4-Stroke Engine

This is a detailed 3D assembly of a 4-stroke internal combustion engine modeled in SolidWorks. It includes key components such as pistons, connecting rods, crankshaft, and piston pins, all designed with proper mates to simulate real-world motion. The assembly is carefully constructed to reflect the working mechanism of a four-cylinder engine. This model can be used for educational animation, mechanical analysis, motion simulation, and manufacturing reference.
