Caterpillar original 20R-8047 Fuel Injector 10R-7229 Replacement for OEM 20R-2284 for Caterpillar C15 Engine, Excavator Application, Cross Reference 253-0615 original new injector

For fleet operators, equipment maintenance teams and industrial engine parts distributors sourcing reliable replacement injection components, the Caterpillar 20R-8047 fuel injector delivers OEM-grade performance for heavy-duty Caterpillar engine platforms. As a direct-fit replacement, it is compatible with all C15 variants (including ACERT, industrial, marine and generator models), C16 and 3406E engines, and cross-references to 10R-0955 (10R0955) and 249-0713 (2490713) for streamlined part matching. It supports a wide range of heavy-duty equipment, from highway trucks and construction machinery to marine engines, generator sets and oil & gas equipment.

Adopting electronic MEUI injection technology, the 20R-8047 works in tandem with the engine’s ECM to execute precise fuel metering, high-pressure atomization and optimized spray patterns, effectively improving combustion efficiency. Its verified operational benefits include enhanced fuel economy, reduced exhaust emissions and black smoke, faster throttle response, smoother idle and better cold-start performance, helping operators cut fuel costs and meet emission standards under harsh working conditions.

Manufactured in strict compliance with original Caterpillar engineering specifications, the injector uses corrosion-resistant, durable internal components and passes factory performance tests to deliver long service life and reliable heavy-duty operation in extreme environments. Following official Caterpillar installation and maintenance guidelines, such as replacing seals during fitment and using clean diesel and OEM-quality filters, maximizes its service life and reduces unplanned equipment downtime for industrial clients.
