Injection valve
16.4.1 Description
Data and dimension
Orifices: 10
pcs
Orifice dia.:
0.54 mm
Angle: 155°
Opening press: See chapter 06.
The injection valve is centrally located in the cylinder head and
includes the nozzle holder and the nozzle (15), see Fig 16-4. The
fuel enters the nozzle holder sideways through a connection piece
(2) mounted into the nozzle holder.
The nozzles receive high pressure fuel from the injection pipe
and inject this fuel into the combustion chamber as a very fine
spray. The pressure at which the nozzle operate can be corrected
by turning the adjusting screw (7) in the injection valve.
