Description of the salient parts
Modern engines designed for increasing power to weight ratios are reliant on not only stronger materials but also on careful design. Each component design must not only be optimised for its own purpose, but also in some cases, to provide strength to the overall structure. An example of this is how the bedplate and A-frame combine to create a strong rigid box able to resist the forces of combustion and maintain essential alignment for the crankshaft and over moving parts.The entablature not only supports the cylinder liner and head it also creates areas for cooling water and scavenging air.
Fabrication techniques are extensively used simplifying castings and speeding assembly times by reducing the number of fastening.In order to obtain ideal strength transfer between components the fastenings must have intermit contact with the surfaces of the components and hence fitted bolts are used.
Cylinder blocks must be cast, due to the difficulties in casting large components generally single cylinder blocks are created joined to each other and to a common fabricated A-frame/bedplate box.
