Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The three dimensional flow field in the intake port of the non-road small spark-ignition engine was carried on the numerical simulation computation. Through the analysis of flow field, we studied how to reduce the mutations of intake port cross-section and improve the flow capacity of the intake port using numerical simulation method. After the parameter optimization, the gas flow increased to 31.24g/h from 27.84g/h under maximum valve lift, enhanced by 12.21%. Studies showed that there are two key points about optimization Design of small engine´s intake port, first, maintaining the flow of cross-sectional area of airway can prevent a sudden change on it and avoid the formation of dead air; second, handling the changes of structural in the corner.
