A new research paper from Ford Motor Co. and Carnegie Mellon University says turbo cars are not the cause of fuel economy declines, but are a factor.
It’s the first time a study has been presented by automakers to the American Society of Civil Engineers.
The findings could be an important first step to fixing a problem with fuel economy that is hurting the economy in many parts of the country.
The new study found that the average turbo car is getting a little faster and that its fuel efficiency is increasing over time, with the average engine running at about 5.2 L/100 km.
That’s a significant improvement over the previous study that showed a 4.6-liter turbo engine was getting the best performance, but a 3.7-liter engine could get much worse performance.
The turbo cars have been around since the early 1990s, but the new study shows they were only getting a small improvement.
Ford says its new research helps the automakers understand the drivers behind the fuel economy gains.
“Fuel economy is a very complicated equation that depends on a number of factors, including the air speed, air pressure, temperature, humidity, road conditions and other factors,” said Ford senior vice president and general manager of global vehicle technologies and technology, Joe Hinrichs.
“So, we’re looking at some of these other factors to see how much they can make a difference.”
The study looked at the fuel efficiency of four different engines, including a turbocharged four-cylinder Ford Focus, a three-cyl, turbocharged Ford EcoBoost and a 3-liter Ford F-150 Raptor.
It found that turbo cars were getting a big improvement in fuel economy as the turbocharger efficiency rose.
In fact, the average fuel economy for a turbo engine rose from 3.1 L/1010 km in 1990 to 3.9 L/1,064 km in 2016.
Ford is calling this an 8.6 percent improvement over that year.
“It’s a big leap,” Hinrich said.
“That’s a huge improvement over a year ago.
It could mean that they’re getting closer to a car that’s getting 10 percent more fuel economy, so that’s a pretty big step in that direction.”
The fuel efficiency gains came from a variety of factors.
First, a smaller engine meant less turbochargers were needed, meaning they would get more power.
Second, the turbocharged engines were getting better at increasing the air pressure to get more air to the fuel tank.
“You might get some air pressure reduction,” Hinricks said.
Another big factor is that turbochargering reduces friction, which means more fuel can be taken out of the system.
Hinrich says the turbo engine that Ford tested in this study has the smallest friction in the history of the turbo and is about three times as fast as a conventional four-stroke engine.
“If you want to increase the fuel consumption, it’s going to be much more important than just changing the air system,” Hinricks said.
The study also found that turbos are getting a lot more power than other engines.
In the turbo cars, the fuel pressure is up to 2,700 psi and that is the highest pressure ever measured in a turbo car, said Ford researcher Brian Fuchs.
That makes it very difficult for the engine to run smoothly, which has some impact on performance.
“Turbo engines can run faster, but it’s a lot harder to get the same fuel efficiency,” Fuchs said.
A turbo engine has three cylinders.
There are two turbochargors, which are made from aluminum and are attached to a single crank.
They spin at about 4,000 rpm and are connected to the crankshaft by a series of connecting rods.
The crankshark is used to control the number of cylinders and the air flow.
There’s a variable valve timing system that can control the timing of the valves.
The air flow can be controlled by changing the ratio of the air entering the turbo to the air exiting the turbo.
It also has a variable air filter that is used by the engine in order to control exhaust gases.
The researchers say that it takes about 2,500 hp and 3,000 pounds of torque to drive a turbo, so the difference between an 8-liter and a 4-liter has to be pretty big to be noticeable.
The most important factor, according to the study, is the turbo’s fuel injection system.
That can change the amount of air that enters the engine and the amount that is left in the engine.
The paper says that the new technology has the potential to be a key part of the fuel cell in future electric vehicles.
“A new fuel injection design may provide significant benefits for the fuel system in future EVs,” said Hinrich.
The authors of the paper say that the study shows the benefits of a new technology to be significant.
“For a long time, it was a question of how
