The main goal of the project was the development a computer code capable to simulate the operation of a multi-cylinder common rail diesel engine. The code should be used in investigating the possibilities of a commercial engine to be adapted for military applications by increasing the engine output while reducing fuel consumption and assure safe operation of the engine. In the process of developing the simulation model and the corresponding computer code, the critical loading of the engine bearings and the piston assembly were determined by developing detailed models for loading and stresses in the bearings and the piston. Experimental setups were developed to validate the models. To correctly estimate the fuel consumption, a detailed friction simulation model has been developed. Both experimental and analytical investigations were conducted to allow better estimation of the ignition delay, combustion and emissions. The Computer based Adaptation Tool has been built in a modular form in the Matlab-SIMULINK platform. The advantage of this configuration resides in the fact that modules could be replaced as new modules are developed, for example the ignition delay and the combustion modules for different fuels that could be used by the diesel engine. Finally the Computer Based Adaptation Tool has been validated by experiments conducted on a 2.5 liters common rail diesel engine both for steady state operation and for engine transients.
