Jacobs Vehicle Systems - Technology

Integrate the 2010 VVA subsystem into your engine design for greater control over your overall emissions package with the capability to adjust valve motion, cycle-to-cycle and cylinder-to-cylinder. Since the Jacobs VVA system can select the best valve motion for each mode of operation, it can control exhaust gas temperature, increase low-end torque, reduce emissions, boost transient response and optimize fuel consumption.

While providing all of these benefits, VVA operates with a low-risk default-to-mechanical mode. The majority of the components are derived from existing systems proven by millions of miles of experience. Jacobs Evolve VVA only runs when you need it, giving you the freedom to determine the path to optimum performance.
