Engine Fuel System
Important DO NOT reuse high pressure fuel pipes
that have been removed from the engine for service procedures. If
a high pressure fuel pipe was removed for an engine service procedures,
replace it with a new pipe to prevent fuel leaks due to sealing surface
working face deformation.
The TK488CR/CR1 engines use a common rail fuel system.
The components of the fuel system are:
-
Fuel tank
-
Electric fuel pump (with pre-filter, 40 micron)
-
Primary Fuel filter/water separator (5 micron)
-
Secondary fuel filter (3 micron)
-
High pressure fuel pump
-
Common (high pressure fuel) rail
-
Electronic injection nozzles
