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

Here you can see basic piston terminology, including major and minor thrust locations. Of particular note is the fact that piston pin offset can be used to counteract combustion pressures on the ...

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 ...
