An undiluted exhaust hydrocarbon (HC) speciation method, using flame ionization detector gas chromatographs, is developed to investigate HC species from conventional and low-temperature premixed charge compression ignition (PCI) combustion pre- and postdiesel oxidation catalyst (DOC) exhaust. This paper expands on previously reported work by describing in detail the method and effectiveness of undiluted diesel exhaust speciation and providing a more detailed analysis of individual HC species for conventional and PCI diesel combustion processes. The details provided regarding the effectiveness of the undiluted diesel exhaust speciation method include the use of a fuel response factor for HC species quantification and demonstration of its linearity, detection limit, accuracy, and precision. The listing of individual HC species provides not only the information needed to design surrogate exhaust mixtures used in reactor tests and modeling studies but also sheds light on PCI combustion and DOC characteristics. Significantly increased engine-out concentrations of acetylene, benzene, and toluene support the theory that net soot reduction associated with PCI combustion occurs due to the reduction of soot formation (as opposed to increased soot oxidation). DOC oxidation behavior differs depending on the combustion characteristics, which change exhaust species and temperature.

A study has been made of diesel exhausts, and this paper relates the essential parts of what was found. Exhaust pollutants and their physiological effects are examined, and the steps taken by the National Coal Board for the protection of personnel and against dangers from explosions and fire are considered. The action taken to comply with statutory exhaust gas checks is given, and the necessary minimum ventilation of tunnels to acceptable standards is detailed. Other aspects of exhaust fume control, including that in confined spaces above ground, are dealt with. Finally, methods of treating diesel exhaust emission are suggested.
