Study on Product Virtual Design for the Diesel Engine Combustion System

Abstract:

To carry out product virtual design for diesel engine combustion system, the top-down method is used. The diesel engine combustion system is designed and each part is modeled in Pro/E. Pro/E is a solid modeler and this offers considerable advantage for solid model creation. Normally, the geometry is first sketched in 2-D and then extruded in the third direction to generate a 3-D model. In Pro/E, it is important to first create the base geometry. The base geometry is that captures the design intent of the part to be modeled. This base geometry can be created using either the EXTRUDE or the REVOLVE options. Once this base geometry has been created, additional features like holes, rounds, chamfers, fillets, ribs, etc can be added in the finishing stages of the part creation. The center of the bowl does not coincide with the center of the cylinder due to the presence of valve pockets. The obvious advantage of this configuration is that is gives the true geometry of the piston and the connecting rod ports can be accommodated when the piston is at the top dead center.
