At the front of the crankshaft, a tuned torsional vibration damper is incorporated into the crankshaft front pulley. At the rear of
the crankshaft a pressed steel drive plate, with a steel starter ring gear, is installed to transfer drive from the engine to the
transmission. The reluctor ring for the CKP (crankshaft position) sensor is integrated into the perimeter of the drive plate.
The crankshaft seals are located in the front and rear covers.
PISTONS AND CONNECTING RODS
The diameter of each piston is graded and precisely matched to each cylinder bore to help reduce noise. In the vertical plane,
the pistons have a slight barrel form, which helps to ensure a reliable oil film is maintained between the piston and the
cylinder bore. A solid film lubricant coating is applied to both reaction faces of the piston to reduce wear and improve fuel
economy.
A three-ring piston-sealing system is used. The steel top ring is treated with a PVD (physical vapor deposition) peripheral
coating. PVD is a coating technique where material can be deposited with improved properties to ensure good cylinder bore
compatibility and wear resistance. A Napier center ring helps cylinder pressure and oil management, while the three-piece oil
control lower ring is produced from nitrided steel.
The pistons are cooled with engine oil from four piston cooling jets installed under the valley of the cylinder block. Each piston
cooling jet sprays oil onto the underside of the two adjacent pistons, one from each cylinder bank.
The connecting rods are forged from high strength steel. The cap is fracture-split from the rod to ensure precision re-assembly
for bearing shell alignment. There are three grades of large end bearing available, each being color coded. For further
information refer to Engine - 5.0L, Vehicles Without: Supercharger - General Procedures.

enable setting of inlet and exhaust valve clearances.
Each timing chain has a hydraulic tensioner operated by engine oil pressure. The chain tensioners incorporate a ratchet
mechanism, which maintains tension while the engine is stopped to eliminate start-up noise. The chains are lubricated with
engine oil from jets located at the front of the engine block. Nylon chain guides control chain motion on the drive side. VALVE TRAIN

Accessory Drive - V8 S/C 5.0L Petrol - Accessory Drive - Overview
Description and Operation
OVERVIEW
The accessory drive is a belt system powered by a pulley attached to the front of the crankshaft. The crankshaft pulley, which
incorporates a torsional vibration damper, drives two drive belts. An automatic belt tensioner in each belt run maintains the
drive belt at the correct tension. Together with idler pulleys, the belt tensioners also guide the drive belts clear of obstructions
and set the correct 'wrap-around' of the accessory component drive pulleys to ensure a slip-free drive.
PRIMARY DRIVE BELT
The primary drive belt is a six-ribbed poly-V belt that drives the:
Coolant pump
Power steering pump
A/C (air conditioning) compressor
Generator.
SECONDARY DRIVE BELT
The secondary drive belt is an eight-ribbed poly-V belt that drives the SC (supercharger).
BELT TENSIONERS
Each belt tensioner consists of an idler pulley on the end of a spring loaded pivot arm. The pivot arms can be turned manually
for removal and installation of the drive belts.
Each belt tensioners is calibrated to automatically maintain the correct tension in the related drive belt.

ECM ADAPTIONS System Operation
The ECM (engine control module) has the ability to adapt the input values it uses to control certain outputs. This capability
maintains engine refinement and ensures the engine emissions remain within the legislated limits. The components which
have adaptions associated with them are:
The APP (accelerator pedal position) sensor
The heated oxygen sensors
The MAFT (mass air flow and temperature) sensors
The CKP (crankshaft position) sensor
Electronic throttle.
OXYGEN AND MAFT SENSORS
There are several adaptive maps associated with the fueling strategy. Within the fueling strategy the ECM calculates short-term adaptions and long term adaptions. The ECM will monitor the deterioration of the heated oxygen sensors over a period of time. It will also monitor the current correction associated with the sensors.
The ECM will store a fault code in circumstances where an adaption is forced to exceed its operating parameters. At the same time, the ECM will record the engine speed, engine load and intake air temperature.
CRANKSHAFT POSITION SENSOR
The characteristics of the signal supplied by the CKP sensor are learned by the ECM. This enables the ECM to set an adaption and support the engine misfire detection function. Due to the small variation between different drive plates and different CKP sensors, the adaption must be reset if either component is renewed, or removed and refitted. It is also necessary to reset the
drive plate adaption if the ECM is renewed or replaced. The ECM supports four drive plate adaptions for the CKP sensor. Each adaption relates to a specific engine speed range. The engine speed ranges are detailed in the table below:
Adaption Engine Speed, rev/min 1 1800 - 3000 2 3001 - 3800 3 3801 - 4600 4 4601 - 5400 MISFIRE DETECTION
Legislation requires that the ECM must be able to detect the presence of an engine misfire. It must be able to detect misfires at two separate levels. The first level is a misfire that could lead to the legislated emissions limit being exceeded by a given
amount. The second level is a misfire that may cause catalytic converter damage.
The ECM monitors the number of misfire occurrences within two engine speed ranges. If the ECM detects more than a predetermined number of misfire occurrences within either of these two ranges, over two consecutive journeys, it will record a
fault code and details of the engine speed, engine load and engine coolant temperature. In addition, the ECM monitors the number of misfire occurrences that happen in a 'window' of 200 engine revolutions. The misfire occurrences are assigned a
weighting according to their likely impact on the catalytic converters. If the number of misfires exceeds a given value, the ECM stores catalytic converter damage fault codes, along with the engine speed, engine load and engine coolant temperature.
The signal from the CKP sensor indicates how fast the poles on the drive plate are passing the sensor tip. A sine wave is generated each time a pole passes the sensor tip. The ECM can detect variations in drive plate speed by monitoring the sine wave signal supplied by the crankshaft position sensor. By assessing this signal, the ECM can detect the presence of an engine misfire. At this time, the ECM will assess the amount of variation in the signal received from the CKP sensor and assign a roughness value to it. This roughness value can be viewed within the real time monitoring feature using Jaguar approved
diagnostic equipment. TheECM will evaluate the signal against a number of factors and will decide whether to record the occurrence or ignore it. The ECM can assign a roughness and misfire signal for each cylinder.
