4-Cylinder crankshaft assembly

### Key Components: - **Pistons**: Convert expanding gas force into mechanical motion. - **Connecting Rods**: Link pistons to the crankshaft, transforming linear motion into rotation. - **Crankshaft**: Central component that converts piston movement into rotational motion, balanced by counterweights. - **Flywheel Flange**: Positioned on one end of the crankshaft for mounting a flywheel, ensuring smooth engine operation. ### Design Focus: - **Balance and Smooth Operation**: The crankshaft and counterweights are designed for minimal vibration. - **Strength and Durability**: Components are robust to withstand high forces during engine operation. - **Precision**: Ensures proper fit and efficient performance
