Design Challenges
One of the biggest challenges was ensuring proper synchronization between the camshaft and the crankshaft. This required fine-tuning the positioning of the timing gears and belts to ensure that each piston fires at the right moment. Additionally, the layout of the intake and exhaust manifolds needed careful design to allow efficient airflow across all cylinders.
