Wankel rotary engines, typically but not exclusively found in Mazdas, certainly lean on the "quirkier" side of modern powertrain systems, made quirkier because most rotary-powered cars on the road ...

While modern engines feature many tweaks and improvements on the original ideas, they usually aren't as interesting as the strange contraptions engineers experimented with in the early days. Take, for ...

Aircraft piston engine cylinders are a common point of failure, susceptible to issues like cracks, valve malfunctions, and head/barrel separation. Excessive heat is the primary cause of cylinder ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...

Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal combustion engines developed over the course of more than century.
