Why DPFs become overloaded
DPF loading is not only a simple soot issue. In real operation, unburned hydrocarbons can condense and mix with soot, creating sticky, wet deposits that increase backpressure and make regeneration more difficult.
Low-load operation, excessive idling, stop-start cycles and poor combustion all increase the amount of unburned fuel and soot entering the exhaust system.
The objective is to reduce the material reaching the DPF. O3 Protegelo improves combustion before the exhaust gases enter the filter.
How O3 Protegelo helps reduce DPF stress
By improving oxidation of the fuel during combustion, O3 Protegelo can reduce unburned hydrocarbons, CO and soot formation. This can help reduce the rate at which the DPF loads under suitable operating conditions.
- Less soot formation at source
- Lower unburned HC entering the exhaust
- Reduced condensation-related deposit formation
- Longer intervals between active regeneration in suitable applications
- Reduced thermal stress from repeated regeneration cycles
Important clarification
O3 Protegelo is not a DPF cleaning machine and does not replace maintenance for a blocked or damaged filter. Its value is in reducing the combustion by-products that contribute to future loading.
Best-fit applications
Urban trucks, buses, delivery fleets, construction equipment, port machinery, GSE and generators often experience low-load or idle-heavy cycles that make DPF problems worse.
FAQ
Can O3 Protegelo reduce active regeneration frequency?
In suitable applications, reducing soot and HC formation can reduce the rate of DPF loading, which may extend the interval between active regenerations.
Should it be installed before or after the fuel filter?
For most applications, installation after the main fuel filter on the low-pressure fuel feed line is preferred.
