CONTROLS AND INSTRUMENTS
Particulate Matter (PM) Catalytic Converter
The PM catalytic converter uses an oxidation catalyst to reduce the unburned material
in PM in exhaust gases to water and carbon dioxide.
As a general rule, while idling, diesel engines have low exhaust gas temperatures. The
oxidation catalyst is not actively engaged, so the particles in the exhaust gases build
up inside the catalyst. If the engine is revved or the vehicle is started and accelerated
in this state, the temperature of the exhaust gas will increase sharply and the particles
that have built up inside the catalyst will be discharged.
WARNING
• The engine, exhaust piping, radiator, and other similar components will remain at
a high temperature for some time after the vehicle has been driven. Care must
be taken to avoid burns. You should wait until the engine and other components
have cooled down before carrying out inspections.
CAUTION
• An ultra-low sulfur content diesel fuel (10 ppm or less sulfur content) or a low
sulfur content diesel fuel (50 ppm or less sulfur content) must be used with PM
catalytic converter-equipped vehicles.
The use of poor quality fuel, water removers and other additives, gasoline,
kerosene, or alcohol-based fuel either as is or as part of a mixture can not only
lead to a badly affected fuel filter and poor sliding of fuel-lubricated components
within injectors, but also to engine breakdown as a result of the adverse effect
they have on the engine and the PM catalytic converter. If the vehicle is filled
with an incorrect fuel by mistake, the fuel must be fully removed from the
system before refilling with a correct fuel. If the engine were to be started with
an incorrect fuel in the system, dangerous situations such as the outbreak of
fire and engine damage could result.
