Summary:

In the previous study (SAE 2003-01-0022), I presented a mechanical continuous variable valve event and valve lift VRA which some versions can integrate the variable timing control. Besides the VRA, the system can be applied to various valve trains, such as DOHC, SOHC and Push rod.In this VRA part II, a few parts of VRA are developed. For example, positions of camshaft and control shaft, which are closely related, are developed to produce minimum or maximum valve event and valve lift at the least rotation of control shaft. The developments will allow the VRA to produce a faster response and require less operation.Second part of this study will present the application of the Double Intake Valve Control, which double VRA will control each intake valve separately, while only one intake camshaft is required. Furthermore, this system is expected to support various forms of the combustion, including the gasoline direct injection as well.The experiments for measuring the characteristics of some types of this VRA, such as torque and emission, will be implemented by using 4-stroke, single cylinder engine
