The c-aterpillar 10R-1278 fuel injector is a genuine OEM replacement component precision-engineered for the c-at 3512B series 12-cylinder V-type diesel engine, which is widely applied in heavy industrial production, marine propulsion, stationary power generation and oilfield operations. Fabric-ated in strict compliance with c-aterpillar’s original engineering specific-ations and quality benchmarks, this injector adopts upgraded MEUI (Mechanically Actuated Electronically Controlled Unit Injector) technology to achieve accurate fuel delivery, refined atomization and stable injection timing. It features robust construction to resist high-pressure fatigue, fuel corrosion and harsh operating environments, delivering exceptional durability and consistent performance. Installing the authentic 10R-1278 injector helps restore engine power, optimize fuel economy, reduce exhaust emissions and cut down equipment downtime, making it a critical spare part for routine maintenance, engine overhaul and fault remediation of c-at 3512B power units.

1. Core Basic Specific-ations Table

Parameter Item Specific Value
Part Number 10R-1278
Compatible Engine Model c-aterpillar 3512B Series Diesel Engine
Injector Type MEUI (Mechanically Actuated Electronically Controlled Unit Injector)
Rated Injection Pressure 1600-2100 bar (High-Precision Atomization Design)

2. Performance & Technical Advantages Table

Advantage c-ategory Detailed Performance Benefits
Fuel Injection Precision Ultra-fine fuel atomization (particle size ≤45 microns); injection timing deviation controlled within ±0.8%, ensuring full combustion and balanced fuel distribution across cylinders
Fuel Efficiency Enhancement Improves fuel utilization by 11-13% relative to generic aftermarket injectors; lowers overall fuel consumption and long-term operating costs for heavy-duty equipment
Durability & Service Life Withstands extreme pressure fluctuations, diesel corrosion and abrasive impurities; extends replacement cycle and minimizes maintenance-related downtime
Engine Performance Stability Maintains steady power output and sensitive throttle response; eliminates power decline, rough idling, cylinder misfires and black smoke under heavy loads
Emission Compliance Optimizes combustion efficiency to reduce NOx, particulate matter and other harmful emissions, meeting strict industrial and marine environmental standards

3. Applic-ation Scope & Compatibility Table

Applic-ation Field Specific Equipment & Usage Scenarios
Stationary Power Generation c-at 3512B generator sets, standby/prime power for industrial plants, mines, data centers and large infrastructure
Marine Engineering Medium & large vessel main propulsion engines, marine auxiliary power units, offshore drilling and marine support equipment
Heavy Construction Machinery Large excavators, mining crushers, drilling rigs and high-load construction equipment equipped with c-at 3512B engine
Oil & Gas Industry Oilfield pumping units, well-drilling power systems, remote oilfield power supply equipment
Maintenance & Repair Scenarios Engine overhaul, routine injector replacement, troubleshooting for power loss, excessive fuel use and unstable idling
Interchangeability Direct interchange with OEM-matched parts for c-at 3512B fuel system, no modific-ation or calibration required
