Diesel Engine Emission

An experimental study is made on the emission of a single-cylinder direct injection diesel engine with different proportions of GDE and diesel. The study shows the mechanism when GDE is added to diesel to reduce diesel emission. And an analysis of pollutant emission is made on the regularities of variation with engine load changes. The results show that the addition of diesel oil in the volume fraction of 10% to 20% of GDE can significantly increase the thermal efficiency, shorten the duration of diesel combustion, substantially decrease carbon smoke and CO in emission under the high-load conditions and slightly lessen the NOx emission, but HC emission still remain basically unchanged.

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.
