| Review: |
This is a collection of 16 papers from the General Emissions and Emission Measurement and Testing Methods sessions of the 1999 SAE International Congress and Exposition. The papers include: Simultaneous measurement of soot mass concentration and primary particle size in a diesel engine exhaust; Numerical analysis of mass emission measurement systems for low-emission vehicles; The control of TP pressure in emission sampling systems; Proportional ambient sampling; Speed and power regressions for quality control of heavy duty vehicle chassis dynamometer research; CO2 emission and fuel consumption; Statistical methods for solving the diesel engine fuel consumption/emission conflict; Reduction of N2O from automobiles with 3-way catalysts; Mathematical modelling of a balanced purge solenoid valve; and a new method for emission analyser calibrations. |
