Abstract
A mathematical model for evaluating vehicle fuel consumption on a 100 km interval at standard operating conditions for the EUDC (Extra-Urban Driving Cycle) is presented. The extraurban cycle fuel consumption has two significant components: fuel consumption at average speed and during accelerations, and therefore, in the model, it is determined separately for two different operating modes: average speed and accelerations. In each of these modes fuel consumption is calculated based on the efficiency of the engine. Unlike previously developed models, which determine fuel consumption based on specific fuel consumption, ours determines fuel consumption based on the efficiency of the engine, which makes the model more adequate since it incorporates engine mode changes. The efficiency of the engine is expressed as a function of the speed mode of the engine and of the degree of power utilization of the engine.
