Purpose-built for high-horsepower Caterpillar diesel assets operating in mission-critical environments, the 229-1631 Electronic Unit Injector (EUI) is a precision-calibrated OEM replacement component compatible with the full CAT 3500 engine family, including 3508, 3508B, 3512, 3512B, 3516 and 3516B configurations. It serves as a reliable fuel system solution for operators across industrial, power generation, marine, mining, oil and gas and rail sectors.
Equipped with electronically controlled fuel metering technology, the injector delivers highly accurate fuel quantities throughout the combustion cycle, paired with high-pressure injection capability to enhance spray penetration, atomization quality and combustion completeness. Every unit is calibrated to OEM-level standards, ensuring precise injection timing, consistent fuel delivery, cylinder-to-cylinder balance and stable engine performance, while lowering fuel consumption, particulate emissions and carbon deposits.
Its heavy-duty construction features hardened alloy steel bodies, precision-lapped valve assemblies, high-temperature resistant seals and wear-resistant nozzle components, engineered for extended service life under extreme operating conditions. The injector supports continuous duty cycles for demanding use cases, reducing unplanned downtime and total cost of ownership for equipment operators.
