Dimpled pistons might sound strange, but some say they could be the future for diesel power. We've looked at the arguments ...

Piston-engined fighters ruled the roost for thirty years. A brutal survival of the fittest ensured a rapid evolution of these characterful machines; the final fighters were over six times faster and ...

The mind-bending world of birotary engines - a hybrid of piston and rotary technology that could revolutionize aviation. But ...

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

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 ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

Pistons are an engine-building element we like to brag about, but you won't catch many of us boasting about having cast pistons. Cast pistons are for wimps. Many of us like to talk up hypereutectic ...

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 ...

Piston ring end gaps matter more than you think because they manage pressure and heat, preventing catastrophic failures ...

Just because LEGO Technic is technically a toy doesn’t mean that you cannot do solid engineering with it, like building air-powered engines. After first building a simple air-powered piston ...

No experienced engine builder would intentionally bolt a cylinder head to an engine block without installing a gasket between the block and cylinder head. The gasket seals the block-deck surface to ...
