Abstract Turbocharging has been demonstrated as a key technology to enhance fuel efficiency in the automotive field that faces increasingly stringent emission regulations. Due reciprocating engine, pulsating flow feds turbocharger turbine, which experiences conditions far from continuous scenario. In this work, effects of characteristics mass pulse, parameterized through amplitude, frequency, a...

Positioning the catalysts in front of turbocharger has gained interest over recent years due to earlier onset temperature and positive effect elevated pressure. However, several challenges must be overcome, like presence higher pollutant concentrations absence or insufficient diesel oxidation catalyst volume at this location. In context, our study reports a systematic investigation on pressure ...

Changing the compression ratio and presence of turbocharger are two important issues, affecting on performance, and exhaust emissions in internal combustion engines. To study the functional properties and exhaust emissions in regards to compression ratio at different speeds, the numerical solution of the governing equations on the fluid flow inside the combustion chamber and the numerical solut...
