2. INSPECTION AND ADJUSTMENT [Informative: Fuel injection valve structure] (b) Spray pattern inspection After adjustment to the specified valve opening pressure, use a nozzle tester and check the spray pattern and seat oil-tight- ness. Seat oil tightness check After injecting a few times, increase the pressure gradually. Hold the pressure for about 5 seconds at a little before the valve opening pressure of 1.96 MPa {20 kg/cm 2 }, and check to see that oil does not drip from the tip end of the nozzle. If extreme oil leak from the overflow joint exists during injection by the nozzle tester, check after retightening. If much oil is leaking, replace the nozzle assem- bly.
