Pistons are cylindrical components integral to an internal combustion engine’s reciprocating assembly. They convert expanding gas pressure from combustion into linear motion via a connecting rod and crankshaft. Typically constructed from aluminum alloys for weight reduction and heat dissipation, pistons feature precision-machined ring grooves to house compression and oil control rings. Crown designs vary to optimize combustion chamber geometry and promote efficient flame propagation. Skirt profiles are engineered to minimize friction and maintain stable operation within the cylinder bore.
