FUEL SYSTEM 6C – 47
8. Operate the nozzle tester and increase the in-line pressure to 34.3 - 44.1 MPa (350 - 450 kg/cm 2 ) so that the nozzle’s needle valve moves through its full lift.
Record full lift ‘L’. (Read dial gauge) Nozzle Full Lift mm (in) 0.25 ± 0.02 (0.0098 ± 0.00008)
Note:
The above operation is used to determine whether
Pre-lift confirmation 1. With the needle valve at full lift, release the nozzle tester handle.
Note: The in-line pressure will decrease and needle
2. Read the needle valve lift ‘liter’ from the dial gauge indication (once the needle valve has descended when Pre-lift measuring point: 2 ). Pre-lift mm Pressure kg/cm 2 (psi/kpa) Lift mm (in) 204 (2,901/20,000) 0.04 (0.0016)
Note:
This point can be found while the pressure is
