EMISSION CONTROL - K SERIES KV6

17-3-8

DESCRIPTION AND OPERATION

Vapour Separator
The vapour separator is installed at the front of the RH rear wheel arch, behind the wheel arch liner. The vapour 
separator prevents the charcoal in the EVAP canister being saturated with fuel, by separating any liquid from the 
vapour vented from the fuel tank. Separated fuel from the vapour separator drains back to the fuel tank through the 
vent pipe.

EVAP Canister
The EVAP canister is installed at the front of the RH rear wheel arch, behind the wheel arch liner. Charcoal in the 
EVAP canister absorbs and stores fuel from the vapour vented from the fuel tank. When the engine is running, fuel is 
purged from the EVAP canister when the purge valve opens and clean air is drawn through the charcoal.

EVAP Canister

1 Canister housing
2 Purge valve connection

3 Vapour separator connection
4 DMTL connection

Purge Valve
The purge valve is installed on the inlet manifold chamber, next to the throttle body, and connected to the EVAP 
canister by a vent pipe installed on the underside of the vehicle, next to the fuel delivery pipe.

The purge valve is controlled by the Engine Control Module (ECM) and remains closed below a preset coolant 
temperature and engine speed, to protect engine tune and catalytic converter performance. When engine operating 
conditions are suitable, the ECM opens the purge valve and the depression in the inlet manifold draws fuel vapour 
from the EVAP canister.

DMTL
The DMTL is connected to the atmospheric vent of the charcoal canister and incorporates an electric air pump, a 
normally open change-over valve and a 0.5 mm (0.020 in) reference orifice. The DMTL operates only after the ignition 
is switched off and is controlled by the ECM, which also monitors the air pump and the change-over valve for faults.

Air Filter 
The air filter prevents dust being drawn into the EVAP system. A breather tube connects the DMTL to the air filter, 
which is located above the RH rear wheelarch liner, immediately below the fuel filler cap.
