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 125,000 Maverick, Escape, Corsair hybrids over fire risk

Ford is recalling more than 125,000 Maverick, Escape and Lincoln Corsair hybrids produced for the 2020-2023 model years to address a fire risk associated with failure of their internal combustion engines, which Ford says is happening with undue frequency. In the event of an engine block breach, oil and fuel vapors may collect under hood in places that would make them prone to ignition, meaning that an engine failure can do more than leave owners stranded.  "Isolated engine manufacturing issues have resulted in 2.5L HEV/PHEV engine failures involving engine block or oil pan breach," Ford said in its defect report to NHTSA. "In the event of an engine block or oil pan breach, the HEV/PHEV system continues to propel the vehicle allowing the customer to continue to drive the vehicle. As the customer continues to drive after a block breach, oil and/or fuel vapor continues to be expelled and accumulates near ignition sources, primarily expected to be the exhaust system." Per Ford, the "manufacturing issues" include poor machining of the engine crankshaft and contamination of engine block mating surfaces during assembly. The issue has been fixed in production, but 2.5-liter engines that escaped the factory with defects could be ticking time bombs. Ford's solution is to re-work the underhood components that allow combustible liquids and vapors near ignition sources. This way, the cars are better protected against immolation regardless of the circumstances. Signs of failure will be obvious, Ford says. Loud clanging or booming noises, a loss of power and smoke are all immediate signs that the customer should exit the roadway as safely and quickly as possible and shut the car down.  Owners should expect to receive notifications by the end of June or early July. They should begin circulating by mid-month. All remediation will be handled for the customer free of charge by their Ford dealerships.  Related video: This content is hosted by a third party.

2013 Ford Fusion Hybrid

Your Mileage May Vary
As difficult as it is to write this, I was actually excited about the 2013 Ford Fusion Hybrid. With the beautiful looks of the newest midsize fighter from Ford and a fuel economy estimate capable of shaming even the stalwart Camry Hybrid, the battery-augmented four-door seemed like a recipe for unabashed success. But appearances love nothing more than swapping our boundless enthusiasm for cold platters of disappointment. The 2013 Fusion Hybrid gets hobbled right out of the gate with a lofty price tag, and real-world driving keeps the sedan from even approaching those EPA figures.
With so many excellent midsize hybrids on the market, is there any reason to consider the newest Fusion Hybrid? Are sharp aesthetics, a well-executed interior and capable driving dynamics enough to overcome the machine's shortfalls? Not from where I'm standing.
