Engineered as a precision fuel system component for Caterpillar C9.3 engine platforms, the 20R-5078 original new common rail diesel injector is manufactured strictly to OEM specifications. It is compatible with all documented C9.3 variants: 250-340 HP industrial diesel engines, 250-375 HP C9.3B units, 275-380 HP ACERT models, 250-350 kW generator drive engines, and 300-375 HP marine propulsion engines.
Built with hardened alloy steel and a multi-hole precision nozzle, the injector supports operating pressures up to 2000 bar for direct injection in high-pressure common rail systems. Regulated by the engine’s electronic control module, it delivers precisely timed, finely atomized fuel to optimize combustion efficiency, improve fuel economy, reduce smoke and particulate emissions, speed throttle response, and maintain stable idle, while its corrosion-resistant coating extends service life and reduces maintenance costs.
This industrial-grade injector is qualified for use across construction, mining, power generation, and marine sectors, fitting excavators, wheel loaders, motor graders, compactors, DE-series generator sets, industrial power units, and marine systems. It is backed by a 12-month warranty, and standardized installation and maintenance guidelines are available to minimize unplanned equipment downtime and ensure consistent long-term performance.
