Dongfeng Engine assembly auto parts wiring harness assembly 3610310-E85N0

Built as the "nerve system" of the engine, this wiring harness features high-performance conductive materials to guarantee stable signal and power transmission. The core wires are made of oxygen-free copper (OFC) with 99.9% purity, offering a conductivity of 58 MS/m—3% higher than standard copper wires. This minimizes voltage drop (≤0.1V at 10A current) and ensures accurate signal transmission between the ECU and sensors, critical for precise fuel injection control. The wire strands are twisted (7×19 structure) to enhance flexibility, allowing 10,000+ bending cycles without breakage. Each wire is color-coded and labeled per Dongfeng’s standard, simplifying maintenance and avoiding wiring errors that cause engine misfires or ECU damage

Engineered to resist extreme conditions in the engine bay, the 3610310-E85N0 harness adopts a comprehensive protective system. The wires are insulated with cross-linked polyethylene (XLPE) material, which withstands continuous temperatures of 125℃ (short-term 150℃) and resists oil, coolant, and diesel corrosion. The outer sheath uses flame-retardant polypropylene (FRPP) with a thickness of 1.2mm, achieving UL94 V-0 flame rating and IP67 water/dust resistance. Critical sections (near exhaust manifold) are reinforced with fiberglass braiding for additional heat protection. The connectors feature PA66 housings and nitrile rubber seals, preventing moisture ingress and ensuring a secure fit with a mating force of 8-12N, passing 500+ insertion/extraction cycles without failure

Optimized for long-term reliability under engine vibration, the harness integrates vibration-dampening and secure routing features. It uses flame-retardant cable ties (PA66) with stainless steel locking teeth to fix the harness to the engine’s mounting brackets, eliminating movement that causes abrasion. Rubber grommets (EPDM) are installed at penetration points (engine cover, firewall) to absorb 60% of engine vibration (10-500Hz) and prevent sheath wear. The harness’s routing path is designed to avoid contact with hot components (exhaust manifold, turbocharger) with a minimum clearance of 50mm, and away from moving parts (timing belt, pulleys) to prevent entanglement. These design elements reduce harness failure due to vibration or abrasion by 75%

This wiring harness assembly is designed for efficient installation and long-term cost savings for Dongfeng engine operators. The pre-assembled structure (wires + connectors + grommets + cable ties) comes with a routing template, allowing a single technician to complete installation in 90 minutes—no wire cutting or terminal crimping required. The OE-compatible design eliminates compatibility issues common with aftermarket harnesses, which often cause electrical shorts or sensor malfunctions (repair costs up to $1,800). The high-quality materials extend the harness’s service life to ≥600,000km—three times that of generic harnesses—reducing replacement frequency. Backed by a 2-year/300,000km Dongfeng warranty, it ensures reliable engine electrical performance and predictable maintenance expenses for fleets
