Nissan introduces innovative valve control technology

Tokyo, Japan – The Nissan Motor Company has introduced a new engine technology that it says delivers a balance of responsiveness and power, fuel efficiency and low emissions. The new system combines the technologies behind Nissan’s newly-developed Variable Valve Event and Lift (VVEL) and continuous valve timing control (C-VTC) to deliver significantly enhanced performance. The technology will be available to customers worldwide through the Nissan and Infiniti product lines.

The first product to feature the VVEL technology is the Infiniti G37 coupe, scheduled to be unveiled at the New York Auto Show in April.

While conventional engines control air intake using a throttle valve, VVEL-equipped engines do this directly at the intake valves, continuously controlling their valve events and lifts. C-VTC and VVEL together control the valve phases and its valve events and lifts, allowing free control of the valve timing and lift. This results in more efficient airflow through the cylinder and significantly improves responsiveness.
