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.

John Hennessey's personal 2015 HPE700 Supercharged Ford Mustang GT hits 195 mph

Dressed in a coat of menacing black paint, the 2015 Hennessey Performance HPE700 Supercharged Ford Mustang GT definitely looks like one mean muscle machine. The 717-horsepower 'Stang proved that it can back up that aggressive appearance recently when company founder John Hennessey took his personal example to see just how fast it would go. The result down the 1.1-mile straight at the Continental Tires Proving Grounds in Uvalde, Texas, was over 195 miles per hour. The Mustang is nothing but a black blur and wall of supercharger wail as it buzzes by the camera at top speed. Despite the strong result, Hennessey doesn't seem done with the 'Stang yet. The car still seems to be pulling when it hits the rev limiter, and there's some straight track left ahead. After getting out, John Hennessey immediately says he thinks 200 mph is possible. The heart of the HPE700 is a 2.9-liter Roots-Type supercharger running at 7.25 psi. That's a pretty massive blower, especially when considering the 2.4-liter unit on the Hellcat V8. The engine also gets upgrades like improved injectors, a new fuel pump, stainless steel exhaust and recalibrated management. The company claims the upgraded Mustang can hit 60 in around 3.6 seconds and do the quarter-mile in 11.2 seconds at 131 mph. Prices for the package start at $59,500, but this one would would ring up for $65,874. Hennessey Performance is limiting production to 500 of them for the 2015 model year. 2015 HPE700 Supercharged Mustang Rockets to 195.2 mph John Hennessey takes his personal Mustang GT on a Texas road trip Uvalde, Texas-Everything is bigger in Texas, especially when it comes to automotive performance. Texas also lays claim to the highest posted speed limit in America at 85 mph. Enter the team from Hennessey Performance Engineering (HPE) who are located just west of Houston. John Hennessey and his merry band of performance car builders like to go fast, so much so that they have their own 1/4 mile dragstrip next to their workshop. Recently, the Hennessey team wanted to test their 717 horsepower HPE700 Supercharged Mustang development car (John's personal car and occasional daily driver) beyond the 130+ mph speeds that they have seen on the dragstrip. "Thankfully, we had recently received an invitation from the guys at the Continental Tires proving grounds in Uvalde to come over and do some testing on their 8.0 mile high speed oval", said Hennessey.
