We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

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 ...

Modern piston engines are incorporating advancements such as fuel injection, turbocharging, and electronic controls (like Lycoming's iE2 system). Weight reduction is a key focus; engines like the ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

An opposed-piston engine packages two pistons in each cylinder and produces more power density than a conventional single-piston-per-cylinder engine.ACHATES POWER / TNS While Tesla, General Motors, ...

Most of the internal combustion piston engines built for vehicles throughout history have pretty familiar core designs. The majority of fuel-burning vehicles sold today orient their pistons in inline ...

The opposed-piston engine has been around for over 100 years and is more efficient in almost every way. The engine has no traditional valves, cams, or camshafts, and no head, so it’s simpler and ...
