Kapag ang makina ay umaandar, ang piston head ay nagkakaroon ng napakabilis na paggalaw. Sa mataas na RPM (revolutions per minute), ang piston head ay maaaring mag-ubos ng 1000 na kilusan sa isang minuto. Dahil dito, ang piston head ay dapat na matibay at makatiis sa matinding init at pressure. Ang mga materyal na ginagamit sa paggawa nito ay dinisenyo upang maging matibay at makatiis sa wear and tear.

The crankshaft is responsible for converting the linear motion of the pistons into rotary motion, which ultimately drives the vehicle. As the pistons move up and down, they push the crankshaft, which rotates and transfers this motion to the transmission and ultimately to the wheels. The crankshaft's design is critical, as it must balance strength and weight to handle the high forces during operation.
