MBE 900 OPERATOR'S MANUAL
NOTE:
In addition to the fourteen digit number
etched on the crankcase, there is a
ten digit number used for warranty
and service that is found on the
DDEC-ECU label. The ten digit
number is derived from the fourteen
digit number (see Figure 14).
Description of the Engine
All MBE900 engines are
water-cooled, four-stroke,
direct-injection diesel engines.
The cylinders are arranged inline on
both the 6-cylinder and 4-cylinder
models. Each has a separate fuel
injection pump (unit pump) with a
short injection line to the injection
nozzle, which is located in the center
of the combustion chamber. The unit
pumps are attached to the crankcase
and are driven from the camshaft.
Each cylinder has two intake valves
and one exhaust valve.
Charge-air cooling and an exhaust gas
turbocharger are standard equipment
on all MBE900 engines (charge
pressure limitation is optional).
The engine has a fully electronic
control system, which regulates the
fuel injection quantity and timing
using solenoid valves, allowing
extremely low-emission operation.
The control system consists of an
engine-resident pump and nozzle
control unit (the DDEC-ECU) and a
vehicle control unit (the DDEC-VCU).
The two are connected by a proprietary
datalink.
Engine braking is controlled by a
pneumatic and hydraulic (6-cylinder)
operated exhaust brake on the
turbocharger and by a constant-throttle
system (optional).
