Icon Research Doctor DK-20 “Diesel Doctor” Engine Analyzer
The Icon Research Doctor DK-20 is a portable analyzer that measures the condition and performance of large diesel engines. Made by Icon Research a specialist in machinery condition monitoring and diesel engine performance monitoring since 1993 it is the next generation of the company Doctor DK series which has been a standard for marine diesel engine analysis for about 20 years. It is used by ship engineers, power plant operators, and engine service teams to check cylinder pressure and combustion and to spot problems before they cause breakdowns. It is launched along with version 6 of Icon Doctor engine analysis software.
Key Features
- Cylinder pressure measurement: the DK-20 is the single channel version for measuring cylinder pressure
- DK-20/FV two-channel version: measures cylinder pressure and fuel pressure at the same time using two simultaneous channels
- Smaller, lighter, and easier to use: Icon says it is more compact, rugged, and accurate than the earlier DK-2 with a touch screen and built in test as new features
- Accurate measurement: ICP sensor interface (2.4 mA at 24 Vdc nominal), a ±5 V input range, TNC connectors, and a typical amplitude accuracy of ±1%
- Bias voltage check: a 25 Vdc range for checking the ICP sensor bias
- Compatible with existing equipment: all pressure sensors, crank pick ups, and accessories purchased for earlier Doctor instruments work with the DK-20 so no changes to supporting hardware are needed
- Crank angle references: crankshaft and flywheel pick ups are recommended and permanently mounted on the engine
- Doctor Analysis software (version 6): processes measurements to produce engine performance and condition results with a Diagnostic Reporter module in the Doctor software to help evaluate the results
- Built for real marine users: designed with the requirements of ship engineers in mind
Typical Applications
- Cylinder pressure and combustion analysis on marine diesel engines
- Fuel injection pressure measurement (with the DK-20/FV)
- Engine performance monitoring and trending
- Condition based maintenance on ships and power plants
- Troubleshooting misfiring, timing, and cylinder balance problems
Why Choose It
The Icon Research Doctor DK-20 gives engineers a dependable way to take accurate cylinder pressure readings on large diesels. Compatibility with existing Icon sensors and software that interprets the results save time and protect earlier investments.
