Roadwarrior C0326-HF - Diesel Oxidation Catalyst (DOC) and Particulate Filter (DPF) Assembly for Hino

Features & Benefits

• Limits unexpected derates tied to slow or incomplete regeneration
• Supports better soot control during extended idle-heavy operation
• Helps minimize exhaust backpressure buildup during long service intervals
• Can help extend DEF system efficiency by reducing soot load upstream
• Promotes steadier exhaust temperature profiles during heavy load cycles

Roadwarrior Diesel Oxidation Catalyst (DOC) and Particulate Filter (DPF) Assembly

The Roadwarrior Diesel Oxidation Catalyst (DOC) and Particulate Filter (DPF) Assembly gives Hino trucks a highly active emissions component that supports passive regeneration more effectively. Catalyst coating quality directly affects how efficiently soot oxidizes, and degraded coatings often force the ECU to trigger additional active regens. This assembly offers a properly coated DOC-to-DPF interface, helping reduce unnecessary fuel use associated with excessive regeneration cycles. The Roadwarrior C0326-HF serves fleets that want to cut down on regen-related downtime and maintain cleaner emissions performance across longer routes.
