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.

Next Ford F-150 delayed for aluminum body panel issues?

The timetable for next-generation Ford F-150 may be in trouble if a report from The Truth About Cars is true. The next F-150 is slated to make extensive use of weight-saving aluminum in its body, but the aluminum alloy provided by suppliers hasn't met Ford's requirements in the earliest phases of pre-production, according to the report.
The F-150 represents a huge portion of Ford's profits and is the best-selling truck in the US, even in the face of increased pressure from cross-town rivals General Motors and Ram. While the current truck is treading water against its competition, we'd be lying if we said the F-150 weren't growing quite long in the tooth.
If production of the next-generation of the Ford cash cow, said to be based on the Atlas Concept from the 2013 Detroit Auto Show (pictured above), is delayed, it could be bad for Ford. Production at Ford's Dearborn Truck Plant is already set to be delayed six to ten weeks, missing an internal on-sale deadline of Memorial Day.

NHTSA and Ford investigating steering issues in Crown Vic, Grand Marquis and Marauder

There may be more steering woes for the Ford Crown Victoria. The National Highway Traffic Safety Administration has opened a preliminary evaluation into the Crown Vic and Mercury Grand Marquis from the 2004 to 2007 model years and the Mercury Marauder for the 2004 and 2005 model years because the steering shaft can jam. The issue could potentially affect an estimated 500,000 vehicles.
According to the regulator, there is a possibility that the driver's side heat shield for the exhaust manifold can rust, dislodge, and then wedge into the steering shaft. If this occurs, it leads to a situation where the driver can no longer control the car.
NHTSA has received five complaints of this happening, including one alleged case with an injury. In that situation, the car was driving onto the highway, lost control and rolled over. One occupant was hurt in the accident.
