“…Also, many publications that examine the reliability and the ability of the software are available in the literature. Combustion analysis has been performed by working together with some of the studies conducted to determine the usability of the SRM software on different engine concepts and combustion conditions such as fuel from manifold injection HCCI engine modeling, − modeling of the effects of engine combustion with an alternative fuel mixture, − early and one injection HCCI engine modeling, double jet HCCI engine modeling, multicycle nonpermanent simulation and control, − soot formation, and a CFD program that is a KIVA program …”

In recent years, much research has been performed in order to decrease fuel consumption, noise, and exhaust emission levels in internal combustion engines. In this study, the effects of excess air coefficient on performance and exhaust emissions (CO, CO2) of an HCCI engine fueled with primary reference fuel (PRF) were investigated for different intake air pressure and temperature values. The simulation studies were performed by using SRM Suite software. The chemical kinetic mechanism, which contains 138 species and 633 reactions that are embedded into the program, was used to simulate the combustion of the PRF fuel during the combustion simulations. The analysis covers the full cycle and provides data about induction, compression, combustion, expansion, and exhaust. The exhaust emissions, cylinder pressure, and heat release rate results were compared with the experimental data. The zero-dimensional software (SRM Suite) gives quite reasonable results compared with the experimental data, and it has advantages such as the shorter solution time and the unlimited chemical kinetic mechanism compared with the three-dimensional combustion simulation software.

“…Other models presented elsewhere for ethanol combustion include from 43 to 135 chemical species [16,17]. From a 47-species model applied to an ethanol fueled engine, methane (CH 4 ) emission was found at higher concentration than ethane (C 2 H 6 ), both participating on aldehyde formation [18]. Acetaldehyde and formaldehyde were found in significant quantity, the former higher showing higher concentration.…”

This work presents a numerical simulation model for aldehyde formation and exhaust emissions from ethanol-fueled spark ignition engines. The aldehyde simulation model was developed using FORTRAN software, with the input data obtained from the dedicated engine cycle simulation software AVL BOOST. The model calculates formaldehyde and acetaldehyde concentrations from post-flame partial oxidation of methane, ethane and unburned ethanol. The calculated values were compared with experimental data obtained from a mid-size sedan powered by a 1.4-l spark ignition engine, tested on a chassis dynamometer. Exhaust aldehyde concentrations were determined using a Fourier Transform Infrared (FTIR) Spectroscopy analyzer. In general, the results demonstrate that the concentrations of aldehydes and the source elements increased with engine speed and exhaust gas temperature. The measured acetaldehyde concentrations showed values from 3 to 6 times higher than formaldehyde in the range studied. The model could predict reasonably well the qualitative experimental trends, with the quantitative results showing a maximum discrepancy of 39% for acetaldehyde concentration and 21 ppm for exhaust formaldehyde.
