Journal of the Brazilian Society of Mechanical Sciences and Engineering, v. 27, n. 3, p. 266-273, July/September, 2005.1678-5878https://repositorio.fei.edu.br/handle/FEI/4374A new phenomenological model is introduced by applying established conceptual models for direct injection combustion to develop a mathematical description of events. The model has the capability to predict particulate mass output, as well as a particulate mass history over a single combustion event. The model was developed in a Matlab-Simulink environment to promote modularity. Results of particulate mass output from single cylinder laboratory engine, and six-cylinder vehicular engine were used to determine the validity of the predictions made. Although predicted values do not perfectly match measured values, there is certainly reasonable agreement.
