Simulation of diesel cycle and thermal state of combustion chamber components

The article describes a technique to define more exactly the thermodynanic calculation of the diesel engine cycle. Increasing the accuracy of the calculation is due to the use of local surface temperatures of combustion chamber surfaces. The calculation of the thermal state of the pistoncylinderunit is performed by the finite element method in stationary axisymmetric formulation. An example of combined calculation of the diesel cycle and the combustion chamber thermal state is given, a comparison with experimental data is presented.
