports of accidents and no injuries related to this condition. Affected vehicles are equipped with a 6R80 transmission and include certain 2011-2012 Ford F-150 vehicles built at Dearborn Truck Plant and Kansas City Assembly Plant, Aug. 19, 2011 through March 9, 2012; 2012 Ford Expedition vehicles built at Kentucky Truck Plant, Aug. 19, 2011 through Dec. 19, 2011; Ford Mustang vehicles built at Flat Rock Assembly Plant, Aug. 19, 2011 through Feb.
