Subsection 6.4.1 The Cylinder Block

The cylinder block, as shown in Figure 6.4.4, is the main structure of an internal combustion engine. It houses the cylinders where the engine’s pistons move up and down, and it provides the structure and rigid frame for the engine’s cylinders, water coolant and oil passages, and support for the crankshaft and camshaft bearings. It is generally a single unit made from cast iron.
