Why EGR and intake systems foul
Unburned hydrocarbons in the exhaust can condense into sticky deposits. When these hydrocarbons combine with soot and recirculated exhaust gases, they can build up inside EGR valves, EGR coolers, intake manifolds and related components.
This can restrict airflow, affect EGR function and contribute to higher maintenance costs over time.
Combustion is the first control point
O3 Protegelo addresses the issue before deposits are created. By improving oxidation during combustion, it can reduce the amount of unburned HC and soot available to form sticky deposits.
Less unburned fuel means less material available to condense. This is why HC reduction is important for EGR and intake cleanliness.
Operational benefits
- Reduced unburned hydrocarbon emissions
- Lower soot and smoke formation
- Slower intake and EGR deposit build-up in suitable applications
- More stable airflow and combustion conditions over time
Relevant sectors
This is relevant for road fleets, vans, buses, GSE, construction machinery and any engine using EGR where low-load operation or high idle time contributes to deposit formation.
FAQ
Does O3 Protegelo clean an already blocked EGR valve?
No. Existing mechanical fouling may need maintenance. O3 Protegelo is intended to reduce the formation of new combustion by-products at source.
Why are HC and soot mentioned together?
Because unburned hydrocarbons can condense and mix with soot, creating sticky deposits that adhere to intake and exhaust components.
