FACT SHEETEngine brake type EBR-EPG/EBR-EPGC
Engine brake – Exhaust Pressure Governor
The Exhaust Pressure Governor is located in the exhaust outletof the turbo and is a pneumatic-controlled valve that chokes the
flow in the exhaust system and increases the back pressure on
the pistons during idling. The engine therefore works heavier and
keeps the work temperature on a suitable level.
When the exhaust brake is activated the valve is almost shut.
This gives a high back pressure on the pistons on their way up,
which results in deceleration of the engine and the vehicle.
In addition to the standard EPG (EBR-EPG) the EBR-EPGC also
gets some engine components from the Volvo Engine Brake (VEB).
The EBR-EPGC variant is for I-shift gearboxes and the EBR-
EPG is for other gearboxes (except Powertronic).

Multifunction control stalk
The control stalk for auxiliary brakes has three or five positions,
depending on the type of gearbox that the truck is equipped with.
A Automatic mode. Brake Blending is active if Cruise Control isinactive. When the brake pedal is depressed, the braking force is
blended between the ordinary brakes and the auxiliary brakes.
O All auxiliary brakes are off.
1-3 Brake level settings. Provides settings between 20 and 100%.
The total brake torque depends on which auxiliary brakes that are
fitted on the vehicle, load condition and retarder temperature. The
auxiliary brake is activated when the accelerator pedal is released.On
control stalk with setting 1 only gives full braking effect from the
Exhaust Pressure Governor.
B Brake program mode. On vehicles with I-Shift or Powertronic,
there is also a “B-button” that is used to activate the “brake pro-
gram”. This function provides faster down-changes during braking.
