Variable cycle engine design embodies a transformative approach in aero‐propulsion, enabling engines to adapt their thermodynamic cycle to meet diverse operational demands, from fuel efficiency to ...

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 ...

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 ...

Imagine triangles spinning around a shower curtain rod inside a beer keg—that is an elemental description of the screaming Wankel rotary engine. This powerplant is beloved by gearheads the world over ...

GE Aviation has completed the detailed design process of its XA100 engine under the U.S. Air Force’s Adaptive Engine Transition Program (AETP), the company announced Thursday. The latest development ...

Most modern gasoline and diesel-powered engines found in the cars and trucks seen on today's roadways rely on the four-cycle-engine principles developed in the late 1800s by Nikolaus Otto, Gottlieb ...

Rolls-Royce Holdings PLC’s German division is equipping some of its aerospace design engineers with artificial intelligence tools in an effort to speed up the yearslong process of designing and ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...

The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines ...

Since it is essential to design an aircraft engine nozzle to achieve IR signature suppression, an S-shaped nozzle (double serpentine nozzle) is applied so that the high temperature part of the engine ...

The internal combustion engine, despite being a century-and-a-half old, is still an impressive marvel of engineering. There are several variations of engine design that have been experimented with ...
