White Smoke - SSANGYONG Rodius 2012.07 Manual

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
- The vehicle equipped with CDPF system may generate the white smoke when using the fuel
with high sulfur content (over 100 ppm). This is caused by the sulfur attached and
accumulated in CDPF. However, this is very natural situation, not caused by your vehicle.
- How to fix the problem
Replace current fuel with high grade fuel as soon as possible. How­ever, even after
replacing the fuel, the white smoke may be seen due to residual sulfur in CDPF system.
