CARRERA-ESCOBEDO, J.L. et al. Thermodynamic one-zone model with relations for combustion process for biogas fueled internal combustion engines. Rev. Mex. Ing. Quím [online]. 2013, vol.12, n.3, pp.649-660. ISSN 1665-2738.

The thermodynamic one-zone models allow trie calculation of the performance of internal combustion engine by means of a personal computer. These models use equations known as burning laws to calculate the combustion process evolution and have the characteristic of requiring low computing time. The exactness of the results obtained with these models depend on the user experience with burning law parameters, which result in a limitation of the applications for these models. Several thermodynamic one-zone models based on burned laws are known, however, the solution to the problem using equations relating geometric and operating parameters of the engine to the combustion process, in order to increase the accuracy without requiring the user to have experience with these laws, have not been studied. This paper presents an algorithm programmed in Visual Basic 2008 to calculate performance parameters of reciprocating internal combustion engines such as power, efficiency, spark advance, evolution of the combustion process and pollutant emissions. The simulation results are compared to experimental disclosures in the literature.
