A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

Ford Fiesta 1.0L EcoBoost sales robust in early going

Okay, okay, okay, so I was just a smidge wrong. Those that read my review of the Ford Fiesta with the new 1.0-liter, EcoBoost engine will know that while I really enjoyed the torquey little three-cylinder, I was concerned that Ford's decision to force 1.0-liter owners into a manual transmission, steel wheels and one trim level might hurt sales of the new engine. I was also concerned that the promised 45-mile-per-gallon highway rating wouldn't be enough to tempt buyers into trying an engine that's so far outside of what the general public is use to. My concerns, though, seem to have been for naught.
While not doing a booming business on the triple-equipped Fiesta, Ford is seeing a take rate of four to eight percent per month in the engine's first few months on sale. Now, four to eight percent might not sound like a lot - if, like last year, the Fiesta sells around 71,000 units, there'd be barely 5,600 1.0-liter models on the road. It is also small potatoes relative to the take rate on EcoBoost-equipped vehicles across the Ford range, which US sales analyst Erich Merkle estimates to be roughly 35 to 40 percent of retail sales. Still, according to The Detroit News, the 1.0-liter is getting adopted at roughly the same rate as the sparkling Fiesta ST, which should be a solid indication of just how well this little engine is doing.
The 1.0-liter's success "really speaks volumes, not just to what we're doing with the Fiesta, but with EcoBoost in general," Merkle told Autoblog.
