System Monitoring

DE-TRONIC features smart back-pressure, temperature profile and regeneration monitoring.

SLI (Soot Load Index) is the result of complex calculations based on the pressure drop over the filter system compared to the exhaust gas flow through it.

The major advantage of using the SLI is that DE-TRONIC can measure the Soot Load of the DPF System under all operating conditions.

A running average of the SLI is displayed on the dashboard indicator

The Thermal Counter is derived from the temperature at the inlet of the filter system and triggers the catalytic activity in the DPF.

For passive systems DE-TRONIC will show a warning if the regeneration of the filter cannot be guaranteed due to too low a temperature.

For active systems a low Thermal Count combined with a high SLI will launch the active regeneration procedure.
