Injection system
The injection pump (8) delivers fuel to the injec-
tor nozzle (5) via fuel line (6). The fuel, is then
injected into the combustion chamber above the
engine piston (3), where the extreme engine
compression causes the fuel to self-ignite.
Note:
For information on other maintenance and
adjustments of the engine, refer to the Serv-
ice manual „4-Stroke Internal Combustion
Engines“ (5.905-122).
