Off-Road Construction and Mining
Diesel oxidation catalysts and particulate filters for off-road construction and mining equipment, where duty cycles are long and regeneration management matters.
Industry Pain Points
What Makes This Application Hard
- Off-road diesel equipment emits black smoke, hydrocarbons and soot that have to be removed from the exhaust.
- As the accumulated particulate layer becomes thicker, pressure loss increases and engine performance suffers.
- Different displacement standards apply to different markets and machine classes.
What PRT Publishes
Capability Statements from the Catalogue
- The DOC substrate is specifically developed for emission control from on-road vehicle application to off-road construction or mining application.
- The system installed with DPF has been examined for urban bus, forklift, truck and mining constructing equipment.
- SiC DPF carbon particulate filtration efficiency is more than 90 percent.
- Systematic DPF designs are available upon customers' requirements so as to reach the demands of different displacement standards.

FAQ
Frequently Asked Questions
Which engine sizes are covered?
Diesel Oxidation Catalysts cover from 0.1 liters to 25 liters as a single DOC, suiting diesel engine displacement from 0.5 to 25 liters. DPF volumes run from 1.0 liters to 43 liters.
How is the filter regenerated?
Regeneration burns the accumulated particulate by raising the gas temperature of the filter. The ash left after regeneration should be cleaned regularly.
Can the system be designed around our machine?
Systematic designs are available upon customers' requirements to reach the demands of different displacement standards.
