Common Rail Fuel Injection Retrofit for Marine Engines

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 Key Features

Constantly high injection pressure regardless of engine load always ensuring a good combustion quality with high effi ciency 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.
