How is the cross section of liner O-ring grove is decided.

Always the cross section of groove must be greater than that of O-ring, the sealing is achieved by distortion of the ring by using various cross sections. The O- ring must never be volume bound in the
groove as it may cause the liner to get stuck while withdrawing and damaging the cylinder jacket.

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).
