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.

2015 Ford Transit

As a segment, fullsize vans are stealth-fighter invisible on most consumers' radar. Visit a dealership for any of the four brands that offer them and you'll be lucky to find even one on display. These are commercial vehicles primarily, even more so than pickup trucks. Vans are the shuttles for plumbers, caterers, carpenters, concrete layers, masons, electricians, florists and flooring, and a huge part of this country's productivity is accomplished using them. At the moment, Ford is the 800-pound gorilla in that room - fully 41 percent of commercial vehicles wear a Blue Oval. So when Ford announced three years ago it would be ditching its commercial bread-and-butter E-Series, it meant the Transit that would be replacing the Econoline had huge, 53-year-old shoes to fill.
We were still a bit nostalgic about Econoline vans going away until going directly from the Transit first drive in Kansas City to an E-350 airport shuttle. Climb up through the Econoline's tiny double doors and bang your head on the opening, crouch all the way to your seat then enjoy a loud, rattle-prone, creaky, harsh ride on beam-hard seats while struggling to see out the low windows. This is an experience nearly every traveler has had. By comparison, the Transits we'd just spent two days with were every bit of the four decades better they needed to be. It cannot be understated just how much better the Transit is in every single way. The load floor is barely more than knee high. There's a huge side door, and hitting your head on a door opening is nearly impossible. Stand up all the way if you're under six-foot, six-inches - no more half-hunching down the aisle. There are windows actually designed to be looked out of. The ride is buttery smooth, no booming vibration from un-restrained metal panels and no squeaks. Conversations can be held at normal levels rather than yelling over the roar of an ancient V8. The seats are comfortable. The AC is cold. There are cupholders.
Enough anecdote-laying, what's in a Transit? We're talking about a very fullsized unibody van that's enjoyed a 49-year history in Ye Olde Europe. This latest iteration is part of the "One Ford" initiative, so it was designed as a global offering from the get-go, eschewing the body-on-frame construction the E-Series has used since 1975. Instead, the Transit integrates a rigid ladder frame into an overall frame construction made of high-strength cold-rolled and boron steel. The suspension is a simple but well-tuned Macpherson strut array up front with a rear solid axle and leaf springs.
