Engine Indicator  Faults

 

 

 

 

If there is doubt over the timing of the indicator drive cam with the piston position, then take an in phase indicator card with the fuel off the cylinder. The compression and expansion curves should overlap. If the diagram is positive in area then retard the indicator cam; If the diagram is negative in area, advance the indicator cam.
