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 recalls 1.9m cars and crossovers for defective airbags

The Basics: Ford is recalling a total of 1,898,728 vehicles to replace defective Takata front passenger-side airbags. This includes the 2007-2010 Ford Edge, 2006-2011 Ford Fusion, 2005-2011 Ford Mustang, 2007-2011 Ford Ranger, 2007-2010 Lincoln MKX and 2006-2011 Lincoln MKZ, Zephyr and Mercury Milan vehicles built in North America. The Problem: The defective airbags have been linked to ruptures that can send metal fragments at the passenger, due to deteriorating propellant. Injuries/Deaths: Ford claims it's not aware of any injuries due to the problem, but rupturing Takata airbags have been linked to a series of serious injuries and deaths. The Fix: Dealers will replace the passenger-side frontal airbag at no charge to the customer. If you own one: Look out for a letter from the manufacturer to arrange service at your local dealer. If you'd like to check if your vehicle is affected, click on the safety recalls link on Ford.com and enter your VIN. Related Video:

Ford Announces Free Brake-Pad Offer If Customers Stop By Dealers

These days, when you buy a new car, it's not unreasonable to expect a certain period of free maintenance to come along as well. Sometimes this is through the life of the warranty, in other cases a little less. But Ford Motor Company is going beyond those deals for at least one part of its cars. As of now, if you buy a set of Motorcraft brake pads for a Ford, Lincoln or Mercury model, you get free replacements for as long as you own the vehicle. The offer is good at Ford or Lincoln dealers and Quick Lane Tire & Auto Centers. "We will replace the pads for as long as you own the vehicle," said Elizabeth Weigandt to Autoblog. She did clarify that the Motorcraft pads are generally for models from the '90s or newer. Also, to take advantage of this program, a person must return to the same dealer each time to get the free parts. Of course, Ford isn't just handing out brake pads to anyone who walks by; there are certain stipulations. First, the components have to be worn down to less than three millimeters to be eligible, and the buyer still has to pay for the labor to install them. If the model is used as a fleet vehicle for commercial purposes like as a taxi or limousine, this offer also doesn't apply; the same thing for racecars. On the plus side, if you recently bought a set of pads from one of the participating locations, you're still in luck. The deal covers parts purchased as of July 1. "This program reflects our commitment to providing customers with an excellent ownership experience regardless of the age of their vehicle," said Frederiek Toney, President of Ford Customer Service, in the company's announcement of the offer.
