Gasoline and diesel versions of an internal-combustion engine that promises 60% fuel efficiency and an 80% reduction in emissions are being built in preparation for demonstration next year. The ...

Two years ago it was only a well-developed concept. (See “Rethinking engines,” MACHINE DESIGN, March 3, 2007). But this year, the Scuderi Group unveiled a cutaway model of the proof-of-concept ...

DETROIT -- In the back aisles of the Society of Automotive Engineers convention recently, past the displays hawking springs and sprockets, one family's dream began to take shape. Scuderi Group of West ...

Rocket engines and the internal-combustion cycle get a remake, thanks to engineering ingenuity. When it comes to engines, smaller and more powerful are always better. Throw in less expensive and ...

Even as EVs begin to encroach on ICE cars, the development of fuel-burning engines hasn't stopped. With almost 150 years of development in the Otto cycle internal combustion engine, you may think ...

With a slogan like “The Future is Ecclectic,” we’d expect some interesting things from INNengine, a startup based in Spain. The company is showcasing a “one-stroke” engine that works as an opposed ...

The Scuderi split-cycle engine design — billed as the world’s most fuel-efficient engine design — was recently analyzed at the Southwest Research Institute. The independent lab’s study predicts the ...

Two-stroke engines have steadily fallen out of favor over the last 50 years or so. While they sport great power-to-weight ratios and are often much simpler mechanically than their four-stroke ...

A piston aircraft engine that recaptures energy during deceleration and landing and uses it for supercharging during take-off and cruise, reducing fuel consumption and emissions, has been patented by ...

Porsche was issued a patent for its six-stroke combustion engine on October 22, 2024. The company describes the new engine as having a "working cycle" of three complete crankshaft revolutions with two ...

Electric vehicles and plug-in hybrids are in the headlines at the moment, but the traditional internal combustion engine isn’t about to burn its last, writes Farah Alkhalisi. We talk to four ...
