    Doctor Analysis Software
    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 hundreds of diesel engine operators. A program of on-going developing has ensured that the software continues to lead the field in shipping, power generation and many other applications. The software is supplied on a single CD together with a hardcopy Step-by-Step Guide to enable the operator to familiarize themselves with the application as quickly as possible. The intuitive nature of the application and Windows “look and feel” makes the learning process even easier. The software is supplies with a suite of sample engine measurements to experiment with. There is no restriction on the number of computers that the software can be used on, so engine measurements can be freely passed between operators, analysts and managers.

    First of all, the configuration of the engine being measured is entered in the Engine Configuration Screen. Settings such as engine geometry and firing order are entered here. An unlimited number of configurations can be stored for later use. The configuration storage is flexible and allows multiple ships or plants each to have multiple engines in separate databases. There is no limit to the size or the number of individual databases. The software supports both portable and “On-Line” versions of the Doctor system. Measurements are downloaded via the computer’s serial port and stored in the Doctor database. Sections of the database can be compressed into .idk archive files and emailed to colleagues anywhere in the world for further analysis or comparative work.

    The basic traces that can be observed are Pressure-Angle, Pressure-Volume and Derivative (Rate of Pressure Rise). From these traces, various parameters are derived such as power, MIP, rate of pressure rise, and many others. In addition, user-defined variables can be entered, such as exhaust gas temperature. These values can be shown in tabular form for easy comparison. Variations are automatically calculated, such as various in power between cylinders. Cursor readouts are available on single or multiple traces. When more than one trace is displayed, the cursor will show the data on all curves at that position together with the maximum deviation from lowest to highest.

    Hardcopy printouts are available at the touch of a button. These can be in black and white or color.

    Operation of the software is primarily Windows “point-and-click” style. However, the Doctor software has many unique features that make it so easy to use. For example, traces can be overlaid or removed using the Trace Selector Box. Ticks indicate which traces are selected enabling comparison of cylinders, test runs and even different engines. Reference traces are also available.

    A powerful click-and-drag zoom feature is incorporated. To enable the same zoom to be called up for viewing and reporting purposes, three “favorite zooms” can be defined, and these are recalled at the click of a button.

    Data Archiving and Recall
    Data can be archived for historical purposes or for transferring engine measurements between interest parties. Measurements selected by engine and by date can be compressed into a single file for transmission (via email for example) and restoring.
