IN EARLIER POST HOW TO ADJUST Pmax OF THE INDIVIDUAL CYLINDER WE HAVE DISCUS CHANGING Pmax OF ENGINE OF ANY INDIVIDUAL CYLINDER. IN THIS POST WE WILL DISCUSS HOW TO CHANGE Pmax OF ENGINE OF ALL CYLINDERS AT ONCE. THIS IS CARRIED OUT BY CHANGING SETTING IN THE V.I.T SYSTEM.
THIS ADJUSTMENT IS VERY FINE TILL 2 DEGREE ADVANCE OR RETARD ONLY. FOR THIS PIVOT VALVE F1 AND F2 ARE AXIALLY DISPLACED.
FIRST RELEASE THE SCREW AND NUT WHICH SECURE THE BRACKET WITH THE PIVOT VALVE TO THE LARGER BRACKET THROUGH THE SLOTTED HOLES.
- INCREASE IN Pmax IS ACHIEVED BY MOVING THE PIVOT VALVE TOWARDS THE LEVER.
- DECREASE IN Pmax IS ACHIEVED BY MOVING THE PIVOT VALVE AWAY FROM THE LEVER.
