FORMULAE FOR PREDICTING FUEL CONSUMPTION OF CARS

摘要: An instantaneous fuel consumption model is derived based on the average travel speed (including delays), running (excluding any stopped time), delay time/and distance, positive kinetic energy changes and total section distance. The method used involves determination of idle parameters by direct measurement, rolling resistance from constant speed-cruise acceleration coefficients data. more sensitive to conditions than those regression analysis. can be predict when speed-time traces individual vehicles are known. It also as a basis in derivation functions describing elemental well aggregate with minimum reliance analyses. (TRRL)
