NTA855
KING POWER
8409919990
Compatibility & Application
Engine Model: Specifically engineered for Cummins NTA855 biogas engines, ensuring seamless integration with cylinder bore dimensions and piston groove specifications.
Fuel Type: Optimized for biogas (methane-rich fuels), including landfill gas, sewage gas, and agricultural waste-derived fuels, withstanding corrosive combustion byproducts.
Applications: Industrial cogeneration plants, renewable energy farms, waste-to-energy facilities, and standby power systems requiring reliable biogas-fueled operation.
Material & Construction
Compression Rings: High-grade cast iron alloy with plasma-coated surfaces to resist wear, scoring, and micro-welding under high-pressure combustion.
Oil Control Rings: Multi-layered stainless steel with chrome-nitride plating for enhanced oil scraping efficiency and reduced blow-by.
Tensile Strength: Engineered to withstand peak cylinder pressures up to 200 bar while maintaining dimensional stability.
Performance Features
Sealing Efficiency: Advanced taper-face and barrel-face designs minimize gas leakage, improving thermal efficiency by 5–8% compared to standard rings.
Oil Consumption: Reduces lubricant usage by 30–40% through precision-engineered oil return channels, lowering maintenance costs.
Thermal Resistance: Operates effectively at temperatures up to 450°C (842°F), preventing ring sticking or carbon buildup in biogas combustion chambers.
Quality Assurance
ISO 9001:2015-certified manufacturing process with 100% dimensional inspection using CMM technology.
Salt spray testing (ASTM B117) ensures corrosion resistance in humid or acidic biogas environments.
Endurance testing: 1,000+ hours of simulated biogas operation without seal degradation.
Installation & Maintenance
Kit Includes: 3 compression rings (top, intermediate, second) and 1 oil control ring per cylinder, pre-lapped for immediate fitment.
Gapping Specifications: Factory-set end gaps optimized for NTA855 cylinder bore expansion rates (0.35–0.45mm at operating temperature).
Replacement Interval: Recommended every 8,000–10,000 hours or as part of scheduled engine overhauls.
Environmental & Compliance
Meets EU Stage V and EPA Tier 4 Final emission standards for biogas engines when paired with OEM catalytic converters.
RoHS-compliant materials eliminate hazardous substances, ensuring safe disposal or recycling.
Packaging & Logistics
Anti-corrosion packaging with VCI (Vapor Corrosion Inhibitor) film and shock-absorbent foam inserts.
Lead time: 15–20 days for bulk orders (MOQ: 50 sets), with express shipping options for urgent replacements.
Cross-Reference: Direct replacement for OEM part 4089810-20 and aftermarket equivalents (e.g., 4089810RX, 4089810-20HD).
Warranty: 18-month limited warranty against manufacturing defects, covering premature wear or seal failure under normal operating conditions.
This product combines precision engineering with biogas-specific durability, offering NTA855 operators a cost-effective solution to maximize engine uptime and fuel efficiency in renewable energy applications.
