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, Samsung shack up to bring regen braking to non-hybrid models [w/video]

Ford must be desperate to get itself ready for the beach this summer because it is really trying to get into shape. Shortly after unveiling the Lightweight Concept that cut the weight of a Fusion down to that of a Fiesta, it's now the rest of the line's turn for improvement. The company is wrapping up a 10-year research project aimed at developing next-gen automotive batteries to improve efficiency.
Ford claims that 70 percent of its lineup will have stop/start tech by 2017. The key to this massive proliferation is its new dual-battery system that combines a lithium-ion battery with a lead-acid one and regenerative braking. The setup works by harvesting braking energy and converting it to electricity. When the vehicle stops, the engine shuts off, but the Li-ion battery has enough juice to keep the accessories running. The engine starts up again as drivers take their foot off the brake. The layout would mean less wasted gas while idling. It's already available on Ford hybrids and is somewhat similar to the i-Eloop capacitor-based system from Mazda.
The bigger challenge is tuning the regenerative braking right. While hybrid drivers may be a little more adventurous, when it comes to getting a hang of regen braking, conventional buyers might not be so open-minded. The systems have a tendency to be a little grabby at first and then taper off at very low speeds. Ford needs to make sure it's just right to avoid turning off buyers.

Major automakers post mixed US June sales figures

General Motors, Ford and Fiat Chrysler Automobiles NV posted declines in US new vehicle sales for June on Monday, while major Japanese automakers reported stronger figures. Once again, demand for pickup trucks and crossovers offset a decline in sedan sales. Automakers' shares rose as overall industry sales still came in above Wall Street expectations. The US auto industry is bracing for a downturn after hitting a record 17.55 million new vehicles sold in 2016. Analysts had predicted that overall, US vehicle sales would fall in June for the fourth consecutive month. As the market has shown signs of cooling, automakers have hiked discounts and loosened lending terms. Car shopping website Edmunds said on Monday the average length of a car loan reached an all-time high of 69.3 months in June. "It's financially risky, leaving borrowers exposed to being upside down on their vehicles for a large chunk of their loans," said Jessica Caldwell, Edmunds' executive director of industry analysis. GM said its sales fell about 5 percent versus June 2016, but that the industry would see stronger sales in the second half of 2017 versus the first half. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." GM shares were up 2.4 percent in morning trading, while Ford rose 3.3 percent and FCA shares jumped 6 percent. "US total sales are moderating due to an industry-wide pullback in daily rental sales, but key US economic fundamentals clearly remain positive," said GM chief economist Mustafa Mohatarem. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." Ford said its sales for June were hit by lower fleet sales to rental agencies, businesses, and government entities, which fell 13.9 percent, while sales to consumers were flat. But it sold a record 406,464 SUVs in the first half of the year, with Explorer sales increasing 23 percent in June. And sales of the F-150 had their strongest June since 2001. On a media call, Ford executives said an initial read of automakers' sales figures indicated a seasonally adjusted annualized rate of around 17 million new vehicles for the month, which would be better than 16.6 million units analysts had predicted. FCA said June sales decreased 7 percent versus the same month a year earlier.
