Last Local version of the DIESEL-RK is 5.3.9.78 (June 2020).
Remote simulation with previous version (4.3) is available for academic and educational purposes. Differences between both versions are presented below.

If you want to use DIESEL-RK under non-administrator account the correct installation steps are:
1. Install DIESEL-RK under account with administrative privileges.
    Don't install software to default location (i.e. "C:\Program Files\Diesel-RK Net"),
    install to "C:\diesel-rk"  or   "D:\dieselrk", etc.
2. Set permissions for the installation folder to grant users  "Read/Write/Execute" access.
 

*   - With narration.
** - Slides only.

To get started create a new project and and follow "Wizard of New Project Creation".
1. The Wizard creates new data file with typical engine specification being nearest to your data.
2. Save data file and run simulation for testing.
3. Modify the data file corresponding with details of your engine design and operating parameters.
4. Run Simulations / Scanning / Optimization.
5. To plot graphs Drag-and-Drop functions from Tree View on the left panel to Diagram area.

What's new in version  5.3.9.78 in comparison with the version 4.1.3.143

In the late versions of DIESEL-RK the developers implemented special abilities for users to develop own User Models for different physical phenomena as Dynamic Link Libraries (DLL). Now DIESEL-RK has special interface to link User Models and set data for them. The examples of  FORTRAN sources for all kinds of User Model DLLs are presented in the distributive kit.

List of innovations of version 5.3.9.78 (2018) in comparison with  4.1.3.143 (2008)

1. Link with the User Model DLL intended for Friction Pressure simulation. This function is useful for users having rich experimental data about engine mechanical losses.
2. Link with the User Model DLL intended for Complex Emission calculation. This function is useful for users dealing with engine emission reduction problem, when it is necessary to decrease SFC, NOx and Soot simultaneously.
3. Link with the User Model DLL intended for Ignition delay prediction. This function may be useful for users dealing with PCCI and HCCI engine analysis, as well working with bio-fuels.
4. User can select Different models for Ignition delay prediction. It becomes possible to compare results obtained with different methods. It is actual for PCCI research.
5. Detail Chemistry simulation at Ignition delay prediction for diesel fuel and Bio-fuel is implemented. It is actual for research the PCCI with large EGR. Simulations with CHEMKIN code are used. Since 2010 there is used the extended mechanism of the Lawrence Livermore National Laboratory which considers 1540 reactions between 160 species.
6. Low Temperature Combustion phase is simulated. It is actual for research the PCCI with large Ignition delay.
7. Output the progress of mixture AutoIgnition preparation is done. It is actual for research the PCCI with large Ignition delay.
8. Improved Spray penetration model has been developed. New model is general for large Low and Medium speed diesels and for High speed light duty diesels with small nozzles diameter. The new model supports correct simulation of sprays propagation at high injection pressure (one was tested using Bosch data at Rail pressure of fuel being equal 2000 bar).
9. Simulation of Junkers engines with pooling rods is done. Progressive scheme of opposed piston opposed cylinders engine may be analyzed.
10. Variable Valve Actuation mechanism analysis and optimization is implemented.
11. Gas fuel of an engine  may be set as a arbitrary mixture of different gases. The properties of the gas mixture are calculated automatically depending on fractions of gases in the mixture. List of gases includes 13 items and may be expanded on request of customer. (Pipeline gas, oil gas, bio gas, syngas, etc are supported.)
12. Combustion model was improved to make it possible the correct combustion simulation at EGR up to 40% and Air/Fuel ratio (Lambda) down to 1.2.
13. The injection pressure (Sac pressure) is accounted at Ignition delay prediction.
14. Few approximations are possible to be used at heat transfer simulation: Original Woschni, Hohenberg, Eichelberg, Woschni's equation modified for HCCI and being general for different engines.
15. Combustion model is improved: Few independent fuel injection systems may be assembled in one cylinder; they may have own injection profiles and inject different fuels. See details.
16. Simulation of water injection is supported.
17. 1D simulation of flow in the engine ports.
18. Spatial sprays intersection is taken into account.
