A typical diesel engine was used for measurements of particulate emissions. It was felt that diesel engine, popular because of its low emissions of hydrocabons and carbon monoxide, has not been developed to its full potential. Hot sampling techniques for the measurement of particulate matter were developed that gave representative and repeatable results. An inertial impactor was used to collect and size the particles. Four engine operating conditions were studied to assess the effect of exhaust temperature and engine speed on the nature of the particles. Both scanning and transmission electron microscopes were used to analyze the particles collected. A number of micrographs were taken which were used to determine the physical size of the particles as well as to illustrate this distribution and geometry. The results indicate that basic particles do not change greatly with different engine operating conditions.
