Common Rail Systems for Marine Propulsion Engines
HEINZMANN Common Rail Systems enable propulsion engine manufacturers and fleet operators to leverage the benefits of common rail technology. The particular safety requirements are met both by their classified controllers and their double-walled hydraulic components. Particularly with HFO operation, reliability of HEINZMANN components is ensured thanks to a proven design and the highest manufacturing quality standards. Along with tailored monitoring and safety devices, as well as flexible interfaces, a complete engine management system is offered. As a result of the precise control, marine propulsion engines operate more smoothly with lower fuel consumption and emission levels.

HDP-K3 HFO |
High-pressure pump with 3 pressure elements for system pressures up to 2,200 bar. Delivery rates up to 15 l/min (1 pump) / redundant concept: up to 30 l/min (2 pumps). Designed for heavy fuel oil operation, featuring a special two-way HFO/lube-oil sealing concept, mix oil drain and high-temperature resistant design. |
HDP-K4 HFO |
High-pressure pump with 4 pressure elements for system pressures up to 2,400 bar. Delivery rates up to 65 l/min (1 pump) / redundant concet: up to 130 l/min (2 pumps). Designed for heavy fuel oil operation, featuring a special two-way HFO/lube-oil sealing concept, mix oil drain and high-temperature resistant design. |
Solenoid-controlled Fuel Injectors
Thanks to their static leak free design, the ICR-DS fuel injectors reduce fuel backflow by 75% compared to conventionally designed, leakage afflicted injectors. Peak pressures were diminished by 25% through the integration of an accumulation volume (rail volume). As a result, a smooth fuel flow can be achieved, which is of highest importance especially for heavy fuel oil (HFO) operation.
