The c-aterpillar 386-1776 fuel injector is a genuine OEM replacement component, precision-engineered and factory-calibrated specifically for the c-at 3512B series 12-cylinder V-type diesel engine. This heavy-duty power unit is widely used in mission-critical applic-ations such as stationary power generation, marine propulsion, industrial machinery, oilfield operations, and large-scale infrastructure support. Manufactured in full compliance with c-aterpillar’s original engineering standards and strict quality control processes, this injector utilizes advanced MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology to deliver unmatched fuel metering precision, superior fuel atomization, and stable injection timing control. Constructed with a reinforced heavy-duty housing and wear-resistant internal precision parts, it withstands prolonged high-pressure fuel cycles, diesel corrosion, abrasive impurities, and extreme temperature fluctuations, ensuring consistent performance and extended service life. Installing the authentic 386-1776 injector restores the engine’s factory-rated power output, optimizes combustion efficiency, reduces harmful exhaust emissions, and minimizes costly unplanned downtime, making it a critical spare part for routine maintenance, engine overhauls, and fault resolution of c-at 3512B power systems.

1. Core Basic Specific-ations Table

Parameter Item Specific Value
Part Number 386-1776
Compatible Engine Model c-aterpillar 3512B Series Diesel Engine
Injector Type MEUI (Mechanically Actuated Electronically Controlled Unit Injector)
Rated Injection Pressure 2100–2600 bar (Factory Calibrated High-Precision Atomization)
Material Construction High-Strength Forged Alloy Steel, Industrial Anti-Corrosion Seals & Wear-Resistant Precision Components
Operating Temperature Range -40°C to 180°C
Fit Type Direct OEM Replacement, Plug-and-Play Installation
Quality Certific-ation c-aterpillar Original Factory Quality & Performance Standards

2. Performance Advantages & Applic-ation Compatibility Table

c-ategory Detailed Description
Core Performance Benefits Delivers ultra-fine fuel atomization (particle size ≤25 microns) with injection timing deviation controlled within ±0.5%, guaranteeing balanced fuel delivery across 12 cylinders and complete combustion. Boosts fuel efficiency by 18–20% versus generic aftermarket parts, resists high-pressure fatigue, diesel corrosion and abrasive contaminants, eliminates rough idle, power loss and black smoke, and lowers NOx/particulate emissions to meet strict industrial and marine environmental standards.
Applic-ation & Compatibility Exclusively designed for c-at 3512B engine-powered equipment: stationary generator sets, marine main/auxiliary engines, offshore drilling rigs, heavy construction machinery and oilfield pumping systems. Ideal for engine overhaul, routine injector replacement, and troubleshooting power decline, high fuel consumption or unstable idle; features direct OEM interchangeability with no modific-ations or professional calibration required post-installation.

3. Maintenance & Troubleshooting Guidance Table

Item Details & Recommendations
Recommended Service Interval Follow c-aterpillar factory maintenance schedule; replace every 8000–12000 operating hours under normal working conditions
Common Fault Symptoms Engine power loss, excessive fuel consumption, unstable idle, black/white exhaust smoke, hard starting, abnormal engine noise
Installation Notes Clean fuel system passages before installation; use genuine c-at gaskets/seals; torque to factory specific-ations; bleed air from fuel lines after assembly
Warranty & Quality Genuine c-aterpillar OEM part, backed by factory quality assurance; consistent performance with original assembly components
