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 ...
The 1974 Mazda REPU was the world's only mass-produced rotary pickup truck, featuring a 1.3L Wankel engine with 110 hp and ...
Can a single rotor Miata exist without shaking itself apart? Can a single rotor Miata be even more fun to drive than its ...
Mazda made a splash in the market in 1990, launching the Eunos Cosmo with the three-rotor 20B engine. Compared with contemporary Wankel rotary engines, the 20B's extra rotor beefed the compact ...
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, ...
Record-breaking goal: Rob Dahm's 12-rotor engine aims to produce 5,000 HP, a figure rarely seen outside of drag racing or marine engines. Unique rotary design: The engine combines three four-rotor ...
Most vehicles use a piston engine similar to the one-cylinder, four-stroke motor in the first car ever made, Karl Benz's Patent Motorwagen. Lately, a more fuel-efficient and emissions-friendly engine ...
Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...
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 ...
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 ...
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 ...
