C. Idle Speed Controller
The idle speed controller consists of 2 principal modules:
The first module determines the required idle speed according to:
* The operating conditions of the engine (coolant temperature, gear engaged)
* Any activation of the electrical consumers (power steering, air conditioning, others)
* The battery voltage
* The presence of any faults liable to interface with the rail pressure control or the injection
control. In this case, increase the idle speed to prevent the engine from stalling.
The second module is responsible for providing closed loop control of the engine's idle speed
by adapting the minimum fuel according to the difference between the required idle speed and
the engine speed. -

D. Flow Limitation
The flow limitation strategy is based on the following strategies:
The flow limitation depending on the filling of the engine with air is determined according to
the engine speed and the air flow. This limitation allows smoke emissions to be reduced
during stabilized running.
The flow limitation depending on the atmospheric pressure is determined according to the
engine speed and the atmospheric pressure. It allows smoke emissions to be reduced
when driving at altitude.
The full load flow curve is determined according to the gear engaged and the engine
speed. It allows the maximum torque delivered by the engine to be limited.
A performance limitation is introduced if faults liable to upset the rail pressure control or the
injection control are detected by the system. In this case, and depending on the gravity of
the fault, the system activates: -
-
-
-
Reduced fuel logic 1: Guarantees 75 % of the performance without limiting the engine speed.
Reduced fuel logic 2: Guarantees 50 % of the performance with the engine speed limited to
3,000 rpm.
Reduce fuel logic 3: Limits the engine speed to 2,000 rpm.
The system chooses the lowest of all values.
A correction depending on the coolant temperature is added to the flow limitation. This correction
makes it possible to reduce the mechanical stresses while the engine is warming up.
The correction is determined according to the coolant temperature, the engine speed and the
time which has passed since starting.
E. Superchager Flow Demand
The supercharge flow is calculated according to the engine speed and the coolant temperature. A
correction depending on the air temperature and the atmospheric pressure is made in order to
increase the supercharge flow during cold starts. It is possible to alter the supercharge flow value
by adding a flow offset with the aid of the diagnostic tool

A. Overview
The supplementary electrical heater is installed in DI engine equipped vehicle as a basic
equipment. The PTC system is operated according to two temperature values measured at the
coolant temperature sensor and HFM sensor. This device is mounted in the heater air outlet and
increase the temperature of air to the passenger compartment. Because PTC system is heated by
electrical power, high capacity alternator is required. PTC does not operate during engine
cranking, while the battery voltage is lower than 11 V or during preheating process of glow plugs.

1. DESCRIPTION AND OPERATION
1) Cleanliness and Care
An automobile engine is a combination of many machined, honed, polished and lapped surfaces
with tolerances that are measured in the ten-thousanths of an inch.
When any internal engine parts are serviced, care and cleanliness are important.
A liberal coating of enigne oil should be applied to friction areas during assembly, to protect and
lubricate the surfaces on initial operation. Proper cleaning and protection of machined surfaces
and friction areas is part of the repair procedure.
This is considered standard shop practice even if not specifically stated.
Whenever valve train components are removed for service, they should be kept in order. They
should be installed in the same locations, and with the same mating surfaces, as when they were
removed.
Battery cables should be disconnected before any major work is performed on the engine. Failure
to disconnect cables may result in damage to wire harness or other electrical parts.

2) On-engine Service
Disconnect the negative battery cable before removing or installing any electrical unit, or
when a tool or equipment could easily come in contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal injury and damage to the vehicle. The
ignition must also be in LOCK unless otherwise noted. -
Any time the air cleaner is removed, the intake opening should be covered. This will protect
against accidental entrance of foreign material, which could follow the intake passage into
the cylinder and cause extensive damage when the engine is started. -

Leakage Test ▶
Warm the engine up to normal operating temperature.
Disconnect the negative battery cable.
Remove the spark plugs.
Check the coolant level by opening the coolant reservoir cap and replenish if insufficient.
Open the engine oil filler cap.
Connect the tester to air pressure line and adjust the scale of tester.
Install the connecting hose to spark plug hole.
Position the piston of No.1 cylinder at TDC by rotating the crankshaft.
Connect the connecting hose to tester and measure the leakage volume after blowing up
5 bar of compressed air. -

-
Measure the leakage volume in the completely opening condition of throttle valve by pulling
the acceleration cable. -
Perform the pressure test according to the firing order. -
Firing Order: 1 - 3 - 4 - 2 -
Compare the leakage pressure with the specifications. -
