ENGINE BLOCKSThe engine block houses all of the major components that make up the bottom end of a motor. The block, which is also known as the cylinder block, is where the crankshaft spins, and the pistons move up and down in the cylinder bores, fired by the fuel combusting. On some engine designs, it also holds a camshaft.
Usually made from an aluminum alloy on modern cars, on older vehicles and trucks it was commonly cast iron. Its metal construction gives it strength and the ability to transmit heat from the combustion processes to the integral cooling system in an efficient manner. |
