This is a detailed 4-cylinder (I4) internal combustion engine model designed in Autodesk Fusion 360. The assembly features a fully operational crankshaft, connecting rods, and pistons, demonstrating the core mechanical principles of a standard automotive engine.

Mechanical Accuracy: Designed with precise constraints to ensure smooth rotation.

Motion Study: Included joints allow you to rotate the crankshaft and observe the 1-3-4-2 (or preferred) firing order movement.

Purpose: Great for educational purposes, 3D printing, or as a base for more complex RC projects.
