1. Gear Drive: This method uses a set of gears to connect the crankshaft and camshaft. It is the most common type of camshaft drive and offers precise timing control. However, it can be noisy and requires regular maintenance.
2. Chain Drive: A chain drive uses a chain to connect the crankshaft and camshaft. It is quieter and more durable than a gear drive but can stretch over time, requiring periodic adjustment or replacement.
3. Belt Drive: A belt drive uses a toothed belt to connect the crankshaft and camshaft. It is the quietest and most maintenance-free option but is less durable and can slip if not properly tensioned.
