Click the Add button at the bottom-left corner of the screen. The system will clear all active fields and automatically generate the current Date of testing in DD-MM-YYYY format

​

Step 5: Executing Calculations and Submitting Data

 

1. Click the Refresh button at the bottom centre. The application runs its backend subroutines to instantly populate:

• Calculated Columns (Left Pane): Cross-section of the piston (cm²), Swept/Clearance/Cylinder Volumes (cm³), Compression ratio, Efficiencies, Indicated/Brake/Friction Horsepower (HP), and Brake Specific Fuel Consumption (g/kWh).

• Heat Balance Sheet (Right Pane): Calculates total Heat supplied, Heat to IHP, Heat to cooling water, Heat to exhaust gas, and Heat unaccounted in both Kcal and percentage allocations.

• Visual Assets: Generates the Work Done (kj) metric and updates a local bar chart plotting horsepower vs. current RPM.​

​

The system will clear all active fields and automatically generate the current Date of testing in DD-MM-YYYY format Engine testing Report

Module 2: Update Engine Record Screen

Use this form to search for, modify, and update existing test records stored in the database.

[Main Menu: Engine] ➔ Select Engine Number ➔ Modify Fields ➔ Click "Update"

1. Navigate to the top menu structure and select the EIS Update layout window.

2. Click the Engine number drop-down menu in the top left corner to fetch a list of all records saved in the database. Select the unique tracking code you need to adjust.

3. The application will instantly query the database and fill all field inputs, calculation grids, and heat balances with the selected historic record data.

4. Overwrite any outdated numerical data cells in the upper columns.

5. Click Refresh to force the calculations to update using your new values.

6. Click the Update button at the bottom-left corner to commit changes to the SQL Server backend.

(Optional) Click Print to display the individual localized sheet for this specific updated engine key

​​

Module 3: Reports Section (Comprehensive Data Output)

The Reports menu allows you to generate summary data sheets and printer-ready individual report printouts.

​

Type A: Individual Engine Testing Report

Selecting this printout provides a clean document layout optimized for single-vehicle diagnostics, tracking the entire geometrical configuration, pressure ratios, power metrics, and work outputs on one page. Use the navigation buttons at the top left to page through different records or select a specific Engine Number from the embedded quick-search dropdown field.​

​

Type B: Performance & Tabular Master Reports

 

By choosing specific tabular configurations under the Reports drop-down menu, you can open broader, date-filtered transaction spreadsheets. To isolate a specific testing timeframe, check the Date wise selection box, choose your From and To dates using the calendar drop-down menus, and click Load report.

 

• Horsepower Report: Focuses on power metrics, including Brake Specific Fuel Consumption (g/kWh), Indicated Horsepower, Brake Horsepower, and Friction Horsepower.​

• Efficiency Report: Report format is similar to Horsepower report. Isolates performance ratios, displaying Mechanical efficiency, Indicated thermal efficiency, and Brake thermal efficiency across multiple engine keys.

• Engine Capacity Report: Groups dimensions to analyse combustion room traits, pairing Engine displacement in cm³, Compression ratio, and Volumetric Efficiency.

• Engine Geometry Report: A detailed breakdown of mechanical physical design elements, mapping Bore Dia (mm), Stroke length (mm), Clearance Volume (cm³), Swept Volume (cm³), and Cylinder Volume (cm³).

​

Note: For all reports, use the administrative toolbar at the top of the screen to choose Page Setup, launch a full window Print Preview, export raw files, or output directly to a system printer by clicking Print.

​

Module 4: Heat balance sheet 

​​

​The Heat Balance Sheet module in the EIS (Engine Information System) provides a comprehensive overview of engine performance. After inputting all relevant engine and cooling system data, the heat balance is automatically generated and displayed within the application. This information is accessible for all engine numbers, ensuring users can easily track and analyze the heat balance for each engine in the heat balance sheet.

​

Module 5: Analytics Section (Performance Charts & Graphs)

This panel converts saved databases into interactive visual charts to help you evaluate engine operations across changing operating parameters.

[Main Menu: Analytics] ➔ Select Engine Number ➔ Select Chart Type ➔ Render Real-time Graph

1. Click the Analytics header from the primary top menu loop.

2. Select the targeting vehicle signature via the Engine Number drop-down filter field. The system will populate a summary panel with the engine's permanent design properties (such as Stroke count, Cylinder count, Bore size, and Stroke Length).

3. Select your preferred display style via the Chart type drop-down box (e.g., select Column for standard multi-variable grouping vertical bars).

4. The system automatically plots a multi-coloured bar graph tracking Horsepower & Efficiency variations across different engine run configurations (RPM levels):

 

• Blue Bars: Indicated HP

 

• Orange Bars: Brake HP

 

• Red Bars: Friction HP

 

• Low-profile Side Columns: Mechanical, Indicated Thermal, and Brake Thermal Efficiency levels mapped precisely against the engine speed variables (2998.7 to 3001.7 RPM).

 

Click Print Preview to check formatting or print to create a hard copy of the analytics dashboard graphic.
