A Method for Calculating the Fuel Consumption and Emission of Vehicles Based on Driving Speed

Abstract
The Institute for Internal Combustion Engines and Thermodynamics
of the Technical University, Graz, has developed a method whereby a
digitalized speed curve may be evaluated in terms of fuel
consumption and emission of HC, CO and NO\dx using a computer
program. The entire curve is divided into time elements which are
characterized by speed and acceleration. Road gradients can be
considered using the equivalent accelerations. The consumption and
emission values needed for calculation were determined by
measurements made on a certain number of vehicles on the test
stand.
The method was developed primarily for judging road networks. It
may also be used to compare various test cycles mathematically.
