1.Basic Information

Item	Details
Genuine Part Number	389-1969
Product Name	C-aterpillar Diesel Fuel Injector Assembly (Fuel Injector GP)
Fit Engine	CAT 3512B series diesel engines, compatible with 3512B-BEUI and 3512B-HD models
Application Equipment	Large generator sets, marine main engines, mining excavators, heavy construction equipment, oilfield equipment
Structure Type	Hydraulic Electronic Unit Injector (HEUI), precisely controlled by ECU, suitable for high-pressure fuel systems
Fuel Type	Low-sulfur diesel (meets ASTM D975 and EN 590 standards), compatible with National III / Euro III emission requirements

2. Technical Parameters

Item	Parameters
Operating Pressure	Fuel injection pressure: 28-32 MPa; Hydraulic control pressure: 10-14 MPa (suitable for 3512B original system)
Rated Fuel Injection Quantity	Single-cycle fuel injection quantity: 220-260 mm³ (meets original factory calibration, suitable for engine power requirements)
Flow Rate Deviation	Flow rate deviation of injectors in the same set ≤ ±1.5%, ensuring uniform engine power and stable fuel consumption
Net Weight	Approx. 1.6 kg (per unit); Gross Weight: Approx. 1.8 kg (including independent packaging)
Overall Dimensions	Length × Width × Height: 260 mm × 130 mm × 135 mm (measured dimensions, suitable for original installation position)
Operating Temperature	Ambient temperature: -40℃ ～ +135℃; Fuel temperature: -20℃ ～ +120℃
Mounting Torque	65-75 N·m (tighten according to original factory standards to avoid thread damage due to over-tightening or leakage due to under-tightening)
Electrical Parameters	Control voltage: 12V DC; Coil resistance: 2.8-3.2 Ω (meets ECU control specifications)

3. Structure & Material

Item	Details
Body Material	High-strength forged alloy steel shell,经过 quenching and tempering treatment, tensile strength ≥ 800 MPa, impact-resistant and corrosion-resistant
Plunger & Barrel	Tungsten-chromium alloy material, precision ground and paired, fit clearance ≤ 0.002 mm, wear-resistant, extending service life
Nozzle Assembly	Multi-hole nozzle (6-8 spray holes), made of high-temperature resistant hard alloy, spray hole precision ≤ 0.01 mm, uniform atomization effect
Sealing Structure	Dual sealing design: Upper O-ring rubber seal (oil-resistant and high-temperature resistant), lower red copper gasket (excellent sealing performance, preventing fuel leakage)
Control Assembly	Imported solenoid valve core, response time ≤ 5ms, sensitive action, ensuring accurate injection timing and adapting to all engine operating conditions
Surface Treatment	Cathodic electrophoresis + anti-rust coating, salt spray test ≥ 48 hours, effectively resisting moisture and oil pollution corrosion, adapting to harsh working environments
