Tie rods, stresses acting on tie rods, how tie rods are attached in modern man b&w engines.

In order to minimize stresses due to bending in bed-plate without using extra material tie rods are used to transmit the combustion forces.They are pre-stressed in assembly so that engine is always in compression. Two tie rods are fitted to each transverse member and they pass in tubes through the
entire structure of the engine from bed plate to cylinder cooling jacket. in order to minimize bending tie-rods are kept close to the center line and bearing keeps are kept in place by jack bolts. They are restrained from motion using pinch-bolts.

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).
