MOTOR VEHICLE FUEL ECONOMY

The Motor Vehicle Testing Laboratory at the University of Sydney started vehicle testing last year. Fuel consumption and emission maps are generated in terms of the vehicle's speed and acceleation by on-line exhaust sampling and data processing. These maps provide information (a) to study the importance of design parameters on fuel economy, (b) to predict fuel consumption (and emissions) in real traffic situations and (c) to formulate a fuel consumption model in terms of vehicle design parameters and options. The maps obtained from a number of models indicate that vehicle maps are indeed a powerful and rapid diagnostic tool. The effects of changing vehicle mass, are shown and other experiments where emission control devices were deliberately disconnected or were faulty, have been performed. Fuel consumption and emissions have been predicted for Sydney traffic and the effects of changing the speed limit have been estimated. The maps are providing data for the fuel consumption model which is under development. (Author/TRRL)
