Journal of Polish CIMAC

2007

Vol. 2, no 2

99-105

In the paper causes of a container ship auxiliary engine turbocharger self damage during its service at sea have been analyzed. The damaged turbocharger working elements have been presented. The direct reason of the turbocharger damage was its explosion. The damage cause analysis takes into consideration the possibility of stimuliaccumulation leading to the damage as well as damage causes overlapping and the influence of quality of fuel feeding the auxiliary engine. Eventually the turbocharger damage has been attributed to fuel quality. Probability of fuel seeping into exhaust manifold and scavenge air receiver due to injector needle suspension as well as ignition and combustible properties of fuel feeding the auxiliary engine have been focused on. Injector testing results achieved on trial stand and fuel quality analysis carried out by means of FIA-100/3 analyzer have been presented.
