Prof. Rolf Reitz (center) and members of his student team with the RCCI-powered Saturn

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

The new Volvo XC90's hybrid drivetrain

We've seen the interior of the new Volvo XC90, and we have an idea of its shape, but until now there has been no word on what would be under the hood. Volvo has now released details of the engines that will power its new SUV.  Read More

Mercedes is slowly teasing the details of its new AMG GT

Mercedes has taken the slow approach to revealing its new AMG GT supercar. We've seen the interior and some hazy shots of its profile, but until now we didn't know anything about how it would perform. So what's under the hood?  Read More

The Hazumi concept points towards the new Mazda 2, which will be the first car to feature ...

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

The Hondajet has passed another milestone on its way to entering commercial service. After completing FAA certification testing last year, the executive jet's first pair of production HF120 jet engines have been shipped.  Read More

The first Trent XWB moving from the factory floor

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

The new coating protects airplane engine components from heat damage, while lasting 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.  Read More

At the microscopic level, combustion can't support itself, as it does in this Petri dish f...

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.  Read More

The DIG-T-R weighs 40 kg (88 lb), yet puts out 400 bhp

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.  Read More

Test firing of the BE-3 hydrogen/oxygen rocket engine that took place on Nov. 20, 2013 (Ph...

NASA announced on Tuesday that Blue Origin had successfully test fired its new BE-3 hydrogen/oxygen rocket engine at the company’s West Texas facility in Van Horn. The test, which took place on November 20, was a series of static firings to simulate the engine sequence of an actual suborbital flight from lift off to landing and is part of the development of Blue Origin’s manned Orbital Launch Vehicle for carrying passengers and cargo into low Earth orbit.  Read More
