OVERVIEW
The Ingenium I4 2.0 Diesel engine has an engine management system
controlled by the Engine Control Module (ECM) which monitors, adapts and
precisely controls the fuel injection. The ECM uses multiple sensor inputs
and precision control of actuators to achieve optimum performance during
all driving conditions.
The ECM controls fuel delivery to all four cylinders via a fuel rail injection
system. The fuel rail system uses a common fuel rail to accumulate highly
pressurized fuel and feed the four, electronically controlled injectors. The
fuel rail is located in close proximity to the injectors, which assists in
maintaining full system pressure at each injector at all times.
The ECM uses the drive by wire principle for acceleration control.
Accelerator pedal demand is communicated to the ECM by signals from an
Accelerator Pedal Position (APP) sensor. The ECM uses the signals to
determine the position, rate of movement and direction of movement of the
accelerator pedal. The ECM then uses this data, along with other engine
information from other sensors, to achieve the optimum engine response.

INSTALLATION
Check cylinder head face for distortion, across the center and from
corner to corner.
CAUTION:
Make sure that the dowels and dowel holes are clean and
free from debris and foreign material.
NOTE:
The cylinder head gasket must be installed over the cylinder
head to cylinder block dow
