what is expansion ratio in ic engine

what is expansion ratio in ic engine The base of a reciprocating internal combustion engine is the engine block which is typically made of cast iron due to its good wear resistance and low cost or aluminum In the latter case the cylinder liners are made of cast iron or steel or a coating such as nikasil or alusil The engine block contains the cylinders In engines with more than one cylinder they are usually arranged either in 1 row
