Experimental & Numerical Investigations of the effects of the Intake Port Geometry on the In-Cylinder Flow of Direct Injection Spark Ignition Engine, Ph.D. Dissertation Sharif University of Technology ; Shafii, Behshad (Supervisor) ; Kazemzadeh Hannani, Siamak (Supervisor)
Abstract
The design of inlet ports for spark ignition internal combustion engines has a direct and well-known influence on performance and emissions as a result of changes in volumetric efficiency and fuel burn rate.The design of ports is becoming more critical as SI engines are developed further to meet increasingly stringent exhaust emissions legislations. Lately further emphasis has been placed on port design by the re-emergence of the direct injection gasoline engine.
Due to lean burning, combustion instability and increasing the cycle to cycle variations, in the direct injection engine, combustion charactersitics will be improved by increasing the tumble in-cylinder flow and the turbulence...
