2. Checking an injection valve
Before commissioning the instructions and directions of the test bench manufac-
turer must be observed.
From time to time check the pressure gauges of the test bench with a master pres-
sure gauge and adjust them if necessary.
Remark: The work station must be clean; welding and grinding should not be done
nearby!
⇒ Remove combustion residues and clean nozzle tip externally with a brass
wire brush.
⇒ Place injection valve 1 with nozzle tip pointing downwards into support 20 of
test bench 94272 and fasten it with two Allen screws 2 and spring cages 24.
⇒ Tighten high pressure hose 21 of the test bench with connecting piece
94272b.
⇒ Start the test bench following the proper manufacturer’s instructions.
⇒ Bring the injection valve to spray with a few short pump jerks, and then ob-
serve at what pressure the injection valve opens, applying slow, equal pump
jerks.
Danger of injuries! Never hold fingers or hands directly before the spray holes of
the nozzle tip!
