3. CAUTIONS FOR DI ENGINE
1) Cautions for DI Engine
This chapter describes the cautions for DI engine equipped vehicle. This includes the water separation
from engine, warning lights, symptoms when engine malfunctioning, causes and actions.
DI Engine 1.
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing electrically,
delivers high power and reduces less emission..
System Safety Mode 2.
When a severe failure has been occurred in a vehicle, the system safety mode is activated to protect the
system. It reduces the driving force, restricts the engine speed (rpm) and stops engine operation. Refer
to "Diagnosis" section in this manual.
Engine CHECK Warning Lamp 3.
The Engine CHECK warning lamp on the instrument cluster comes on when the fuel or
major electronic systems of the engine are not working properly. As a result, the
<008c0095008e00900095008c02c5009a004700970096009e008c009900470096009c009b0097009c009b00470094008800a00047008b008c008a0099008c0088009a008c0047009600990047009b008f008c0047008c0095008e00900095008c0047009400
8800a00047009a009b0088009300930055>
Water Separator Warning Lamp 4.
When the water level inside water separator in fuel filter exceeds a certain level (approx.
45 cc), this warning light comes on and buzzer sounds.
Also, the driving force of the vehicle decreases (torque reduction). If these conditions
occur, immediately drain the water from fuel filter.

(2) Di engine and its expected problems and remedies can be caused by
water in fuel
System supplement against paraffin separation ▶
In case of Diesel fuel, paraffin, one of the elements, can be separated from fuel during winter and then
can stick on the fuel filter blocking fuel flow and causing difficult starting finally. Oil companies supply
summer fuel and winter fuel by differentiating mixing ratio of kerosene and other elements by region and
season. However, above phenomenon can be happened if stations have poor facilities or sell improper
fuel for the season. In case of DI engine, purity of fuel is very important factor to keep internal
preciseness of HP pump and injector.
Accordingly, more dense mesh than conventional fuel filter is used. To prevent fuel filter internal clogging
due to paraffin separation, SYMC is using fuel line that high pressure and temperature fuel injected by
injector returns through fuel filter to have an effect of built-in heater (see fuel system).
System supplement and remedy against water in fuel ▶
As mentioned above, some gas stations supply fuel with excessive than specified water. In the
conventional IDI engine, excessive water in the fuel only causes dropping engine power or engine
hunting. However, fuel system in the DI engine consists of precise components so water in the fuel can
cause malfunctions of HP pump due to poor lubrication of pump caused by poor coating film during high
speed pumping and bacterization (under long period parking). To prevent problems can be caused by
excessive water in fuel, water separator is installed inside of fuel filter. When fuel is passing filter, water
that has relatively bigger specific gravity is accumulated on the bottom of the filter.
Water drain from water separator ▶
If water in the separator on the fuel filter exceeds a certain level, it will be supplied to HP pump with fuel,
so the engine ECU turns on warning lamp on the meter cluster and buzzer if water level is higher than a
certain level.
Due to engine layout, a customer cannot easily drain water from fuel filter directly, so if a customer
checks in to change engine oil, be sure to perform water drain from fuel filter.
Water
separator
To separate the water from the fuel filter,
remove the fuel filter assembly first.

1) Types of swirl
Swirl: One cylinder has two intake air ports, one is set horizontally and
the other one is set vertically. Swirl is the horizontal air flows in cylinder
due to the horizontal intake air ports.
Tumble: Tumble is the vertical air flows in cylinder due to the vertical
intake air port
Squish: Squish is the air flows due to the piston head. Normally, this is
appears at the final process of compression. In CRDi engine, the
piston head creates the bowl type squish.
2) Swirl control
In DI type diesel engine, the liquefied fuel is injected into the cylinder directly. If the fuel is evenly
distributed in short period, the combustion efficiency could be improved. To get this, there should be
good air flow in cylinder. In general, there are two intake ports, swirl port and tangential port, in each
cylinder. The swirl port generates the horizontal flow and the tangential port generates the longitudinal
flow. In low/mid load range, the tabgential port is closed to increase the horizontal flow. Fast flow
decreases the PM during combustion and increases the EGR ratio by better combustion efficiency.

Glow plug control unit
(GCU)
1. OVERVIEW
The pre-heating system for D20DTR engine has the glow plug to the cylinder head (combustion
chamber), and improves the cold start performance and reduces the emission level.
The pre-heating resistor (air heater) is used to heat the intake air.
This enables the diesel fuel to be ignited in low temperature condition.
The ECU receives the information such as, engine rpm, coolant temperature, engine torque, etc.,
through CAN communication during pre-heating process; and the pre-heating control unit controls the
pre-heating, heating during cranking and post-heating by the PWM control.

1. OVERVIEW
The low emission vehicle is being sold increasingly in the market as a countermeasure for complying
with the environment regulations such as a special act on Seoul metropolitan air quality improvement
and for reducing the PM (Particulate Material) from the diesel-powered vehicle. For the CDPF system,
the DOC (two-way catalytic converter or catalytic combustion system) fitted to the conventional diesel
engine has the high purification rate for HC or CO but not have a high reduction rate for the PM. For this
reason, a necessity has been raised in order to consider a countermeasure to reduce the PM since the
existing DOC can't meet the regulation, which is getting tighter.
This results in a development of the CDPF (Catalyst & Diesel Particulate Filter) that is combination of the
existing DOC (Diesel Oxydation Catalyst) and DPF (Diesel Particulate Filter). While the DOC converts
the CO and HC into the CO2 and H2O - unharmful to human body - using a oxidation reaction, the DPF
collects the PF (Particulate Material) for regeneration of it. However, each of these devices can only
reduce a part of the exhaust gas. This evoked the necessity of the CDPF with both features. The DOC
capacity is more on the manual transmission than the automatic transmission.
DPF(Diesel Particulate Filter) ▶DOC(Diesel Oxidation Catalyst) ▶
It is called as a oxidation catalyst, which purifies CO and HC in exhaust gas. The three-way catalyst is
used for the gasoline vehicle. But, the diesel engine oxidates CO and HC excepting NOx into H2O and
CO2 in order to purify the exhaust gas since the exhaust gas has a rich oxygen at all times.
It consists of mainly the aluminum and titanium and there is a porous thin film, which emits the exhaust
gas but does not emit the PM in it. It emits the exhaust gas generated during combustion and filters the
PM which is a byproduct of combustion to burn it when a certain amount of it is collected in the filter.
When a certain amount of the PM builds up, exposure to high exhaust gas causes carbon, the
fundamental ingredient in PM, to burn and release into the atmosphere in form of CO2.
