8. CAUTIONS
1) Designated Engine Oil for CDPF (Low Ash Oil)
1. Need to use the designated engine oil for CDPF
- 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.
2. Advantages when using the designated engine oil for CDPF
- 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)
3. Problems when using non-designated engine oil for CDPF
- 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
1.
Producing white smoke during recycling
- The sulfur in exhaust gas is changed to sulfate gas during exhaust process. This sulfate
gas is shown as white smoke.
2. Producing odor during recycling
- The sulfur after oxidation may produce the odor.
3. Accumulation of ash
- 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.
1. Saturated vapor
2. Sulfate
