Abstract:
A system for varying valve lift and duration in an automobile engine is provided. The system includes a guide, a slider, a rocker, a connecting rod and an oscillating cam. The slider is connected with rocker and the slider slides in the guide and one end of rocker is in contact with a primary cam follower and other end of rocker is connected with connecting rod. The slider provides sliding motion to the rocker. The oscillating cam is connected with connecting rod, and placed above a valve stem which operates the valve. The connecting rod provides oscillating motion to the oscillating cam. The oscillating motion of the oscillating cam varies the lift and duration of the valve and the range of oscillation of said oscillating cam is governed by the relative positioning of slider with rocker and contact point between primary cam follower and one end of rocker.  

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
