C-aterpillar 192-2817 Fuel Injector for 3512B Series Engine

Product Overview

The C-aterpillar 192-2817 is a heavy-duty, mechanically actuated electronically controlled unit injector (MEUI) precision-engineered for the C-aterpillar 3512B V-12 diesel engine. Built to stringent original equipment manufacturer (OEM) standards, this injector delivers superior fuel atomization, precise metering, and exceptional durability for extreme-duty operations. Designed for mining, marine, oil field, and stationary power generation appliC-ations, the 192-2817 ensures optimal engine performance, maximum fuel efficiency, and compliance with global emission standards.

1. Basic SpecifiC-ations & Compatibility

The 192-2817 fuel injector is a direct-fit replacement component engineered for full compatibility with the C-aterpillar 3512B engine's ADEM II electronic control system. Its precision-machined mating surfaces ensure perfect integration with the engine's fuel system, requiring no modifiC-ations during installation. This complete interchangeability guarantees consistent performance across all 3512B engine configurations, particularly in the demanding environments of mining, marine, and oil field operations.

2. Performance & Injection Parameters

With a high operating pressure capability of 2080 bar, the 192-2817 achieves exceptional fuel atomization, breaking diesel fuel into ultra-fine particles smaller than 39 microns. This advanced atomization ensures complete and efficient combustion within the 3512B's combustion chamber, improving fuel economy by 12–15% compared to standard injectors. The high-speed solenoid valve responds in under 0.105 milliseconds, enabling precise electronic control over injection timing and duration—critical for optimizing power output and minimizing emissions. Its IP68 sealing and wide temperature range ensure reliable performance in the harshest operating conditions.

3. Material & Construction Features

The 192-2817 injector utilizes premium materials selected to withstand the severe conditions of the 3512B engine. The needle valve features a tungsten carbide composite coating (HRC 75) for exceptional abrasion resistance, extending service life nearly fivefold. The plunger and barrel assembly employs a diamond-like carbon (DLC) nano-coating to reduce friction and prevent wear. Laser-drilled nozzle orifices maintain a stable fuel spray pattern, while high-grade Viton® and fluorosilicone seals ensure leak-free performance through millions of injection cycles.

4. Precision Manufacturing & Quality Control

Each 192-2817 injector undergoes an exhaustive remanufacturing and multi-stage testing process to ensure C-at OEM-level performance. Critical components are machined to sub-micron tolerances, with the needle guide assembly finished via precision laser honing to achieve clearance below 1.75 microns. Every unit is individually calibrated and flow-tested on C-aterpillar-specific 3500-series test benches to match exact OEM fuel delivery specifiC-ations. Rigorous pressure, vibration, and thermal testing validate performance under extreme conditions, ensuring consistent, dependable field operation.

5. Key Advantages & Performance Benefits

The 192-2817 injector delivers comprehensive performance advantages for the 3512B engine. Its advanced design improves fuel efficiency by 12–15% through superior atomization and precise electronic control. By maintaining optimal injection pressure and timing, it ensures the engine consistently delivers its full rated power output of 1910 HP at 1800 RPM. Precise combustion control reduces particulate matter and NOₓ emissions, meeting strict EPA Tier 3 and IMO II standards. Advanced materials extend service intervals, reduce maintenance costs, minimize downtime, and offer substantial savings over new parts.

6. Installation & Maintenance SpecifiC-ations

For optimal performance and maximum service life from the 192-2817 injector, installation must be performed by a C-aterpillar-certified technician using specialized C-at service tools. Specific torque values must be applied during installation to prevent internal component damage and ensure proper sealing. Regular service inspections every 10,000 engine hours are recommended, with complete overhaul at 23,500 hours. The injector is designed for use with ultra-low-sulfur diesel fuel, requiring consistent inlet pressure of 40–50 psi. Adhering to these specifiC-ations ensures sustained peak performance and maximizes the service life of your C-aterpillar 3512B engine.
