Maintenance Activities

In order to better protect the engine, air filters with high efficiency should be used as well as appropriate maintenance activities. Maintenance activity must take into account the behaviour of the air filters during exploitation, namely the increases of the gaso-dynamic resistances they produce while air filters are used. This paper presents the variation of the pressure restriction depending on the amount of dust retained by the air filters and also the storage capacity of dust by the air filters. Filters are loaded on a laboratory rig with dust from the roads of Bucharest.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
