Fuel-injection System That Delivers 64 Miles Per Gallon

(PhysOrg.com) -- The best hybrid cars of today can only deliver about 48 miles per gallon. By using this newly developed fuel injection system a test vehicle was measured at achieving 64 miles per gallon in highway driving. ...

Amazing engines promise 60 to 100 mpg

It would be a mistake to count out the internal-combustion engine as yesterday's technology, soon to expire in a puff of exhaust gas. Electrification is coming, but meanwhile engineers have offered more innovation for the ...

Beaming rockets into space

Space launches have evoked the same image for decades: bright orange flames exploding beneath a rocket as it lifts, hovers and takes off into the sky. But an alternative propulsion system proposed by some researchers could ...

Volcanic ash affects airplanes, weather, sunsets

(AP) -- In 1989, all four engines of a Boeing 747 over Alaska conked out after it flew into a cloud of volcanic ash. The crew was able to restart them, but incidents like that dramatize why hundreds of flights every year ...

New sensor could prolong the lifespan of high-temperature engines

A temperature sensor developed by researchers at the University of Cambridge could improve the efficiency, control and safety of high-temperature engines. The sensor minimises drift –degradation of the sensor which results ...

First J-2X combustion stability test a success

(PhysOrg.com) -- NASA conducted a key stability test firing of the J-2X rocket engine Dec. 1, marking another step forward in development of the upper-stage engine that will carry humans farther into space than ever before. ...

Reducing fuel consumption of truck engines

A new model to explore how new ideas affect fuel consumption in large diesel engines has been developed by a world-leading research group in tribology, at Luleå University of Technology. Tribology is the science of interacting ...
