German Engineers Develop Diesel Engine With Barely Detectable Emissions
Engineers from the Technische Universitaet Munchen (TUM) have shown an engine prototype whose emissions are very close to the Euro 6 standard, even though the Euro 5 norm has just been put into force three months ago for all new car models.
A New "Open Rotor" Jet Engine That Could Reduce Fuel Consumption
NASA and GE Aviation are testing a new "open rotor" jet engine with a different design that puts the fan blades on the outside...

“Active Air Control” Improves Emissions and Fuel Economy in Larger Engines
An internal combustion engine (ICE) is essentially an air pump. The more efficient the air flows through the air pump (ICE), the better power...
New Engine Prototype That Mixes Gasoline and Diesel Gets 55 Percent Efficient
Researchers from the University of Wisconsin-Madison have recently unveiled a concept engine that can be from 20 to 30 percent more fuel-efficient than classic models. It would also be substantially cheaper to produce, since the emissions are lower than those of conventional engines and expensive catalyst units are not needed any longer (in some cases, their price can reach that of the engine's).
