Four cylinder engine

3D CAD model of a crankshaft and piston assembly, commonly found in internal combustion engines. It showcases the precise mechanical relationship between key components:

Pistons: Four cylindrical pistons, responsible for converting combustion energy into motion.

Connecting Rods: Golden-colored rods that link the pistons to the crankshaft, facilitating the conversion of linear motion into rotational motion.

Crankshaft: The central gray rotating shaft with offset crankpins, designed to transfer power generated by the pistons into rotational energy.

Flywheel/Flange: The circular component at the end of the crankshaft, which aids in reducing engine vibrations and ensuring smooth operation.
