OVERVIEW




The variable vane turbocharger, fitted to the exhaust manifold, makes it possible to vary the exhaust gas flow of the
turbine, dependent on engine operation. This improves the power transfer to the turbine wheel and compressor,
particularly at low engine speeds, thus increasing the boost pressure. The guide vanes are opened progressively as the
engine speed increases so that the power transfer always remains in balance with the required charger speed and the
required boost pressure level. Variable vanes facilitate better use of the exhaust gas energy so as to further improve
the efficiency of the turbocharger and thus of the engine, compared to the more conventional 'wastegate control'.
Advantages:
High torque at both high and low engine speeds
Continuous and optimum adjustment for all engine speeds
No wastegate valve required, exhaust energy is better utilised, less back-pressure in conjunction with same
compressor work
Low thermal and mechanical load improves engine power output
Lower emissions
Optimised fuel consumption over the entire engine speed range
A Direct Current (DC) rotary actuator motor operates a drive shaft. The drive shaft is connected to the vanes by an
actuating lever. Adjustment of the vanes is achieved by moving the actuating lever. When the drive shaft is turned, a
signal is created at the end of the drive shaft; this feedback signal is used to determine the angular position of the
vanes. This information is transmitted to the Engine Control Module (ECM).
The turbocharger is designed for fail safe operation. If a fault occurs regarding the control of the unit, the vanes default
to the fully open position so as to produce minimum boost. The ECM detects any malfunctions in the stepper motor and
generates Diagnostic Trouble Codes (DTC).
PRINCIPLES OF OPERATION
Item




A - Low Engine Speed
At low engine speeds the volume of exhaust gas is low so the vanes are moved towards the closed position to reduce
the turbine inlet area. This reduction causes an increase in the gas velocity into the turbine wheel thereby increasing
wheel speed and boost.
B - Moderate Engine Speed
As the engine speed increases and the volume of exhaust gas increases the vanes are moved towards the open position
to increase the turbine inlet area and maintain the gas velocity.
C - Maximum Engine Speed
At maximum engine speed the vanes are almost fully open maintaining the gas velocity into the turbine wheel.
Barometric Pressure Sensor
When the vehicle is driven at high altitudes the ambient pressure reduces causing the compressor wheel to do less work
for the same boost pressure. To prevent the turbine wheel from over-speeding under these conditions a barometric
pressure sensor, located in the ECM, protects the turbocharger by opening the vanes further to reduce the turbine wheel
speed. This is known as the altitude margin of the turbocharger.
Turbocharger Lubrication
The rapid acceleration and deceleration response demands of the turbocharger rely greatly on a steady flow of clean oil.
The oil supplied from the engine's lubrication system provides lubrication to the turbocharger's spindle and bearings,
while also acting as a coolant for the turbocharger centre housing.
To maintain the life expectancy of the turbocharger, it is essential that the oil has a free-flow through the turbocharger
and unrestricted return to the engines sump. It is therefore imperative that the engine oil is replenished at regular
service intervals with the recommended quality and quantity of oil.
Charge Air Cooler
The charge air cooler is used to increase the density of air as it flows from the turbocharger compressor to the intake
manifold.
Compression of the charge air by the turbocharger raises the temperature of the air. This generation of heat expands
the air density and consequently less oxygen is able to enter the cylinders, reducing the engines power. To overcome
this, the air is routed through the charge air cooler before it enters the engine; the temperature is reduced by
transferring the heat to atmosphere.

Item Part Number Description
1 - Vacuum pump
2 - Coolant pump
The coolant pump is installed at the front, LH side of the cylinder block and is secured with 4 bolts. The coolant pump is
driven by the accessory drive belt via the crankshaft. The engine thermostat is located in the rear of the coolant pump
housing and begins to open at 88°C (190°F).
For additional information, refer to: Engine Cooling (303-03 Engine Cooling - 2.4L Duratorq-TDCi HPCR (103kW/140PS) -
Puma, Description and Operation).
The vacuum pump is mounted on top of the cooling pump and is secured with 3 bolts. The vacuum pump is also driven
by the accessory drive belt via the crankshaft.

1 - Power steering pump
The power steering pump is located at the front, LH side of the cylinder block, directly below the coolant pump. The
power steering pump is attached to a mounting bracket via 3 bolts and the mounting bracket locates on the cylinder
block and ladder frame via 4 bolts.
For additional information, refer to: Power Steering (211-02 Power Steering, Description and Operation


The high-pressure fuel pump is located under the intake manifold, behind the coolant and vacuum pump assembly. The
fuel pump is driven by the timing chain at the front of the engine and includes a transfer pump and a high pressure
pump which are serviced as one unit.
The pump provides the interface between the low and high-pressure systems. Its function is to always provide sufficient
compressed fuel under all operating conditions and for the entire service life of the vehicle.
The transfer pump draws the fuel from the fuel tank, through the fuel filter, and then pumps the fuel to the highpressure
pump. The transfer pump maintains a constant fuel pressure through a regulating valve within the fuel pump;
this is known as transfer pressure.
The high-pressure pump receives fuel at transfer pressure from the transfer pump and increases the fuel pressure. The
high pressure fuel is then transferred from the high-pressure pump to the common rail.

אמנם החזקתי בלנדרובר כמס' חדשים , אפילו ביקרתי אצל גרשון במס' הזדמנויות , עדיין אני מתקשה להבין את פשר ההודעות האלו שהוא מעלה -
האם מישהו ממשתתפי הפורום יכול להאיר את עיניי בבקשה ? האם מדובר בשפת סתרים כלשהי שרק בעלי לנדרובר מבינים ?

אנשים רוצים לדעת איך בנוי DEFENDER PUMA
I have full info about this car from UK

[ניר ל]

מה זה דיפנדר פומה ? מי אותם אנשים שרוצים לדעת איך הוא בנוי ? למה העתקת עמודים מספר היצרן של הרכב לתוך שרשור בפורום מועילה למישהו ?

תעזרו לי כאן הא? לא רוצה למחוק הודעות שאולי מסייעות כאן למישהו באופן נשגב מבינתי ...
