Description

 

 Adjustment Of Fuel Pump Timing

Fuel Injection Pumps – Marine Engineering

 

Function of fuel injection pumps

To supply accurate metered amount of fuel with sufficient pressure to open fuel injector in correct timing.

How to cut out fuel pump

Reduce the engine speed

By lifting the pump roller form cam peak and securing the pump roller guide

By making pump rack to zero position

 

How to notice the incorrect timing ?

Difficult to start the engine

Abnormal exhaust temperature reading 

Black smoke coming out

Irregular running of engine.

 

How to check the fuel injection pump timing ?

Lock off the starring mechanism

Start L.O pump

Open all indicator cock

By hair line method

 

Turn the engine so that the unit to be checked is toward the TDC of compression stroke (plunger upstroke) so that hair line marking on plunger and pump body are coincided.

 

When hair lines are coincided, stop turning and check the mark on the fly wheel whether timing is correct or not.

By removing deflector from fuel pump

 

Take out deflector on both sides of the fuel pump

 

Put hand torch on one side of pump and mirror on the other side

 

The light from torch will be visible on the mirror

 

Turn the engine so that the unit to be check is toward the TDC of compression (at plunger upstroke)

 

At one instant the light on mirror disappears. (When plunger covers the deflector port)

 

At this time, stop engine turning & check the mark on flywheel.

 

Adjustment of Fuel Pump Timing

Small engine

 

Slightly different variation can be adjusted:

 

By adding or reduction shims on the pump base, or 

 

By turning the plunger up and down adjustment screw on the pump roller guide, or 

 

By shifting the coupling flange between the pump and the drive side of the engine in case of combined unit system, (for small engine)
