Pop the hood on a classic Mazda RX-7 or RX-8 and the engine bay looks oddly empty. That is the charm of the rotary engine: a compact lump of metal that trades pistons and valves for a spinning ...

Perfectly tuning the heat range of an engine's spark plugs is something of a dark art to all but the most well versed tuners and the engineering egg heads at automotive OEMs. Getting the spark plug ...

There are many different forms of internal combustion engines, but most use the same basic principle. Explosions in the combustion chamber move pistons up and down to spin a crankshaft. That ...

Rotary engines, known for their unique design and compact size, have been predominantly associated with Mazda. However, engineers and automotive enthusiasts have experimented with incorporating these ...

Over-the-top rotary builds are an enthusiast tradition. Because so few rotary cars have been made, the limits of the engine type haven't been fully exploited by automakers. It's been tuners who have ...

Professor Aniebiet Inyang Ntui is a multi-faceted individual whose expertise spans the worlds of library and information science, environmental advocacy, and – perhaps surprisingly – the automotive ...

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 ...

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 was the most radical rethink of the combustion engine in over a hundred years — and it paid the price for being different. Mazda introduced the innovative Wankel rotary engine in the 1967 ...

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 ...

Good news, everyone! Mazda is not only reassembling a dedicated team of engineers for rotary engine development, as we’ve reported earlier, but today it also announced its intention to expedite ...
