Abstract
As environmental pollution reduction devices were installed in diesel engines, a gas flow analysis of intake and exhaust systems is required. A gas flow analysis in 3D format needs a high-resolution workstation and enormous time for analysis. Therefore, the method of characteristics was used for a gas flow analysis with a fast calculation time and a low-resolution workstation. An experiment was conducted on single cylinder diesel engine to measure cylinder pressure and exhaust pipe pressure. In order to validate a gas flow analysis using the method of characteristics, the results analyzed under the same conditions as the experiment were compared. As the results of the analysis using the method of characteristics, the cylinder pressure showed accuracy; however, the exhaust pipe pressure was inaccurate. In the future, the shortcomings of the analysis using the method of characteristics will be supplemented by using the 1D-3D coupling method.
