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.

2014 Ford F-150 gets CNG option

Ford is toiling away, installing heavy-duty engine components into select 3.7-liter V6s to allow them to run on compressed natural gas (CNG) and liquid petroleum gas (LPG) in addition to gasoline. That's nothing new, but now, Ford has announced that it will offer the 2014 F-150 with this engine configuration, bringing the Blue Oval's total number of CNG/LPG-friendly vehicles up to eight. The F-150 will be the only half-ton pickup on the market that can run on these gases.
Ford will charge $315 per vehicle to equip the optional engine, but the trucks won't be ready to run on the alternative fuels straight from the factory and must be upfitted with additional equipment. A Ford Qualified Vehicle Modifier will install a separate fuel system for the compressed gases at a cost of $7,500 to $9,500, depending on fuel tank size. With the right-size tank, the F-150 equipped with the CNG/LPG-prepped engine can go 750 miles on one tank of gas, according to Ford, averaging 23 miles per gallon.
The practice of offering flex-fuel vehicles is gaining momentum as businesses take advantage of cheap gas. CNG can be bought for $2.11/gallon on average (per gasoline equivalent), and sometimes for as little as $1.00 in some parts of the US, Ford states. "With the money saved using CNG, customers could start to see payback on their investment in as little as 24 to 36 months," says Jon Coleman, Ford's fleet sustainability and technology manager. The automaker expects to sell a total of 15,000 CNG/LPG-prepped vehicles in the 2014 model year.

Toyota, Ford decide to end hybrid collaboration before it starts

Not all so-called Memorandum of Understanding pacts end in actual collaborations. For instance, after a two-year "feasibility study," Toyota and Ford have just announced that they will not be developing hybrid systems for use in light trucks and SUVs as previously planned, and the two automakers will instead continue to develop their own hybrid technology independently.
The would-be collaboration was first announced in August of 2011, and would have seen a rear-wheel-drive hybrid platform that would "improve the efficiency of trucks and SUVs while still allowing them to be driven in the way customers expect," according to our initial post on the topic.
Keep in mind that this announcement isn't to say we shouldn't expect hybrid pickups and SUVs from the two automakers, but that they probably aren't coming very soon - Ford says it will have a system "before the end of this decade" and we haven't heard much from Toyota on the hybrid truck front since the 2008 A-BAT Concept (pictured above) - and that they will not share any components between them (and they never have, for what it's worth).
