For fleet operators and equipment managers sourcing dependable fuel system components, the Caterpillar 20R-2285 fuel injector offers an OEM-specification solution engineered for the Caterpillar C15, C15 ACERT, C16, and 3406E diesel engine platforms. Operating within the Electronic Unit Injection (EUI) system, this injector assembly serves on-highway and off-highway applications, including heavy-duty highway trucks, mining trucks, construction excavators, wheel loaders, generator sets, marine vessels, and oilfield power units.

Actuated electronically by the engine control module, the 20R-2285 delivers precisely metered, high-pressure fuel through a precision nozzle, producing fine fuel atomization for optimized combustion. The result is improved combustion efficiency, lower fuel consumption, reduced particulate emissions, and enhanced engine power output. Manufactured to OEM specifications, the injector incorporates wear-resistant internal components and a corrosion-resistant injector body, ensuring a long operational lifespan under demanding operating conditions across construction, mining, marine, and power generation sectors.

For dependable service, installation should follow Caterpillar torque specifications with all seals and O-rings replaced, followed by fuel system bleeding and an injector cutout test. Routine maintenance using premium diesel fuel and regular fuel filter replacement helps prevent hard starting, black or white smoke, rough idle, and reduced power. Cross reference numbers include 10R-1273, 10R1273, 253-0618, and 2530618; verification by engine serial number is recommended. We support B2B buyers with MOQ from one piece, competitive wholesale pricing, fast global shipping, and technical support.
