Compatible with Delphi HDU Series Piezo Diesel Fuel Injector 20440388 – For Volvo D13A / Caterpillar C9 Generator

The product compatible with Delphi 20440388 fuel injector from the HDU Series is engineered for heavy-duty marine auxiliary power and generator applications—including the Volvo D13A marine engine and Caterpillar C9 generator sets—and is compliant with the IMO Tier II emission standard. This injector features a heavy-duty salt-corrosion-resistant design, validated by a rigorous 2,000-hour salt spray certification, ensuring reliable operation in harsh marine environments where exposure to salt and moisture is inevitable. It also supports a wide voltage operating range of 9-36V, allowing stable performance amid fluctuating shipboard electrical systems. With precise fuel metering maintaining injection quantity variation within ±1.5%, the piezo actuator delivers rapid and accurate fuel delivery. This results in improved combustion efficiency, reduced emissions, and enhanced engine reliability under demanding operating conditions. The multiple injection capability also contributes to lower engine noise and vibration, enhancing overall operational smoothness.
