Trindade, W. and Santos, R., "Combustion Modeling Applied to Engines Using a 1D Simulation Code," SAE Technical Paper 2016-36-0347, 2016, doi:10.4271/2016-36-0347.
Modeling of internal combustion engines is a multidisciplinary activity that is continuously growing and is more and more present during the development phase of an engine, mostly today when the time to production is reduced. There are different levels of complexity when thinking about engine modeling, from the high level of details of the 3D models to a much simpler approach of the 1D models. The last is the most adequate to analyze the whole engine system with multiple components together, looking for its performance. It is also interesting and important to observe the advances of the combustion modeling and prediction of emissions that these models allow. In this article the possibilities of 1D modeling is presented. A quick overview on available simulation codes is done and some models of combustion are studied. Finally, 1D engine models are built to verify their advantages, drawbacks and results in terms of engine performance.
