FUEL INJECTION CONTROL
energy returned by the piezo actuator is reused, which keeps down the amount of energy that has to be sup-
plied for the next injection process.
Engine Synchronisation
One of the determining factors for fuel injection control is knowing the position of each of the pistons in their
respective cylinders at all times.
The angular position is measured by means of a magneto-inductive sensor which is excited by the teeth
machined onto the flywheel; this is known as the crankshaft position sensor. The flywheel has 60 teeth, each 6
degrees apart; 2 of these teeth are missing to form a notch.
A second sensor (Hall-effect sensor), stimulated by a tooth machined onto the camshaft, which turns at half
the engine speed, provides a signal relating to the progress of the injection cycle. Indeed, when the piston of
cylinder 1 is at top dead centre (TDC), either at the end of the compression stroke or at the end of the exhaust
stroke, the camshaft position sensor enables a distinction to be made between these two states.
By comparing the signals from these two sensors, the computer is able to provide all its systems with synchro-
nisation parameters, namely: the angular position of the flywheel, engine speed, the number of the active fuel
injector and the progress of the injection cycle.
This module also supplies the system with the rotation speed signal.
The camshaft position sensor is only used when starting the engine. As soon as the engine is running by itself
(not being cranked by the starter), the signal provided by the crankshaft position sensor is sufficient. If the
camshaft position sensor should fail while the engine is running, this will not affect the operation of the engine.
Quantity of Fuel Injected and Control of Start of Injection
 The parameters for controlling injection are, for each cylinder, the quantity to be injected and the start of
injection. These are calculated by the ECM from the following information:
- Engine speed.
- Accelerator pedal position.
- Turbocharge air pressure.
- Engine coolant temperature.
- Intake air temperature.
- Fuel pump temperature.
- Mass air flow.
- Pressure of fuel in the rail.
Station to Station Flow Regulation
The aim of this regulation process is to facilitate smooth engine operation by compensating for the system
variations (fuel injectors, compression rate, etc.) which affect the torque generated by each cylinder during
combustion.
The regulation process is only active at idle speed, with a warm engine and on condition that the engine speed
is sufficiently stable. An injection timing correction coefficient is assigned to each cylinder; this is "learning" all
the time the regulation process is active and remains fixed at the last value that was learned when the regula-
tion is inactive.
At each new cycle, the coefficients are initialised to 1.
Cylinder Balancing Control
This controller allows smooth behavior of running engine, reduction of noise and oscillations in the drivetrain
by compensating for system dispersions (fuel injectors, compression ratio, manufacturing tolerances of cylin-
ders or valves...) having an influence on the torque generated by each cylinder during combustion.
The controller is only activated if engine is in idle, warm and not too rough. Corrective coefficient on the injec-
tion time is associated with each cylinder that is learnt as soon as the regulation is active. Otherwise it remains
with its last memorized value.
At each new driving cycle, coefficients are initialized to 1.

NOTE:
Before any work is carried out on the high pressure injection system, protect:
 the accessories and timing belts,
 the electrical accessories, (starter, alternator, electric power assisted steering pump),
 the flywheel surface, to prevent any diesel from running onto the clutch friction plate.
 Check that you have plugs for the unions to be opened (set of plugs available from the Parts Department).
The plugs are single-use only. After use, they must be discarded (once used they are soiled and cleaning is
not sufficient to make them reusable). Unused plugs must be discarded.
 Check that you have hermetically resealable plastic bags for storing removed parts. Stored parts will there-
fore be less subject to the risk of impurities. The bags are to be used once only, and discarded after use.
 Use lint-free cleaning cloths. Using normal cloth or paper is prohibited. They are not lint-free and could con-
taminate the fuel circuit. Each cloth should only be used once.
 Use fresh cleaning agent for each operation (used cleaning agent is contaminated). Pour it into an uncon-
taminated container.
 For each operation, use a clean brush in good condition (the brush must not shed its bristles).
 Use a brush and cleaning agent to clean the unions to be opened.
 Blast compressed air over the cleaned parts (tools, workbench, the parts, unions and injection system
zones). Check that no bristles remain.
 Wash your hands before and during the operation if necessary.
 When wearing leather protective gloves cover them with latex gloves to prevent contamination.
INSTRUCTIONS TO BE FOLLOWED WHEN CARRYING OUT ANY WORK
 As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.
The plugs to be used are available from the Parts Department. The plugs must not be reused under any cir-
cumstances.
 Seal the pouch shut, even if it has to be opened shortly afterwards. Ambient air carries contamination.
 All components removed from the injection system must be stored in a hermetically sealed plastic bag once
they have been plugged.
 Using a brush, cleaning agent, air gun, sponge or normal cloth is strictly prohibited once the circuit has been
opened. These items could allow contamination to enter the system.
 A new component replacing an old one must not be removed from its packaging until it is to be fitted to the
vehicle.

ENGINE ASSEMBLY
4. Remove engine mounting insulator (RH) (1), engine mounting
bracket (RH) (2) and engine mounting stay (3).
5. Remove engine mounting through bolt-securing nut (A).
6. Carefully lower jack, or raise lift to remove the engine and the transaxle assembly.
CAUTION:
 Make sure that no part interferes with the vehicle side.
 Before and during this lifting, always check if any harnesses are left connected.
 During the removal, always be careful to prevent the vehicle from falling off the lift due to
changes in the center of gravity.
 If necessary, support the vehicle by setting jack or suitable tool at the rear.
Separation
1. Remove starter motor. Refer to STR-13, "Removal and Installation".
2. Lift with a hoist and separate the engine from the transaxle assembly. Refer to EM-89, "
Exploded View".
INSTALLATION
Installation is in the reverse order of removal.
 Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
 Make sure that each mounting insulator is seated properly, and tighten mounting nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
 Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-19, "
Fluids and Lubricants".
 Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
 Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
