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.

2014 Ford Fiesta gets fuel economy bump to 41 mpg

The 2014 Ford Fiesta is in showrooms now with refreshed styling and new performance ST model, but it's what isn't yet available that should help the Fiesta stand out from the growing crowd of subcompacts. Aside from the new 1.0-liter EcoBoost model coming later this year, Ford recently told us that a new Fiesta SFE trim level is on the way that should put the updated Fiesta at the top of its class for fuel economy.
The new Fiesta SFE will hit an estimated 41 miles per gallon on the highway when equipped with the six-speed automatic transmission. The current listing on fueleconomy.gov shows the 2014 Fiesta getting up to 29 mpg city and 39 highway, but the SFE will get minor aero tuning and a recalibrated engine controller to help bump the highway figure past rivals like the Chevrolet Sonic and Nissan Versa - both of which top out at 40-mpg highway. There's still no word as to when the small 1.0-liter EcoBoost will show in the US, but Ford has indicated that engine's fuel economy isn't expected to be released until October.

Kawei K1 pickup blatantly copies Ford F-150

The Chinese auto industry used to be looked at as a joke full of products blatantly copied from foreign vehicles. However, companies like Qoros and others show that the country's automakers have taken big steps in terms of original design. It doesn't look like every automaker there is ready to put down the tracing paper yet, though. Case in point: The Kawei K1 pickup pictured above, which is an obvious rip-off of the Ford F-150. In fact, the company isn't even hiding it. Kawei deserves a little credit for its openness. In describing the new model, it says: "No matter the black net grille and the outline of the headlamp, even if the styles of fog lamp and engine cover, it looks the same as Ford Raptor." It also admits that spelling out the model name on the hood is inspired by Land Rover. It's available with either a 2.4-liter, gasoline-fueled four-cylinder producing 141 horsepower and 148 pound-feet of torque (elsewhere it also lists it as having 162 lb-ft) or a 3.2-liter six-cylinder diesel with 106 hp and 181 lb-ft. Regardless of engine, power is sent to the rear wheels through a five-speed manual gearbox. The trucks cost around 100,000 Yuan ($16,033). So at least the K1 is a reasonably priced knockoff. According to Car News China, the K1 is actually selling in small numbers. The company made 10,000 of them last year and even exported some to Africa and the Middle East. Kawei's factory is doubling in capacity this year to build even more. You can read more about the truck on the company's website in some very mangled English.
