Gas sampling and analysis techniques developed for studying preflame reactions were applied to determine combustion chamber formation of inorganic and organic materials found in spark-ignition engine exhaust.
Results show that oxides of nitrogen are flame-formed, decay somewhat in the post flame gases, and then are “frozen” from further decomposition. The exhaust nitrogen oxide concentration is a weighted average of the spatial- and time-dependent combustion chamber concentrations.
Organic exhaust constituents contributed by combustion-chamber slow-combustion reactions were chromatographically found to include olefins, aldehydes, ketones, and ring ethers when operating with isooctane fuel. Addition of TEL to the fuel inhibits slow-combustion reactivity reducing concentrations of slow-combustion products in the exhaust.
