A Design Study in Aluminum Castings - GM Cylinder Block                                          

Cylinder Block Description

As an example,  the cylinder block for the inline 5 cylinder engine is 24" x 17" x 13" (61 cm x 43 cm x 33 cm) in  block dimensions and has a cast weight of 86 pounds. 

  • The cylinder block casting incorporates many unique cast-in internal features which reduce machining costs, including: high pressure oil passages, oil drain-backs, the crankcase air passages, and coolant jackets and channels. 

  • On the exterior of the block there are numerous ribs, pads, channels, and holes for strengthening, weight reduction, and accessory attachment.
