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.

This Mercury Cyclone is an American Muscle Car in Norway

The picturesque Norwegian countryside certainly doesn't seem like the natural stomping grounds for a 1969 Mercury Cyclone, but owner Alexander Brevik makes the odd combo look like an ideal match. Even with the beautiful surroundings, Brevik sees no need to enjoy the scenery; he'd much rather just be driving this vintage muscle car. Take a ride with him in the latest clip from Petrolicious. Like many of us, Brevik's automotive obsession started at childhood, and today he has amassed a multitude of projects to wrench on. While he loves working on all of these cars, we all need a break sometimes, and that's what the Cyclone is for. Even when the rest of his collection isn't running, this orange beauty is always ready to go. Brevik may not pay much attention to the landscape, but Petrolicious makes the muscle car look fantastic in the Norwegian woods nonetheless. With its rumbling V8 engine and three-speed manual, this Cyclone turns out to be a perfect cruising companion in the Land of the Midnight Sun. And if you just can't get enough of classic muscle cars and the people who love them, check out our video coverage of the 2015 Woodward Dream Cruise in Detroit down below. Related Video:

Junkyard Gem: 1991 Mercury Capri

Ford has gotten a lot of use out of the Capri name in the United States. First, there was the Lincoln Capri in the 1950s, followed by the Ford Capri Mk1 (which was sold by Mercury dealers in the USA but never actually badged as a Mercury). Then came the 1979-1986 Mercury Capri, built on the very successful Fox Platform and essentially a clone of the Mustang. Finally, in 1991, the Australian Ford Capri came to the United States. Here is an example of this rare car that I spotted in a Northern California self-service yard not long ago. Mechanically speaking, the 1991-1994 Capri was a Mazda 323 under the skin, complete with a member of the same B-series engine family that went into such cars as the Miata and Ford Escort. So, for a few years in the early 1990s, car shoppers who wanted a sporty Mazda convertible could choose between a Miata and a Capri. The Capri had front-wheel-drive, but could be had with factory turbocharging. These cars were reliable and fun, but had a tough time competing with the Miata in the showroom battles. You'll see the occasional example now and then, but most of the 1991-1994 Capris have met the same fate that awaits this one. Related Video:
