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.

Bosch fined $57.8 million by DOJ for price fixing and bid rigging

The US Department of Justice has been investigating bid rigging and price fixing among automotive parts suppliers for years, and so far the agency has leveled nearly $2.5 billion in fines against 34 companies. The latest business to be caught in this ongoing crackdown is Germany's Robert Bosch GmbH (Bosch), the world's largest independent auto component maker, and it agrees to pay a $57.8 million criminal fine to the Feds. According to the DOJ, Bosch has agreed to plead guilty to pricing fixing and bid rigging for spark plugs and oxygen sensors supplied to the former DaimlerChrysler, Ford and General Motors. The rigging is said to have occurred between January 2000 and July 2011. Bosch also allegedly played foul with starter motors sold to Volkswagen from January 2009 until at least June 2010. Bosch and other companies allegedly conspired on the pricing for bids to submit to automakers, and sold the parts at noncompetitive prices. The DOJ filed a one-count felony charge in US District Court for these actions. The company's plea is still subject to court approval, though. Bosch is only the third European company to be charged in this investigation, according to the DOJ. So far, many of the fined businesses have been from Japan, including Takata, NGK and others. Some execs have claimed price-fixing has been the standard operating procedure in the auto parts industry for a long time. Robert Bosch GmbH Agrees to Plead Guilty to Price Fixing and Bid Rigging on Automobile Parts Installed in U.S. Cars Robert Bosch GmbH, the world's largest independent parts supplier to the automotive industry, based in Gerlingen, Germany, has agreed to plead guilty and to pay a $57.8 million criminal fine for its role in a conspiracy to fix prices and rig bids for spark plugs, oxygen sensors and starter motors sold to automobile and internal combustion engine manufacturers in the United States and elsewhere, the Department of Justice announced today. According to the one-count felony charge filed today in the U.S. District Court of the Eastern District of Michigan, Bosch conspired to allocate the supply of, rig bids for, and to fix, stabilize and maintain the prices of, spark plugs and oxygen sensors sold to automobile and internal combustion engine manufacturers such as DaimlerChrysler AG, Ford Motor Company, General Motors Company and Andreas Stihl AG & Co., among others, in the United States and elsewhere.

NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.
