Description

 

Adjustment of Fuel Pump Timing

 

Large engine

The timing can be altered by shifting the camshaft to the position relative to the crankshaft


For adjustable cam type engines timing can be altered by individual cams of the fuel pumps.
Individual unit timing checking up & adjustment required for movable cam type engine


For solid camshaft type, it is only required for checking on No. 1 unit.


How will you check pump timing if no TDC mark given on flywheel ?
In Main Engine

Make a marking between cross head and guide shoe while they are before TDC and also mark at the flywheel.
Turn the crank shaft in the same direction until the crosshead and guide shoe are at the previous mark (coincide)
Make the second marking on the fly wheel. We got two marks on the flywheel mid point between the two points is TDC.
Now 360º can be divided around the flywheel.


In Auxiliary Engine

 

Remove the fuel valve


Insert the rod onto the piston (mark on rod and flywheel)


Turn crank until the rod previous mark


Make the second marking on the fly wheel


Mid point between the two points is TDC


What points do you check on fuel pump when overhaul or how will you decide ?


Check plunger guide wear & tear


Check spring (length & stiffness, crack)


Plunger & barrel wear & tear, check clearance (5 microns for DO, 15 microns for HO) by dropping the plunger into the barrel it fall down slowly is OK


Check control sleeve and rack teeth for crack


Check the Delivery valve face


Check ‘O’ ring of fitted.


Metering of Fuel
Controlling the fuel amount in two ways, by means of a helix groove on the plunger or by means of control valves.


The quantity of fuel delivered is regulated by the vertical length of the helix where it is in line with the suction port.


This setting may be altered by rotating the plunger. In stop position, the vertical slot of the plunger is in lined with the spill port where then ports are opened and thus no injection occurred.
