Electron paramagnetic resonance (EPR) spectrometry has been used to study diesel particulate matter. The EPR signals for a graphitized carbon black and particles collected from two different diesel engines have been compared. Variations in the line w

Isosteric heats of adsorption were determined for 18 compounds with low injection volumes. The isosteric heats of adsorption of benzene and hexane on the pretreated Diesel samples were compared with those of the same compounds on a graphitized carbon

This study involves the chemical characterization and biological assay of diesel particulate matter generated from a single-cylinder, direct-injected diesel engine. This engine was powered with a pure hydrocarbon fuel. The total extract obtained with

Diesel engines are a source of suspended ambient particulate matter, and some concerns have been raised about the health effects from the inhalation of these particles. Nitrated polycyclic aromatics adsorbed on these particles have been shown to have

Two synthetic Diesel fuels, one derived from oil shale and the other from tar sands, were compared to a petroleum-based number-two Diesel fuel. These fuels were tested in a single-cylinder, air-cooled, direct-injected, light-duty Diesel engine. Compa

An instrument has been developed (termed the methane analytical system) enabling diesel methane emissions to be quatified separately from total unburned hydrocarbon emissions. The instrument employed gas-chromatographic principles whereby a molecular
