Variable Valve Timing System

The variable valve timing system adjusts the opening and closing time of the intake valves depending on engine temperature, speed, and load. This controls nitrogen oxide (NOx) formation and provides optimal performance and economy while minimizing the exhaust emissions. To further enhance fuel economy, some variable valve systems actually shut off some of the intake valves during highway cruise conditions.
