Piston Damage Infographic


The piston moves up and down inside your vehicle's engine cylinder through various stages of the combustion cycle. Driven by the engine's crankshaft and is connected to it via a connecting rod. When the piston moves down, the air and fuel are drawn inside the cylinder and when it moves up, it compresses the air-fuel mixture. It is also responsible for creating a vacuum or an area of low pressure inside the cylinder. The air pressure inside the cylinder is lower than the air pressure outside the cylinder.


A piston ring encircles the piston and acts as a seal between the combustion chamber and the crankcase. It is also responsible for driving the heat away from the piston to the cylinder wall and regulating the oil consumption. The piston skirt is the part of the piston that is closest to the crankshaft and keeps the piston from rocking inside the cylinder excessively.


There are many ways by which a piston can be damaged. The list below can help you determine the issue that is present in your motor:


1) The pistons can be damaged by issues in the head as well as due to piston pin seizing and piston pin fractures.
