8. CAUTIONS
1) Designated Engine Oil for CDPF (Low Ash Oil)
Need to use the designated engine oil for CDPF 1.
The smoke from the vehicle may generate the particle material in the ambient air. CDPF is the
device to reduce the smoke by collecting and recycling it. To ensure the performance of CDPF,
the designated engine oil should be used.
The smoke including combusted sulfur in fuel cannot be recycled in CDPF. This smoke
generates the ash, resulting in clogging the filter. -
-
Advantages when using the designated engine oil for CDPF 2.
Reduces the amount of ash
Improves the fuel economy and reduces the CO2
Increases the life span of engine oil
Available for all engines (diesel and gasoline) -
-
-
-
Problems when using non-designated engine oil for CDPF 3.
Decreases the life span of engine oil due to accumulated ash in DPF (around 30%)
Decreases the fuel economy due to friction resistance, exhaust gas resistance and frequent
recycling process of DPF -
-
The fule containing high sulfur may cause the same problems.
2) Do Not Use the Fuel Containing High Sulfur
Producing white smoke during recycling 1.
The sulfur in exhaust gas is changed to sulfate gas during exhaust process. This sulfate gas is
shown as white smoke. -
Producing odor during recycling 2.
The sulfur after oxidation may produce the odor. -
Accumulation of ash 3.
The sulfur accumulated in DPF cannot be recycled. It reduces the life span of DPF. -
3) White Smoke
The white smoke can be generated when the exhaust gas is recycled in DPF. There are two reasons as
below.
Saturated vapor
Sulfate 1.

Display regeneration history (distance/time)
stored until now in figure, Index ([0] ~ [4])
The regeneration distance/time is stored up
to the last 5 events in sequence and the
oldest one will be deleted if the number of
events is exceeded 5 times.
The currently displayed index value indicates
where the regeneration information will be
stored in the future and the just previous
value shows the last regeneration
information.

No. Sensor item Data Unit Unit
20 Times of CDPF regeneration
start (soot mass from engine)0 - The ECU calculates the soot mass from
engine in consideration of the engine RPM,
based on the ECU base MAP. The ECU
regenerates the CDPF automatically when it
determines that the accumulated soot is
about 36 g or greater. (The more city driving,
the greater value is) The times of
regeneration is displayed cumulatively.
21 Times of CDPF regeneration
start (collected soot mass)0 - The ECU calculates the soot mass from
engine in consideration of the engine RPM,
based on the ECU base MAP. The ECU
regenerates the CDPF automatically when it
determines that the accumulated soot is
about 24 g or greater. (The more city driving,
the greater value is) The times of
regeneration is displayed cumulatively.
22 Times of CDPF regeneration
start (driven distance)0 - The ECU regenerates the CDPF
automatically when the driving distance
reaches about 1,000 km or longer. (The
more high-speed driving, the greater value is)
The times of regeneration is displayed
cumulatively.
23 Times which CDPF re-
regeneration start is
requested0 - When the regeneration should be stopped
and started again according to the exhaust
gas temperature, start condition and vehicle
speed during CDPF regeneration, the times
of re-regeneration is displayed cumulatively.
24 Times which SIW forced
CDPF regeneration is
requested0 - The times which the technician carried out
the forced regeneration using the SIW
program is displayed cumulatively.
25 Times of ECU replacement 1 - The times of ECU initialization is displayed
cumulatively.
The ECU calculates the data of 4 items from No. 19 to No. 22 (map value calculated by the ECU) to
carry out the CDPF regeneration and the regeneration event map values of 4 items between No. 19
to No. 22 will be reset. (times of regeneration start is stored normally)
In the event of ECU initialization, the data of items from No. 1 to No. 24 will be reset. A.
