Abstract
Cylinder head as one of the most important part in engine.It supports to the heat and vibration.It also with cylinder liner and piston consisting of the combustion chamber, which is the important componentsof Air System.Weather the cylinder head good or not will direct impact on the engine of power parameters and economical.
This thesis mainly studies the composition of the engine cylinder head assembly,including the function of every part,and designing the 3Y cylinder head on this basis.We start with working conditions and requirements of the cylinder head,then designed the intake valve,exhaust valve,intake channel,exhaust channel,combustion chamber,cylinder head bolt,etc,which from the design requirements, structural, the data size to finish it.Meanwhile,we use AutoCAD technology to draw the view of every direction,and then distribute them reasonablely.By the key parts,we also use the split view, local enlarged of the cartography,which will express the details more clearly.
