DIRECT INJECTION TYPE DIESEL ENGINE

CAUTIONS FOR DIRECT INJECTION TYPE DIESEL ENGINE
Direct Injection (DI) Type Diesel Engine
Compared to Indirect Injection (IDI) Type Diesel Engine that
uses mechanical fuel injection system, Direct Injection (DI)
Type Diesel Engine controls the amount of injected fuel and
the fuel injection timing electronically. This advanced engine
enhances the output power and reduces the noxious exhaust
gas (Co, HC, Nox....). Because the Direct Injection Diesel
Engine is operated by high pressure (1,600 bars), any removal,
modification or service of the engine may contaminate the
inside of the system and cause the system to malfunction. In
that case, the malfunction and any related systems are not
under warranty of this company.
Warning for Using Low Quality Fuel
The fuel system in DI engine equipped vehicle has many pre-
cisely machined components. Using low quality fuel could
result in a serious damage to the engine due to the water or
impurities in fuel. Never use the low quality fuel.
System Safety Mode
When the vehicle has a system error, the vehicle operates
in safety mode to maintain minimum driving conditions and
to prevent the system from being damaged. In this mode, the
engine driving force may be decreased or the engine may
stall. When this happens, have the system checked at the
Ssangyong Dealer or Ssangyong Authorized Service
Operation.

SAFETY PRECAUTIONS
Supplementary Heating Device
- FFH (Fuel Fired Heater)
This supplementary heater is a fuel burning type and improves
the heating effect by increasing the engine coolant
temperature.
- PTC (Positive Temperature Coefficient)
This supplementary heater is an electrical air heating type
and installed on the heater outlet port. This device improves
the heating effect by increasing the temperature of flowing
air into the passenger room.
FFH Operation
The FFH system operates up to more 2 minutes to burn the
residual fuel inside the system when stopping the engine
during its operation.
Therefore, a certain period of FFH operation after stopping
the engine is not a malfunction.
In initial operating stage, the fuel pump generates the oper-
ating sound and the FFH heater produces white smoke.
These are normal states to fill the fuel into the FFH fuel line.
