How longitudinal expansion of liner is catered

Longitudinal expansion of liner takes place through the lower jacket.The sealing of cooling during expansion is accomplished by silicon rubber rings installed in grooves machined in the liner. Which slide over the cover as liner contracts and expands.

The o-rings are installed in a group of two, the space between two is open to atmosphere which will act as tell-tale holes of leakage.

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).
