Dongfeng Renault engine parts Fuel injector rear wiring harness assembly 3610312-E9301

Engineered to deliver stable, interference-free signals between the ECU and fuel injector s, the harness uses twisted-pair wires with aluminum-mylar shielding (95% coverage). This shielding blocks electromagnetic interference (EMI) from engine components (e.g., alternators, ignition coils) and radio frequency interference (RFI) from vehicle electronics—critical for preserving the ECU’s precise control signals (e.g., injection pulse width, timing). Each wire is made of 18 AWG tinned copper (stranded for flexibility) that ensures low resistance (≤ 0.05Ω/m) and efficient current transfer, even in low temperatures (-40°C). Unlike unshielded harnesses that suffer signal degradation, this design maintains signal integrity within ±1% accuracy, ensuring fuel injector s receive exact ECU commands for optimal fuel atomization and combustion efficiency

Built to withstand the harsh thermal and chemical environment of Dongfeng Renault’s engine bay, the harness features a dual-layer jacket. The inner layer is made of cross-linked polyethylene (XLPE) that resists temperatures up to 125°C, while the outer layer is a flame-retardant polyvinyl chloride (PVC) (UL94 V-0 rating) that endures 150°C peak temperatures (e.g., near exhaust manifolds). The jacket also repels engine oil, diesel fuel, coolant, and road salt—preventing swelling (volume increase ≤ 3% after 1,000 hours of oil immersion) or cracking. Unlike standard PVC jackets that harden in high heat, this dual-layer design retains flexibility through 10,000+ thermal cycles (-40°C to 125°C), ensuring the harness remains durable and easy to route during maintenance

To prevent connector failure (a leading cause of fuel injector malfunctions), the harness integrates high-quality OEM-compatible connectors and strain relief features. Each connector is made of glass-filled nylon (PA66-GF30) that resists impact and heat, with gold-plated pins (50μm thickness) that ensure low-contact resistance (≤ 10mΩ) and corrosion resistance. The connectors include a locking tab design that secures them to the ECU and fuel injector s, preventing vibration-induced disconnection. Additionally, each wire entry point features a rubber boot that provides strain relief, absorbing stress from engine vibration and preventing wire breakage at the connector. Unlike low-quality connectors that corrode or loosen, this design ensures reliable electrical contact for 100,000+ km of operation

Designed for efficient replacement in repair shops, the harness simplifies installation with user-friendly features. It includes pre-attached mounting clips that match the engine’s factory bracket positions, allowing technicians to secure the harness without drilling. The wires are color-coded (per Dongfeng Renault’s standard) and labeled at each connector, eliminating guesswork during installation. Installation takes 45–60 minutes with standard hand tools—no specialized crimping or soldering required. To guarantee performance, each harness undergoes strict testing: continuity checks (100% pin-to-pin verification), insulation resistance testing (≥ 100MΩ at 500V DC), EMI/RFI shielding effectiveness testing, and environmental durability trials (temperature, humidity, vibration). Backed by a 24-month warranty against manufacturing defects (e.g., wire breakage, connector corrosion, or shielding failure), it provides Dongfeng Renault engine owners with reliable fuel injector control and long-term engine performance
