||This paper presents the application of modern methods to reproduce
a model of selected features of the complex geometric components of present
medium-speed marine diesel engines. Geometrical data was obtained in
experimental investigations of new objects operating in natural conditions,
where measurements of some structural features are very difficult and burdened
with great uncertainty. To obtain data for modelling, the analyses of
two-dimensional images were used. The aim was to study the geometrical
features of the main elements of fuel injection equipment to develop
relationships between diagnostic signals to determine the technical state. Such
examinations are also useful for the evaluation of the wear and damages of
elements when operating in extremely difficult conditions.
As a result of geometric measurements, it was possible to get a set of points
and to produce digital images of objects.
