Abstract
This work aims to describe the method and results obtained of a reciprocating combustion engines simulation script developed in python language. The program uses graphic interface and has a didact purpose of illustrate the thermodynamic and combustion processes which occurs in a reciprocating engine allowing better understanding of its operation and design. Three cycles are available to assessment: Otto, Diesel and Dual. Type of fuel and air-to-fuel ratio can also be selected. Starting from the type of the operating cycle and the geometric, combustion parameters and the cranckshaft rotation the program can simulate the engine performance and predicts the exhaust gases emissions if the combustion is considered complete. The output performance parameter are the state thermodynamic parameters, the indicated and brake power, torque, efficiencies, specific fuel consumption and exhaust gases emissions. Several simulations were carried out in order to compare the results with the actual engines data. The simulations presented results with values near to the of-the-shelf data found in research validating the program method for internal combustion reciprocating engines analysis.
