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

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 ...

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

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

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 ...

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 ...

This is a preview. Log in through your library . Abstract An unique measurement method was developed for measurement of the piston outer surface during the engine operation. The method was realized by ...

You might overlook the end gaps of piston rings in your car. They shouldn't be taken so lightly, though, as they actually play a vital role in your engine.
