Nox Emissions from Diesel Engines, Control and Measurement Techniques.
Air:II Control of Nox and Sox Emissions Aiche Symp Ser 1975 71(148):114-119
Several different types of diesel engines have been studied in an experimental investigation to determine how emissions and energy performance are affected by engine modifications and adjustments made to reduce nox emissions. The engine variables and modifications that were studied include fuel injection timing, exhaust gas recirculation, and after-cooling. Water induction and emulsified fuels were also tried in the experiments. The best results in terms of emissions reductions with least penalty to engine performance were obtained with water induction.
