Diesel Engine Analysis Software
Icon Research released a brand new version 6 software in 2014. Since its first release in 1994, the Doctor Analysis Software’s comprehensive analysis features combined with ease-of-use has made it first choice for thousands of diesel engine operators. A programme of ongoing development has ensured that...
Portable systems provide the simplest method of monitoring, requiring the minimum amount of installation wiring.
On-line systems provide the comfort of continuous real-time engine monitoring.
All systems interface to the same highly regarded PC analysis software allowing a mixture of systems to be used throughout a fleet.
Why Should Engines Be Analysed?
To help achieve efficient and reliable diesel engine operation, analysis of "draw cards" and "indicator cards" is well recognised. From these graphs, engine timing, compression variations, cylinder output and many other characteristics can be analysed. Small variations in timing for example can have a large effect on other parameters. Timing that is one degree late will increase exhaust temperature by up to 10ºC and increase fuel consumption by up to 2%.
Properly balanced cylinder output leads to smoother and more efficient engine operation. Knowing how your engine is performing not only leads to more efficient operation, but can highlight developing faults and assist with targeting engine maintenance. With typically 60% of a ship's costs going on bunkers, any fuel saving is worthwhile, however small. At around 10% of the ship's budget, optimisation of maintenance can provide large savings as well. Avoidance of down time due to recognising developing engine problems early keeps ships sailing.
The Doctor systems are optimised to produce engine results simply, reliably, and accurately. The portable and the on-line systems are both designed with expert marine engineering input. The results allow balancing of power in the cylinders, optimisation of injection timing and help to pinpoint engine faults. Many developing faults can be detected early enough to avoid major engine damage, saving maintenance costs and possible downtime.
Doctor PC software is a fully featured Windows application, optimised for Windows XP, Windows 7 and Windows 8 operating systems. The results are stored in a library file, which can contain all the data for a vessel or, in the head office, the data for a whole fleet. This simple data management concept sets the Doctor apart from other systems. Full screen graphs, tables and bar graphs put as much information on the screen as possible. Each test can be looked at with all cylinder graphs overlaid to make comparison easy.
Full tests on an engine can be overlaid to compare historical results. The overlay concept has been extended so that it is possible to compare multiple engines simultaneously. For fleet management purposes, results from several ships can be overlaid. Results from ships can be sent by email on a regular basis. This is done by simple importing and exporting of logbook files.
In a new initiative the latest Doctor software adds Propeller Curve and Shop/Sea Trial analysis further strengthening its capabilities.
