On-Line Cylinder Pressure Analysis

Description

The DK-200 Engine Surveillance system is the latest innovation from Icon Research.  It is a powerful combustion system that allows you to continuously monitor your engines and have any issues alerted as theyhappen.

The system has been developed with complete engine surveillance and flexibility in mind. As such 24 input channels are available which allows the addition of inputs from other instrumentation to read parameters such as exhaust temperature, vibration inputs and fuel flow/temperature simultaneously with cylinder or fuel pressure readings.

Installation is simple with all hardware contained in a single rugged box measuring 40cm x 50cm. A full colour touch screen makes setup easy and provides “easy to view” status screens in the engine room. All input data is gathered at the front-end, is processed and fed to an Ethernet link going to a hub which can network multiple systems. The hub is connected to a PC in the control room which runs the software application to display and diagnose engine reading from one or more DK-200’s in real-time.

An overall summary screen displays the status of all engines being monitored with a traffic light system using pre-determined programmable thresholds. If an issue is identified the user can “drill-down” to examine a specific engine or cylinder exhibiting a problem.

On-line systems can be set to record readings automatically at pre-set intervals, can be set to give a reminder to record a test set, or a snapshot can be taken at any time by the click of a button. Meanwhile the system monitors the engine(s) 24/7 and a visual display is available at all times.

Readings can be transferred into the same software package as used by the portable Doctor.

Friendly Presentation

Presentation and analysis of results is done through Windows based software which is simple to learn and operate. The clear graphs, charts and tables can be printed at the click of a button. Zoom, Cursors and Overlays add to powerful analysis. Overlay any number of cylinders or any number of tests on a cylinder for immediate visual comparison.

The Main screen shows the overall status of all engines that are being monitored. From there, there are a variety of screens that show the condition of all the cylinders for he selected engine.

The History screen shows trend values for various parameters for multiple cylinders, allowing quick comparison of values. Similar information is available in the Histogram screen where bar graphs present the data in an easily understood format.

The Analysis screen shows live traces for the cylinders and it is possible to use many of the features that are available in the Portable system software, including data set selection, zooming, cursors, alternative trace types (pressure / angle, P V diagrams and rate of change of pressure plots).

Traces can be viewed live and will show exactly what your engine is doing in real time. Scalar data may be stored (such as the trend values) may be stored at a more frequent rate than trace data if required to save on memory in the PC.

Sensors and Pickups

To ensure the highest accuracy, especially for calculated power, only the highest quality sensors and pickups are used. The high accuracy pressure sensors have high temperature resistance and a long and stable operating life.

The on-line systems use a small, permanently connected pressure sensor that fits into an adapter that is fitted under the indicator cocks.

Pickup Configurations

Twin inductive crank pickups eliminate the effects of speed variation for the highest accuracy on main engines.Single inductive crank pickups give an economical oil and dirt immune system for generators and auxiliary engines.

Support

Prompt Response:
Icon provides excellent support for Doctor systems. Should any operational problems be encountered, telephone support is available during office hours; however Email is more commonly used. Questions are normally answered within 24 hours. If the support extends into interpretation of results, a bureau analysis service is available.
