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 Explorer and Lincoln MKC for fire hazard

The Basics: Ford will recall 5,536 examples of the 2016 Explorer and 2015-2016 Lincoln MKC. The Explorers have build dates between October 20, 2014, and January 28, 2016, at the Chicago Assembly Plant. The MKCs are from between November 25, 2013, and January 25, 2016, at the Louisville Assembly Plant. In total, there are 3,129 total affected examples of the 2015-2016 Lincoln MKC and 2,407 examples of the 2016 Ford Explorer. Of these, 1,543 are in the US and 3,993 are in Canada. The Problem: The combination of the engine block design and the block heater in these vehicles can cause the part to overheat when plugged in. Injuries/Deaths: None reported, but there are two cases of underhood fires in Canada. If you own one: Ford will begin notifying owners during the week of May 16, company spokesperson John Cangany tells Autoblog. Related Video: Ford issues safety recall for certain 2015-2016 Lincoln MKC and 2016 Ford Explorer vehicles to replace engine block heaters Ford is issuing a safety recall for approximately 5,500 2015-2016 Lincoln MKC and 2016 Ford Explorer vehicles to remove the heaters and replace them with an updated design. The engine block design, coupled with the particular block heater installed in these vehicles, causes the unit to be susceptible to overheating when the vehicle is parked and the block heater is plugged in –increasing the risk of an underhood fire. Ford is aware of two reports of underhood fires in Canada, but is not aware of any accidents or injuries related to this issue. Affected vehicles include certain 2015-2016 Lincoln MKC vehicles built at Louisville Assembly Plant, Nov. 25, 2013 through Jan. 25, 2016 and certain 2016 Ford Explorer vehicles built at Chicago Assembly Plant, Oct. 20, 2014 through Jan. 28, 2016. There are 5,536 vehicles affected by the issue, including 3,129 2015-2016 Lincoln MKC and 2,407 2016 Ford Explorer vehicles, with 1,543 of the affected vehicles in the United States and federalized territories and 3,993 in Canada. Dealers will remove and replace the engine block heater with an updated design and, if needed, replace the cord at no cost to the customer.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.
