DIESEL EXHAUST EMISSION FLUID HEATING SYSTEM
The diesel exhaust emission fluid used in the vehicle begins to freeze at -11 °C. The
engine begins to spray ureas to the exhaust system when its heat has increased. If the
fluid in the tank remained frozen when the engine heated, the engine cuts power since
there would be no urea spraying operation. Therefore, under cold acclimatization (at
temperatures of -7 °C or lower), the engine heats the diesel exhaust emission fluid tank
with hot water and the diesel exhaust emission fluid line going from tank to the injector
with the electric heater.
ELECTRONIC BRAKE SYSTEM (EBS)
Electronic brake system has both electronic and pneumatic infrastructure. Under
normal conditions the brake system is controlled electronically. The brake demand
coming from the driver is operated by control unit, the most suitable brake at that
condition is generated. This system has a higher performance as compared to
conventional systems. The system does not close itself in case of electronic failures, it
continues to run pneumatically.
EBS system includes the following functions:
1) Anti-Lock Braking System (ABS):
It prevents the rolling of the vehicle by
precluding the locking of the wheels during braking. It provides the steering stability in
sudden brakings.
2) Traction System (ASR
)
:
The ASR activates when the drive wheels spin in ramps,
slippery surfaces and during acceleration and it increases the driving safety by
reducing skid at minimum.
3) Drag Torque Control (DTC):
The wheels may be locked due to the inertia of the
drivelines in slippery surfaces, this system activates and increases the engine torque
and tries to provide roadholding.
4) Electronic Brake Balancing (EBD):
It distributes the necessary brake force
among wheels according to the vehicle’s load status and pad wear.
5)
Pad wear can be controlled, the thickness of the pads are continuously followed on
the dashboard.
6) Retarder Integration:
The system always interacts with retarder. The retarder
precludes the pads wear in light brakings, at the same time it reinforces the brake
system under normal conditions. Retarder system breakdowns when ABS function
operates.
Security functions do not work in electric failure events, the performance of the brakes
reduces, in this case the driver has to apply to the nearest authorized service carefully.
The security functions such as ABS, ASR and DTC are effective in reducing the
accidental risk, but the most important issue is to drive the vehicle appropriate to the
traffic and road conditions.
