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 ...

Mazda’s implementation of the Miller-cycle engine in their production vehicles, starting with the 1995 Xedos 9, marked a significant shift in automotive powertrain design. The unique 2.25-litre V6 ...

The term Atkinson cycle goes around a lot when talking about automotive engines. What does it mean? When did cars start using these engines?

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

When I went to school for engine repair in the 1980s, we studied the differences between two- and four-stroke engine cycles extensively. If you're not familiar with engine strokes, understanding the ...

Details of the operating cycles of the new-generation adaptive engines remain sparse, but the key difference between the GE XA100/P&W XA101 and earlier variable-cycle concepts such as GE’s XF120 from ...
