In this helpful and informative webisode of Engineering Explained we find out if four valves per cylinder are better than two valves per cylinder! Ultimately we discover that four is much better because 4 valves per cylinder allows for more airflow than 2 valves per cylinder because there isa larger open area when the valves are open. Having a configuration with DOHC and four valves per cylinder means better airflow, especially at high engine speeds, resulting in better top end power. to learn in full depth click below!
