LI3
Common rail injector
Developed specifically for large diesel engine applications in mining, rail, marine and power generation, the LI3 common-rail injector is designed for demanding operating conditions depending on the application. The design aims to minimise control leakage and can therefore contribute to efficient operation. The double-walled housing, flat-seat control valve and coated components help protect against the fuel-related, application-specific and environmental stresses that occur in the respective application. Depending on the system design, an integrated pressure accumulator enables operation without a separate rail and can help reduce pressure losses. The LI3 is available with various housing configurations and nozzle variants. The LI3 injector is certified in accordance with DNV marine standards.
