EMISSION CONTROL SYSTEM
that the amount of vapour that escapes to the
atmosphere has been reduced.
• When driving with a low to medium load on the
engine, the fuel vapour absorbed by the,
canister is drawn into the P port of the throttle
body in the same way as in engines without
turbocharger.
• When driving with a high load on the engine, the
purge control valve opens and the fuel vapour
absorbed by the canister is drawn into the air
intake hose.

ENGINE - Emission Control System
The emission control system is basically the same as
that used in the 6G72 engine fitted to the PAJERO
MONTERO. However, the following additions have been
made to the system in vehicles for Europe, Hong Kong
and Singapore only.
(1)
Oxygen sensors and a front catalytic converter have
been added to reduce the level of exhaust gas
emissions.
(2)
The evaporative emission control system has been
improved as shown below. The fuel vapour intake
amount from the canister has been increased so
