HEINZMANN - Experts for marine applications

HEINZMANN provides turnkey retrofit solutions for exchanging conventional fuel injection systems on medium-speed marine engines in the output range from 1 MW to 15 MW to fully electronically controlled systems. With a minimum of engine modifications resulting in low investment and short conversion times the common rail retrofi t can be performed on nearly any engine type. The open construction allows the most flexible integration in the existing control and automation systems of a vessel. The system can be extended at any time by the addition of other HEINZMANN packages (e.g. dual-fuel retrofit for usage of alternative fuels) in order to stay up to date – whatever is needed by customer requirements or legal demands.

Examples of Common Rail Retrofit Installations demonstrate the benefits of this technology.

Common Rail Retrofit of Marine Engines

  • Vorteile

    Advantages

    • Constantly high injection pressure regardless of engine load always ensuring a good combustion quality with high efficiency and lowest soot emissions.
    • Precise and map based injection timing at the start and during injection provides lowest fuel consumption, reduced vibration and noise levels as well as extended component life.
    • Optional combination with permanent cylinder pressure monitoring allows greater balanced injection for all cylinders resulting in further improvements in consumption, noise and vibration.
  • High Pressure Pumps

    High Pressure Pumps

    The high-pressure pumps in the ODYSSEUS HDP-K series are characterised by maximum efficiency and robustness and optimally meet the requirements of harsh industrial environments, guaranteeing efficient and low-maintenance operation.

  • Injectors

    Injectors

    The new generation of ICR-DS injectors has a zero-leakage design that reduces the backflow of fuel by at least 75 % compared to conventional injectors.
  • EFI Controls

    EFI Controls

    The universal DARDANOS EFI controls combine their main function, speed control, with other performance features that are beneficial to the engine, including optimised fuel efficiency, higher engine output and reduced emissions.
  • High-pressure Accumulators

    High-pressure Accumulators

    The selection of high-pressure accumulator and line systems offered by HEINZMANN can be customised to meet special application and engine-specific requirements.
  • Pressure Limiting Valves

    Pressure Limiting Valves

    High Pressure Limiting Valves to protect common rail systems from overpressure. Fast switching for rapid pressure drop.
