PISTON EXPANSION


Meaning of PISTON EXPANSION in English

Because pistons are usually made of aluminum and the cylinder walls are made of iron, the piston will expand more rapidly than the cylinder when they get hot. Some type of compensation needs to be made for this expansion or the piston will seize in the cylinder. Also see split skirt , T-slot , steel strut , and cam-ground piston .
