Jacobs Vehicle Systems - Technology

EVOLVE+ is the next step in valve motion flexibility. The system enables better control of HCCI combustion through variable valve timing control. With EVOLVE+, you determine the strategy for implementing specific engine operating and performance enhancements, such as improved startability and integrated engine braking.

As you move beyond 2012, our VVA platform evolves with you to meet new emissions standards. The benefits are considerable: integrated engine braking that delivers convincing retarding power and endless options for balancing trade-offs between fuel economy and emissions. It all starts with the most powerful engine brake ever developed.
