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 unveils all-new 2016 F-650 and F-750 at NTEA

Medium-duty work trucks might not be the most exciting vehicles, but they perform necessary jobs everyday. Ford is in the process of a complete refresh of its entire commercial vehicle lineup over the next 18 months, and it is debuting the all-new versions of its F-650 and F-750 trucks at the NTEA Work Truck Show in Indianapolis, IN.
"The all-new F-650/F-750 allow us to leverage our strengths and sales leadership in Classes 1 to 5 to create a better F-650/F-750 that's designed, engineered and built by Ford in the USA," said Ford spokesperson Mike Levine to Autoblog via email.
Huge amounts of torque is vital for trucks like these, and both models are offered with some of Fords biggest engines. Buyers can opt for either the 6.7-liter Power Stroke V8 diesel with TorqShift 6-speed automatic with available power takeoff or a gasoline-fueled 6.8-liter V10 with a 6-speed automatic. The V10 can also be ordered from the factory to be fueled by compressed natural gas or liquid propane gas.

Ford settles class action suit over defective Navistar diesel engines

The 2003 Ford F-Series Super Duty (shown above) introduced the 6.0-liter Power Stroke diesel supplied by Navistar, and while that is an engine Ford would love to forget, it's now one step closer to putting that particular problem behind it. Automotive News is reporting that Ford has settled a class-action lawsuit brought on by problems with this engine that started right out of the gate and ultimately broke up the 30-year relationship between Ford and Navistar.
Owners and lessees of 2003-2007 Super Duty trucks and E-Series vans equipped with the 6.0-liter Power Stroke are eligible for deductible reimbursements of between $50 and $200 from the original five-year/100,000-mile engine warranty, while Ford is paying out as much as $825 for out-of-warranty engine repairs. These repairs may include the exhaust gas recirculation (EGR) cooler, EGR valve, oil cooler, fuel injectors and turbocharger, but are only covered if the components failed before six years or 135,000 miles.
In total, Ford has agreed to pay about 50 percent of the value of the repairs and deductibles paid by its customers who submit a claim before the end of this year, and $150,000 is going to the 16 named plaintiffs in the case; Navistar was not included in the lawsuit.
