Expansion of Piston Due To Heat

Expansion of Piston Due To Heat Points : Expansion of Piston Due To Heat For the duration of process the piston runs a lot of amount hotter than the cylinder, as the cylinder is surrounded through cooling water. Thus this piston increase more than the cylinder. This expansion has to be proscribed in order to evade loss of sufficient piston clearance. Such a loss might reason grave engine problem. Problem is extra precise with aluminum pistons as aluminum expands extra quickly than iron with the increase of hotness.
