IMPROVING THE MEASUREMENT OF CHASSIS DYNAMOMETER FUEL ECONOMY
The overall chassis dynamometer-carbon balance fuel economy test yields undesirable variation of results and needs refinement. Major factors influencing the accuracy and repeatability of test results are: CO2 measurement accuracy; variations in following the driving cycle; vehicle-dynamometer interface conditions; and associated calibration, calculation, test technique and procedural methods and controls employed. Each of these factors is discussed in terms of its relative importance and causal factors, along with suggested or potential means for improvement.
