Mercedes introduces hi-tech pistons made from steel

In 1936, Mercedes-Benz became the first company in the world to launch a diesel passenger car – the 260D. Over the years, diesel automobiles became renowned for their efficiency and fuel economy. Now, the manufacturer is building on that success with the introduction of high-tech steel pistons.Read More

Experimental diesel/gas engine could give 2009 Saturn a big boost in fuel efficiency

Five years ago we first heard about a Caterpillar diesel engine located at the University of Wisconsin-Madison, that had been modified to run on an unlikely-sounding mixture of diesel and gasoline. Not only did the one-cylinder engine work, but it was more efficient than pure-diesel or pure-gas engines at converting the chemical energy of fuel into motion. Sitting in a basement lab, however, isn't the same as experiencing use in the real world. That's why students at UW-Madison, led by Prof. Rolf Reitz, have now put another diesel/gas engine into a 2009 Saturn. Read More

Mazda joins the downsizing party with 1.5-liter SKYACTIV diesel

In spite of the saying "ain't no replacement for displacement," manufacturers are making their engines smaller by the day. Ford has its 1.0-liter EcoBoost, and Mini a 1.5-liter three cylinder motor. Renault's next Twingo will feature not only a 1.0-liter engine, but a 900cc motor making 90hp. Now, Mazda has joined the global trend for downsizing engines with its new turbocharged 1.5-liter SKYACTIV diesel. After teasing us at the Geneva Motor Show, the Japanese car company has finally released details of its new motor. Read More

"World's most efficient aero engine" on its way to first A350 XWB

Last year, the Airbus A350 XWB took to the air for the first time. Eleven months later, Rolls-Royce announces that the first production Trent XWB turbofan engine that powers the plane has left the factory and is on its way to Toulouse, France to be installed in a Qatar Airways A350 XWB. According to Rolls-Royce, Qatar airways has ordered 80 of the aircraft and the “world's most efficient aero engine” engine is the first of 1,600 ordered worldwide by 40 airlines around the world.Read More

Nanoparticle coating could let aircraft engines last three times longer

The higher the temperature at which an aircraft engine is able to run, the more efficiently it uses fuel. In order to run at those high temperatures, the metal components of airplane engines are presently treated with heat-shielding coatings. Scientists at Sweden's University West, however, are developing a new such coating that is said to be far more effective than anything presently used – it could extend the service life of engines by 300 percent.

Researchers develop new microengine, but aren't sure how it works

If you’re going to do something like building a Porsche 911 that fits on the head of a pin, or make a microscopic medical pump, you need a microscopic engine. A team of researchers from the University of Twente in the Netherlands, the Russian Academy of Sciences, and Germany’s University of Freiburg have developed a micro-engine that burns oxygen and hydrogen, but there’s a small problem; they’re not sure how the thing works.

Nissan's new 400 bhp engine fits in carry-on luggage

It’s a common problem: You’re off to Le Mans with your new 400 bhp engine and you discover that it won’t fit in the airplane's overhead compartment. This week, Nissan showed off the answer to this traveler’s nightmare with its ultralight DIG-T R 1.5 liter, three-cylinder petrol engine that is small enough to fit in carry-on luggage and boasts a power-to-weight ratio better than the engine of a Formula 1 racer.
