7.21 Exhaust gas cleaning system
ET65/404F-22T and ET90 DPF are equipped with a diesel particulate filter.
The soot produced by burning diesel fuel is collected and burned in the
diesel particulate filter at regular intervals. This process is called
regeneration.
Regeneration takes about 30 minutes.
The more often the automatic regeneration mode is corrected or modified,
the longer regeneration takes.
If the dirt in the diesel particulate filter reaches a critical value, engine
power is reduced and vehicle operation has to be stopped.
Regeneration is performed only if the engine is at operating temperature.
Health hazard due to exhaust gases!
Can cause serious health hazards or death.
► Do not inhale exhaust gases.
► Use only exhaust-gas suction systems suitable for exhaust-gas
temperatures of up to 600 °C (1112 °F).
► Provide for sufficient ventilation when operating in enclosed areas.
Burn hazard at the exhaust system!
During regeneration, the exhaust system can develop exhaust-gas
temperatures of about 600 °C (1112 °F), even if the engine is running at
an idle speedwhich can cause serious burns or death.
► Keep a safe distance from the exhaust system.
Fire hazard during regeneration!
Hot exhaust gases in easily flammable surroundings can cause serious
injury or death.
► In environments with easily flammable material, disable the automatic
regeneration mode (ET65/404F-22T only).
► Do not perform manual regeneration in environments with easily
flammable material or standstill regeneration.
► Use only exhaust-gas suction systems suitable for exhaust-gas
temperatures of up to 600 °C (1112 °F).
