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 issues recalls for Fiesta, Fusion, E-Series, and Lincoln MKZ

Ford has issued two new safety recalls for North America. The first covers certain 2014-15 Ford Fiestas, 2014-16 Ford Fusions, and 2014-16 Lincoln MKZs with doors that might not close properly. The second pertains to 2021 Ford E-Series stripped chassis and cutaway vehicles with a wiring harness that might chaffe and expose important wiring.    Ford is recalling 268,343 Fiesta hatchbacks, Fusion sedans, and MKZ sedans across the United States, Canada, and Mexico, with 248,912 of the affected vehicles located in the U.S. The recall says the "latch pawl spring-tab design" could crack in locations where the temperature gets too hot. If the tab breaks, the door might not shut. Or, worse, the door will shut temporarily and reopen once the vehicle is in motion. As a fix, Ford dealers will remove and replace the side door latches. In a separate recall, Ford is targeting 3,631 2021 E-Series stripped chassis and cutaway vehicles. These vehicles could have frame-mounted wiring harnesses that could deteriorate and break due to rubbing on the frame. If the chaffing wears down the harness, wiring for the fuel, trailer tow, and antilock braking systems could be exposed and damaged. In the worst-case scenario, the damage to the fuel pump wiring could cause the pump to stop working, which could stall the vehicle.  Those with affected E-Series vehicles should bring them in to dealerships for inspection. If there is no damage, technicians will add anti-abrasion tape over the area and "ensure clearance to surrounding components." If the harness is damaged, the wiring will be spliced and fixed, then anti-abrasion tape will be added. Ford also issued a third recall, but it is specifically for the Canadian market. On 54,292 examples of 2006-10 Ford Fusions, 2006-10 Mercury Milans, and 2006-10 Lincoln MKZs, a valve inside the hydraulic control unit might stick open. According to Ford, this could result in a longer brake pedal travel, which could possibly create dangerous situations if the driver is unaware. Dealerships will inspect the control units and replace those that are defective. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Ford looks to space robots to improve car-to-car communications [w/video]

Ford has partnered with St. Petersburg Polytechnic University for three years to research various kinds of connected vehicle communications. The university tie-up is part of its study of space robots, NASA systems created to enable space-to-Earth communication, and the university's own development of systems that enable communication between the International Space State and Earth.
The objective is for Ford to engineer layers of robust networks and redundancy systems that will allow your car to speak to other cars, to emergency vehicles, to infrastructure like traffic lights and buildings, and to the cloud. Benefits would come in just about every area of transit, from avoiding accidents, to getting medical workers to an accident more quickly, to improving the flow of traffic during rush hour.
Check out the press release below for details on what Ford wants to learn from the JUSTIN Humanoid and NASA Robonaut R2, and a video of technical leader Oleg Gusikhin discussing his interest in the project.
