Answers: How does Hyundai's CVVD engine technology work?

• Continuously Variable Valve Duration
• CVVD engine technology
• valve timing and lift mechanics
• Hyundai Sonata 1.6L turbo engine
• camshaft and cam lobe linkages

What it concludes

• Hyundai's CVVD system allows mass-produced engines to continuously vary how long a valve remains open relative to engine speed.
• The CVVD system provides up to 5 percent better fuel economy, 4 percent better performance, and up to 12 percent reduced emissions.
• CVVD achieves greater flexibility and efficiency than fixed valve systems by altering rotational center via a mechanical linkage.
• Hyundai chose a purely mechanical system over alternatives like Freevalve due to cost, energy efficiency, and predictable mechanical failure modes.
