An ideal Continuously Variable Valve Duration model
Summary
The model is an ideal representation of the CVVD mechanism that is described in these youTube videos: The model in Figure 1. is not intended to be accurate it is only intended to exhibit the ability to vary the speed of the cam lobe. The location of the CVVD disc relative to the timing shaft is changed and this modifies the speed characteristics of the cam lobe. In Figure 2 the CVVDdiscPosition.s signal is the location of the CVVD disc relative to the timing shaft, this starts off at 5mm then at 10 seconds goes to 0mm and then goes to -5mm. The position of the CVVD disc is centered at 10s resulting in the cam lobe speed being equal to the timing shaft. The CVVD disc is finally moved to the right by 5mm, resulting in the cam lobe rotating slowly when on the right side.
