Research output: Contribution to journalConference articlepeer-review


Flying Hot-wire anemometer measurements have revealed the effect of the inlet port angle, and valve lift on the spatial structure of turbulence in a model internal combustion engine. The present experiments are carried out at the BDC, intake stroke at a low piston speed in a dynamically similar flow. The data are presented using both cycle resolved and ensemble averaging techniques. The experiments are carried out at three different measurement positions across the engine cylinder. The inhomogeneity of the intake turbulence is found to be considerable. The role of the inlet jet flow is shown to be crucial.
