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, ...

The rotary's reliability problem was mostly an owner problem. Here's the disciplined playbook that keeps FC 13Bs alive.

A Wankel engine is a type of rotary engine, but not all rotary engines are Wankel engines. Wrapping your mind around this idea will help you to better understand the similarities as well as the ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

Not every engine has a set of pistons that move up and down in a cylinder. The Wankel, or rotary engine, delivers its power with rotational force rather than a reciprocating mass that hammers out ...

The traditional piston engine has garnered the vast majority of attention and application in the internal combustion age, but there was another: the Wankel rotary engine. German engineer Felix Wankel ...

Alina has been enthusiastic about vehicles her entire life, and even from an early age found herself itching to get behind the wheel. Through high school and college, she could be found reading ...

How the 13B-MSP Renesis evolved from earlier Mazda rotary designs, technical features explained, and common problems and maintenance issues discussed. The 13B-MSP Renesis rotary engine powered the ...

Car enthusiasts generally have a love-hate relationship with the Mazda RX-8. It comes with buckets of personality and a unique powertrain. However, it’s also infamous for poor reliability and repair ...

It is quite ironic that internal combustion engines (ICEs) have remained basically the same for more than one hundred years. It is only now – when they are allegedly on the verge of disappearing – ...

It’s been over a decade since Mazda showed off a hydrogen rotary engine, but the lessons in engineering linger to this day. When it comes to engines, the Wankel rotary is one of the lightest and ...
