Precision-engineered for heavy-duty diesel engine operating conditions, the Caterpillar 355-6110 Electronic Unit Injector (EUI) is a critical fuel system component purpose-built for compatible CAT C15, C15 ACERT, and 3406E engine series. It delivers accurately metered, high-pressure fuel directly to the combustion chamber to support optimal combustion efficiency, consistent power output, improved fuel economy, and compliant emissions performance, and is manufactured to meet or exceed OEM specifications for reliable fit and function.

Constructed from high-strength alloy steel with OEM-level manufacturing tolerances, the 355-6110 injector features a precision-machined nozzle assembly, excellent wear resistance, and superior thermal stability to withstand harsh operating environments. Its electronically controlled metering ensures fine fuel atomization, supporting stable engine operation, reduced fuel consumption, lower exhaust emissions, and extended engine service life compared with worn or mismatched replacement units.

Validated for diverse industrial use cases, the injector fits heavy-duty highway trucks, construction machinery, mining equipment, marine vessels, generator sets, industrial power systems, oilfield equipment, and agricultural diesel devices. It is packaged in export-grade industrial packaging, comes with a 12-month warranty, and requires installation per OEM procedures, with injector seals and O-rings replaced during fitting to preserve performance and service life.
