DPF Heat Shield Science Trivia
Role:
Insulation: help DPF to reduce heat loss during high temperature regeneration and improve the efficiency of burning particulate matter.
Anti-scald: isolate the high temperature surface to avoid scalding or igniting the surrounding items during maintenance.
Protect parts: Protect nearby parts (e.g. wires, plastics) from being damaged by high temperatures.
Material: usually made of high-temperature resistant metal (such as stainless steel), some with heat-insulating coating.
Simply put: it is like the DPF “thermal insulation jacket”, both to protect the efficiency and safety! 🔥➡️🛡️
