| Abstract: | A thermodynamic and a 2-D numerical computational model are proposed for calculating the discharge coefficient of connecting passage of swirl chamber diesel engine. The transient change of discharge coefficient via engine crank angle is calculated for the first time. The effect of some parameters (connecting passage area, angle, position and piston top clearance, pressure ratio, flow direction) on discharge coefficient are studied and analysed. |
