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 Transit gets outfitted for prison duty

Between the Taurus-based Police Interceptor, the Explorer-based Police Interceptor Utility and the F-150 and Expedition special service vehicles, Ford has no lack of offerings for law enforcement. And now it has one more in the form of the new Transit PTV.
Based on the fullsize Transit van, the Prisoner Transport Vehicle can move as many as 12 prisoners in three separate compartments between detention facilities. Created in collaboration with Pennsylvania-based Havis Prisoner Transport Solutions and with input from Ford's Police Advisory Board, the Transit PTV takes advantage of the Transit's considerable configuration options that include three roof heights, two wheelbases, three lengths and four body-styles - not to mention engine options that include the flex-fuel 3.7-liter V6, 3.5-liter EcoBoost and 3.2-liter Power Stroke diesel.
"Transit PTV is the latest example of Ford's deep commitment to helping provide law enforcement agencies with capable vehicles. This concept proves Transit is upfit-ready and designed to Built Ford Tough standards," said Jonathan Honeycutt, Ford police marketing manager. "Many Police Advisory Board members have had the chance to drive this vehicle and they are excited about it. This new vehicle is tough, smart and efficient - ideal for the needs of law enforcement agencies."

Ford recalls 650,000 trucks and SUVs for defective wipers

Ford announced earlier this month that it is recalling 652,996 F-Series pickups, Expeditions and Lincoln Navigators produced for the 2020 and 2021 model years to address an issue that may cause their windshield wipers to separate, reducing visibility and leading to potentially hazardous driving conditions.  According to the Blue Oval, one of its suppliers used worn tooling components that resulted in wiper arms being produced with splines that are not tall enough to fully engage the motor pivots they're mounted to, which can cause the connection to strip when the motors are turned on. This could result in the wiper arms not moving at all, or engaging only intermittently.  "Worn wiper arm spline tooling core inserts at the supplier resulted in insufficient spline tooth height, which can cause the arm attachment to strip when used with a certain wiper motors with higher torque," Ford said in its defect report to NHTSA. "Potential symptoms include erratic or slow wipe speed of the driver or passenger wiper arm. An improper functioning wiper arm may potentially result in reduced visibility in certain conditions, which could increase the risk of a crash." Ford says the vehicles were not produced in VIN order, so while not all of the nearly 653,000 vehicles have bad wiper arms, they're all suspect until proven safe. Ford will notify owners of the recall campaign starting in May.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
