This paper describes a study of the exhaust aerosols produced by a single cylinder Onan diesel engine using a rapid dilution sampling system. Diluted exhaust aerosols were analyzed with an electrical aerosol analyzer (EAA) and a transmission electron microscope.
Mass concentrations of particulate matter were determined by gravimetric filter analysis.
Volume mean diameters observed with the EAA were about 0.1 μm. Mass concentration measurements made with filters were in qualitative agreement with those calculated from the aerosol volume concentrations measured with the EAA.
