Introduction .................................................... 15-49
Operation ....................................................... 15-50
Introduction
The crankcase ventilation filter is built into the
underside of the rocker cover. The filter separates
engine oil from the blow by gas. The engine oil drains
back into the rocker arm housing.
No routine maintenance is required.
3. 15 - Engine

00 - General
15 - 50 9813/7500-2 15 - 50
Operation
The engine oil is separated from the blow-by gas in
the oil mist separator in two phases:
1. The blow-by gas is accelerated through the holes
in the nozzle plate. This accelerated blow-by gas
hits a wall in the oil mist separator housing central
section and the engine oil droplets contained in
the blow-by gas are separated. The vertical fins
on the wall improve the separation of the engine
oil from the blow-by gases and also help engine
oil to drain downwards. Once enough separated
engine oil gets collected to open the check valve
which is installed in the oil drainage duct the
separated engine oil flows via the oil drainage
duct back into the rocker arm housing. The check
valve also prevents the blow-by gases in the
rocker arm housing from entering the oil mist
separator via the oil drainage duct.

Introduction
The rocker assembly is an indirect valve actuating
system consisting of rocker arms and a shaft.
The rocker arm is an oscillating lever that conveys
radial movement from the cam lobe into linear
movement at the poppet valve to open it. One end is
raised and lowered by a rotating lobe of the camshaft
via a tappet and push rod while the other end acts
on the bridge piece which is connected to the valve
stem.

Introduction
The crankshaft position sensor is a device used
to monitor the position or rotational speed of the
crankshaft. This information is used by the ECM
(Engine Control Module) to control the ignition
system timing and other engine parameters.

03 - Crankshaft Position
15 - 97 9813/7500-2 15 - 97
Operation
The crankshaft position sensor is an inductive sensor
that has a sensor coil and a permanent magnet.
The permanent magnet of the crankshaft position
sensor produces a magnetic field. The engine
flywheel has bores arranged at a distance of
6° to each other with an exception of 18° gap.
When the flywheel rotates, changes in the magnetic
field generates the inductive voltage in the coil of
the crankshaft position sensor. The ECM (Engine
Control Module) uses these signals to determine the
engine speed and the crankshaft angle with the help
of the 18° gap.

Operation ....................................................... 15-99
Introduction
The camshaft position sensor is used to determine
the compression stroke of the 1st cylinder. It sends
the camshaft position electrical signals to ECM
(Engine Control Module), so that the ECM knows
which cylinder to inject the fuel into. If the crankshaft
position sensor fails, the engine speed and the
crankshaft position can also be determined from
these signals.

Operation
The camshaft position sensor is a Hall effect
sensor and has a permanent magnet and evaluation
electronics.
The permanent magnet of the camshaft position
sensor produces a magnetic field. As the camshaft
rotates, the gaps in the pulse wheel result in changes
to the magnetic field. The evaluation electronics
of the camshaft position sensor transform these
changes to the magnetic field into the switch signals
and forward them to the ECM (Engine Control
Module).

The ECM (Engine Control Module) uses the coolant
outlet temperature sensor to detect the actual
coolant temperature at the engine outlet. There is a
negative temperature coefficient resistor inside the
coolant outlet temperature sensor which senses the
coolant outlet temperature.

Operation
Inside the coolant outlet temperature sensor there is
a negative temperature coefficient resistor. For the
negative temperature coefficient resistor, the electric
resistance decreases as the temperature increases.
The temperature of the coolant in contact with
the coolant outlet temperature sensor influences
the temperature of the measuring probe inside
the sensor and thus the magnitude of the electric
resistance. The ECM (Engine Control Module)
gives the related temperature based on the electric
resistance.

Introduction
The ambient air temperature sensor is located close
to the air filter intake inside the cooling compartment.
The sensor measures the air temperature at the
engine air filter intake.
The signal from the sensor is connected to the engine
interface ECU (Electronic Control Unit) and is part of
the MTU engine installation. If faults are suspected
contact a designated MTU dealer. Refer to: PIL

Introduction .................................................. 15-103
Operation ..................................................... 15-104
Introduction
The turbo outlet air temperature sensor (if installed)
is also known as the compressor housing charge-air
temperature sensor.
The sensor is located in the compressor outlet
on the turbocharger. The ECM (Engine Control
Module) uses the signal from the turbo outlet air
temperature sensor to detect the air temperature at
the compressor outlet of the turbocharger.
The ECM uses this information to find if the turbo
outlet air actuator must be triggered, and if the
injection must be adapted to protect the exhaust
turbocharger from high thermal loads.

Operation
The turbo outlet air temperature sensor has a
negative temperature coefficient resistor inside it.
The electric resistance of the sensor decreases
as the temperature increases. The ECM (Engine
Control Module) finds the relevant temperature
based on the electric resistance.

Operation ..................................................... 15-106
Introduction
The engine oil level sensor measures the level
of the engine oil in the oil sump. A pre-resistor
and a resistor wire are connected in parallel
and a negative temperature coefficient resistor is
connected in series inside the engine oil level sensor.
The resistor wire is located in the measuring probe.
The measuring probe will be put fully into the engine
oil if the engine oil level is correct.

15 - 106 9813/7500-2 15 - 106
Operation
The measuring probe of the engine oil level sensor
is positioned fully into the engine oil if the oil level is
correct.
The engine oil enters the measuring probe of the
engine oil level sensor through a supply bore and
touches the resistor wire. The total resistance at the
engine oil level sensor changes as the resistor wire
is immersed more or less in the engine oil. As the
engine oil level decreases, the total resistance also
decreases. As the engine oil level increases, the total
resistance also increases.
When the ignition is switched on, the ECM (Engine
Control Module) supplies a measuring voltage to the
engine oil level sensor every 6s. It checks the total
resistance of the engine oil level sensor and finds the
current engine oil level in the oil sump.
The engine oil level must be checked in the normal
way at the specified maintenance intervals. Refer to:
PIL 15-21-00.

Introduction .................................................. 15-107
Operation ..................................................... 15-108
Introduction
The lambda sensor is also called a wideband
zirconia sensor. It is connected to the ECM (Engine
Control Module). It is controlled by a separate micro-
controller. The micro-controller controls the heater,
the pump cell and the reference cell. It also monitors
the operating temperature and the sensor findings.
The measuring current is from 0 to 4 mA.

15 - 108 9813/7500-2 15 - 108
Operation
The lambda sensor is calibrated through a balancing
resistor integrated into the connector. During
operation, the lambda sensor is re-calibrated in
regular intervals during coasting.
The lambda sensor has a ceramic element coated
with platinum which acts as electrodes carrying a
sensor signal to the wires when it contacts the
exhaust gases. At high temperatures, the zirconia
element causes the transfer of oxygen ions which
creates a voltage. If the difference of oxygen
concentration in the exhaust gas and the ambient
air is more, higher voltage is produced. This voltage
difference helps the air-fuel mixture and the engine
emission to be kept within the required limit.
