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, GM still doing new business with Takata amidst airbag crisis

Lengthy vehicle development times make it difficult for automakers to cut and run from the supplier. You might expect automakers to be fleeing any connection with beleaguered supplier Takata in the wake of the company's exploding airbag inflator crisis. After all, with a Senate hearing, pending lawsuit, plummeting stock value and demand for a national recall, the tier-one supplier isn't at its strongest right now. However, years of cooperation mean that automakers are standing by Takata, and necessity may be playing a role, as well. About 39 percent of Takata's business comes from airbags, and seatbelts make up another significant chunk of the operation too, says Bloomberg. The long-term relationships and lengthy vehicle development times make it difficult for automakers to cut and run from the supplier. "Takata has so much product breadth that I don't really see that they could just disappear," said AutoPacific analyst Dave Sullivan to Bloomberg. For example, Takata helped develop the unique front center airbag with General Motors in models like the Chevrolet Traverse and Buick Enclave. Outside of safety tech, it is also a partner with Ford on the adaptive steering system available on the upcoming 2015 Edge. These long-lasting partnerships make change difficult now that there's a problem. According to Reuters, automakers claim it would take a year or longer to set up with a different supplier for replacement airbag inflators. Switching to a completely different part for the repairs might not be a viable option either, because of the engineering time needed. BMW is taking action, though. According to Reuters, the Bavarian brand is working with the supplier to move inflator production from Monclova, Mexico, to a Takata factory in Freiburg, Germany. The Mexican plant may be the source of some of the faulty parts. News Source: Bloomberg, ReutersImage Credit: Jens Meyer / AP Photo BMW Ford GM Safety Takata airbag recall

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.
