Webadjusted independently, allowing the valve overlap (the time that intake and exhaust valves are both open) to be varied as well. Refer to the diagram and description below to help … WebThis movement is controlled by engine management system according to need, and actuated by hydraulic valve gears. Note that cam-phasing VVT cannot vary the duration of valve opening. It just allows earlier or later valve opening. Earlier open results in earlier close, of course. It also cannot vary the valve lift, unlike cam-changing VVT.
