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

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

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

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 ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

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 ...

Achates Power’s cleaner, heavy-duty diesel engine it developed in a project funded by the California Air Resources Board and several partners has entered fleet service with Walmart in a Peterbilt 579 ...

Cylinder wall scoring can be caused by a lack of oil or oil contamination. It can be prevented through careful maintenance ...

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 ...

Most of us consider piston rings little more than a necessary evil. That's probably because grinding rings is a time-consuming chore. And who hasn't accidently ground a gap too large and wasted both ...
