Whether we're talking about vehicles with two or four wheels, a primary goal of engineers is to wring out as much power from each unit of displacement for every engine they make. This keeps weight ...

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 ...

While there have been some iconic big-block engines over the last few decades, it's difficult to argue with the success of the small-block engine. Small-block engines not only weigh less — allowing ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

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 ...

Just about every piston engine is defined by two basic measurements: bore and stroke. Bore is the diameter of the cylinder. Stroke is the distance the piston travels from bottom dead center to top ...
