(9) EGR control
A. Overview
The EGR (Electric-Exhaust Gas Recirculation) valve reduces the NOx emission level by recirculating
some of the exhaust gas to the intake system.
To meet Euro-V regulation, the capacity and response rate of E-EGR valve in D20DTR engine have
been greatly improved. The EGR cooler with high capacity reduces the Nox, and the bypass valve
reduces the CO and HC due to EGR gas before warming up.
Also, the engine ECU adjusts the E-EGR opening by using the air mass signal through HFM sensor. If
the exhaust gas gets into the intake manifold when the EGR valve is open, the amount of fresh air
through HFM sensor should be decresed.

F. Features
As EGR ratio goes up, smoke volume will be
higher. But, this lowers the combustion
chamber temperature and accordingly the
concentration of NOx is decreased. The point
with highest NOx is immediately after TDC.As EGR temperature goes up, the
concentration of NOx will be higher. Thus, it is
necessary to cool down the exhaust gas.
However, during engine cooled, it may cause
large amount of PM. To prevent this, the
exhaust gas is bypassed the EGR cooler.

PTC Fuse and Relay
(13) PTC heater control
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.

(15) CDPF control
A. Overview
As the solution for environmental regulations and PM Particle Material) of diesel engine, the low
emission vehicle is getting popular. This vehicle is equipped with an extra filter to collect the soot and
burn it again so that the amount of PM in the exhaust gas passed through the DOC (Diesel Oxidation
Catalyst) is reduced. The CDPF (Catalyst & Diesel Particulate Filter) is an integrated filter including
DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate Filter).
For details, refer to Chapter "CDPF".

D. Operation process
When the differential pressure sensor detects the pressure difference between the front and the rear
side of CDPF, the sensor sends signal indicating the soot is accumulated and the post injection is
performed to raise the temperature of exhaust gas. The amount of fuel injected is determined
according to the temperature of exhaust gas detected by the rear temperature sensor. If the
tem
perature is below 600°C, the amount of fuel injected is increased to raise the temperature. If
the tem
perature is over 600°C, the amount of fuel injected is decreased or not controlled. When
the engine is running in low load range, the amount of post injection and the amount of intake air are
controlled. It is to raise the temperature by increasing the amount of fuel while decreasing the amount
of intake air.

2. CHECKING CABLES AND WIRES
Check for loose connection or rust.
Check terminals and wires for corrosion due to electrolyte leakage.
Check terminals and wires for open circuit.
Check the wire insulation and coat for damage, cracks or deterioration.
Check if the conductive parts of the terminals do not contact with vehicle body or other metal
parts.
Check that the grounding part has continuity with mounting bolts and vehicle body.
Check that wires are properly routed.
Make sure that wires are securely fixed to avoid contact with sharp body parts and hightemperature
parts, such as the exhaust manifold and exhaust pipes.
The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be
secured tightly at regular intervals.
Secure the wiring between the fixed parts, such as the vehicle body, and vibrating parts, such
as the engine, after slackening it slightly to prevent it from being damaged. -
