Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need valves to ...

Four-stroke engines, which make up 99% of vehicles on the road, rely on a system for managing air intake, compression, ...

Here's the process of making this rotary valve engine with a different intake and an exhaust system. It wasn't easy to start this engine and took some time to fully complete it. #shorts #diy #asmr #re ...

That alone reduces emissions and increases engine longevity. The rotary valve also means that the blockages caused by conventional poppet valves are not an issue as poppet valves are not needed in ...

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 ...

Researchers at Purdue University's College of Engineering are conducting tests on a patented Tesla valve-inspired injection manifold design to improve the efficiency of rotating detonation engines ...

The piston engine may be the most common type of internal combustion engine found in consumer automotive vehicles. That doesn't mean it's the only option drivers have ever had access to. In the 1960s, ...
