What are the benefits of dual VVT-i

VVT-i performs variable valve control in one direction.

Dual VVT-i controls the intake system and exhaust system of the engine respectively. When accelerating rapidly, VVT-i controls the intake time in advance and improves the valve lift, while VVT-i controls the exhaust time, just like a small turbocharger, which can effectively improve the engine power. Due to the increase of air intake, gasoline burns more fully, achieving the goal of low emission.
