Camshaft lift refers to the maximum height the valves are lifted off their seats when they open. Here's how camshaft lift affects engine operation:
1. **More lift**: Higher lift allows the valves to open wider, which increases the flow of air and fuel into the cylinders and makes it easier to evacuate exhaust gases. This can increase engine power and efficiency.
2. **Risk of collision**: Too much lift can, however, lead to risks of collision between the valves and the piston, especially if the engine is not designed for such configurations. It is therefore crucial to ensure that the lift is compatible with the engine design.
3. **Effect on Torque and Horsepower**: Increased lift can improve torque and horsepower at higher engine speeds. However, this can sometimes come at the expense of low-end performance, as excessive airflow at low speeds can disrupt combustion.
4. **Adjustments and Compatibility**: Changing lift often requires other adjustments, such as stronger valve springs, and must be compatible with other camshaft characteristics, such as cam duration and profile.
In summary, camshaft lift is a crucial factor in determining engine performance, influencing air and fuel flow as well as combustion efficiency. Higher lift generally favors high-rpm performance, but must be carefully balanced to avoid mechanical problems and ensure optimal engine operation.
