The Influence of Fuel Properties and Test Cycle Procedures on the Exhaust Particulate Emissions From Light-Dity Diesel Vehicles
Published April 06, 1993 by Institution of Mechanical Engineers in United Kingdom
The effective specification of diesel fuels requires a sound basis of understanding of any relationships between the fuel properties and vehicle performance. This paper describes the approach used by Shell Research to gain this understanding through a comprehensive test programme on emissions from light-dity vehicles. Fourteen vehicles, three transient test cycles and over sixty fuels formed the basis of this study. Broad interpretation and statistical analysis, applied to the complete data set, has provided models for particulate emissions in terms of fuel and engine characteristics. Measurements on a wide range of fuels and a number of vehicles are required to allow general conclusions on fuel quality effects to be drawn.
