EMISSION CONTROL
1
DESCRIPTION AND OPERATION EMISSION CONTROL
Three systems are used to control the vehicle
atmospheric emissions, these are:
- Engine crankcase fume emissions.
- Fuel tank Evaporative emissions
- Engine exhaust gas emissions.
Crankcase ventilation system
The crankcase ventilation system, which is an integral
part of the air supply to the engine combustion
chambers, is often overlooked when diagnosing
problems associated with engine performance. A
blocked ventilation pipe or excessive air...

DESCRIPTION AND OPERATION EXHAUST SYSTEM
1.Manifold to front pipe connection.
2.Front oxygen sensor.
3.Front silencer support bracket.
4.Rear oxygen sensor.
5.Front pipe to silencer joint.
6.Silencer rear support bracket.
7.Rear silencer support bracket.

DESCRIPTION AND OPERATION Exhaust emission control.
The multiport Sequential Fuel injection (SFi) system
provides accurately metered quantities of fuel to the
combustion chambers to ensure the most efficient air
to fuel ratio under all conditions of operation. A further
improvement to combustion is made by measuring the
oxygen content of the exhaust gases to enable the
quantity of fuel injected to be varied, according to
conditions, to correct any unsatisfactory composition
of the...

DESCRIPTION AND OPERATION EVAPORATIVE EMISSION CONTROL SYSTEM
The system is designed to prevent harmful fuel vapour
from escaping to the atmosphere. The system
consists of a vapour separator tank, connected to the
fuel tank and located between the body inner and
outer panels on the right hand side of the vehicle near
the rear wheel arch. An Evaporative Emissions
(EVAP) canister, containing activated charcoal, is
positioned in the engine compartment attached to the
front right...

FAULT DIAGNOSIS TESTING EVAPORATIVE EMISSION CONTROL
Equipment required.
Nitrogen cylinder (compressed air may be used to
pressure the system when there has NEVER been
fuel present in the fuel or evaporative control
systems).
The following pressure test procedure is intended to
provide a method for ensuring that the system does
not leak excessively and will effectively control
evaporative emissions.
Water manometer (0 - 30 H2O or more).
Pipework and a T piece.
Method.
