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.

Ford cuts F-150 fuel use through CNG-capable fleet sales, EcoBoost

The possibility of $1-a-gallon fuel would make a lot of US governmental entities sit up and take notice. The state of Oklahoma and the city of Dallas are making that happen. Those two entities are buying up a bunch of Ford F-150 pickups retrofitted to run on compressed natural gas (CNG), all in the name of cost savings and emissions reduction. Oklahoma is buying 256 of the F-150s, while Dallas is buying another 65. The trucks, which cost between $6,000 and $9,500 to retrofit (on top of the original price), can run on either CNG or liquefied petroleum gas (LPG). And while that's a substantial hit, conversion costs are typically paid back in three years thanks to lower refueling costs. CNG prices are as low as $1.07 a gallon in parts of Oklahoma. How much lower? The national average price for CNG is about a buck and a half less than the $3.67 average per-gallon cost of gasoline. And CNG prices are as low as $1.07 a gallon in parts of Oklahoma, where CNG is plentiful. CNG also cuts tailpipe greenhouse gas emissions by about 20 percent compared with gasoline, while the retrofitted trucks can go as far as 450 miles from their CNG tanks in addition to the 300-mile range from their conventional tanks. That's useful in a bit state like Texas. This week, the US Energy Department trumpeted a $5.9-billion loan program that Ford accessed to upgrade its factories for production of its EcoBoost engines, noting that Ford has sold a half-million F-150 trucks with EcoBoost engines. Those trucks have collectively cut fuel use by almost 57 million gallons of gas during the past three-plus years. Check out Ford's press release on the F-150 purchases below and the Energy Department's statement about its loan program here. OKLAHOMA, DALLAS ORDER 300-PLUS CNG-CAPABLE FORD F-150 PICKUPS AS DEMAND GROWS FOR ALTERNATIVE FUEL OPTION The state of Oklahoma and its agencies to buy 256 Ford F-150 trucks prepped to run on compressed natural gas; Dallas orders 65 for its fleet 2014 F-150 available with gaseous-fuel prep option on 3.7-liter V6 engine; can run on CNG or liquefied petroleum gas (also called propane autogas) By summer, Ford will offer eight vehicles that can run on clean-burning, affordable CNG; the company is on track to sell more than 15,000 such vehicles in 2014 The state of Oklahoma, its agencies and the city of Dallas have ordered a total of 321 Ford F-150 pickups that can run on compressed natural gas.

Why 2015 is going to be a huge year for trucks

Nissan chief executive Carlos Ghosn took center stage to introduce the 2016 Titan last week at the Detroit Auto Show. He spoke of the truck's new features, impressive Cummins V8 diesel engine and the extensive amount of time and money required to build a modern, competitive pickup truck. "We have done all of this because we see opportunity – an opportunity in the unmet needs of today's American truck customers," Ghosn said. He was speaking about the Titan, but his thoughts echo the industry's mindset: When it comes to trucks, find an opportunity and attack. Even with CAFE regulations looming and fickle consumer preferences, investing in trucks is a no-brainer for automakers. Some consumers will always need a truck for their job or lifestyle. And some people will always want one, whether they need it or not. With that in mind, here are four reasons why the pickup-truck sector is more important than ever and poised for growth in 2015. View 24 Photos The Nissan Titan Is Back Okay, it never left, but the Titan hadn't been redesigned since its launch in 2003, and Nissan sold more NV200s than Titans in 2014. It's an understatement to say the truck was languishing. That all changes with the 2016 model. The Titan will come in two variants, a traditional fullsize competitor and the Titan XD. The XD will lead the market launch, and it arrives late this year. It's pitched as a "whitespace" offering, Nissan sales and marketing vice president Fred Diaz said. The idea is to offer something in the general size and price range of a fullsize truck, but also have some of the capability of a heavy-duty truck. The XD uses a fully boxed ladder frame, the chassis design from Nissan's commercial division, and the wheelbase is about 20 inches longer than other Titan models. The XD, which Nissan is calling the flagship of the line, will be the only model with the 5.0-liter Cummins turbodiesel V8. It produces 310 horsepower and 555 pound-feet of torque, while being able to tow 12,000 pounds. V6 and V8 gasoline models will also be offered on the Titan XD and the standard, non-XD model. When production ramps up, the Titan will be sold with several cabs, beds and trims. New features include trailer sway control, an integrated trailer brake controller, more storage options in the cabin and even laminated front and rear side glass to reduce outside noise. All of this has given Nissan fresh confidence in an area where it admittedly has been lacking. "We can compete," Diaz told Autoblog.
