Introduction
The 260x227mm Silicon Carbide (SiC) Diesel Particulate Filter (DPF) from KSRCAT represents a cutting-edge solution for modern diesel emissions control. Designed for universal compatibility across engine types, this filter combines superior thermal resistance with high filtration efficiency. Below is a detailed breakdown of its features, applications, and advantages—presented entirely in descriptive text without tables.
1. Product Overview
Material & Construction
This DPF is crafted from silicon carbide (SiC), a material chosen for its exceptional properties:
Melting point up to 1400°C, far exceeding traditional cordierite filters (1200°C).
Thermal shock resistance ensures durability under rapid temperature changes.
Precision engineering with ±0.1mm dimensional tolerance and uniform pore distribution for optimal soot capture.
Key Specifications
Dimensions: 260mm diameter × 227mm height.
Cell Density: Configurable at 200 or 300 cells per square inch (CPSI).
Wall Thickness: 0.35–0.41mm, balancing flow efficiency and particulate retention.
Porosity: 42–60%, enhancing filtration capacity.
Capture Rate: Exceeds 95% for particulate matter (PM).
2. Applications
This SiC DPF is engineered for diverse diesel-powered systems:
Automotive: Compliant with Euro 5/6 standards, ideal for passenger vehicles and light-duty trucks.
Heavy-Duty Transport: Suitable for DAF, Volvo, and Scania trucks, especially models sensitive to backpressure (10–13 kPa range).
Industrial & Marine: Resists chemical corrosion in harsh environments like construction equipment or ship engines.
Custom Solutions: Available with precious metal coatings (PT/3gr ft³ to PT/20gr ft³) for passive regeneration.
3. Performance Advantages
Compared to Cordierite DPFs
Silicon carbide filters outperform cordierite in critical areas:
Thermal Stability: SiC handles temperatures up to 1400°C without structural degradation, while cordierite risks failure at 1200°C.
Filtration Efficiency: SiC achieves >95% PM capture versus ~85% for cordierite.
Longevity: Resistant to thermal cracking and chemical wear, reducing replacement frequency.
Operational Benefits
Low pressure drop minimizes engine backpressure, preserving fuel efficiency.
Passive regeneration (with coatings) burns soot at lower temperatures (250–350°C), reducing fuel consumption.
Active regeneration (uncoated versions) requires higher temps (550–650°C) but remains reliable under heavy loads.
4. Technical Insights
Regeneration Mechanisms
Coated Filters: Use platinum/palladium catalysts to oxidize soot passively, ideal for urban driving with frequent stops.
Uncoated Filters: Depend on active regeneration via engine ECU-controlled high-temperature cycles, suited for highway use.
