What is VVA and Why Do You Need it ?

All internal combustion engines use valves to control the flow of gasses into and out of the combustion chamber.  The precise timing, duration and extent to which these valves open significantly affects all aspects of engine performance - from power and torque to fuel economy and emissions.

With fixed valve events, it is impossible to optimise an engine's performance over the complete range of operating conditions without significant compromise.   Variable Valve Actuation removes this constraint by allowing us to change the valve event to give optimum performance whenever it is required.

DIVA Project Confirmed

May 2011

Mechadyne is proud to have been selected as the valvetrain supplier for the ANR funded DIVAS project that will be run in conjunction with Renault and IFPen. The project will look at an innovative new method for reducing CO2 emissions in diesel engines by using a variable secondary valve lift to promote scavenging.  This approach, akin to what has been acheived with gasoline engines, yields increased output and potential for either a significant engine downsize or downspeed.
