SING THE PARTICLE FILTER
WARNING
When launching the regeneration, fuel is burned directly in the DPF. The heat is used to
regenerate the particle filter and the combustion increases the temperature of exhaust
gas to a temperature close to 600°C. In case of insufficient regeneration of the DPF, the
monitor displays the DPF regeneration icon.
The regeneration of the DPF must be carried out in a well ventilated place. Carbon mo-
noxide (CO²) that is contained in the exhaust gas is colourless and odourless, and can
cause carbon monoxide poisoning which is dangerous to health.
The DPF destroys the harmful substances contained in the exhaust gas using a catalytic conver-
ter and a particle filter that prevents the diffusion of soot in the atmosphere. The regeneration of
the DPF is necessary to prevent the substances recovered from clogging the filter, which could
reduce engine performance.
YANMAR engines are equipped with a continuous regeneration system which filters harmful
substances using a DPF and to perform the regeneration without interrupting the operation of
the machine.
The soot accumulated in the DPF contains mainly metal components; it accumulates in large
amounts within the filter, but it can not be burned in the DPF. It is necessary to perform periodic
maintenance to remove the DPF soot accumulated in the filter.
IMPORTANT
To maintain optimal functioning of the DPF:
• Contact your dealer when the maintenance interval of the DPF is reached.
• Diesel fuel with sulphur levels of 15 ppm or less shall be used as fuel.
• A low ash oil must be used as engine oil.
15.1 Auto-regeneration
While using the machine at high speed or high load, harmful substances are systematically bur-
ned and removed.
15.2 Assisted regeneration
When the accumulation of pollutants reaches a certain level in the DPF, the engine's ECU in-
creases the exhaust gas temperature and automatically performs the regeneration of the DPF.
