<p>The present invention relates to a method and a device for determining the specific fuel consumption of an internal combustion engine by measuring the change in weight of a pot containing fuel for consumption by the engine during a specific, selectable time. The device for execution of this method includes a data acquisition system (9) equipped with a number of measuring points. Sensors at the measuring points feed, through the data acquisition system, signals representing the change in weight of the fuel pot (1), the speed of the engine (2) and the torque of the engine into a computer (6). The computer is programmed for measuring at constant speed and constant torque, within selectable tolerance, and for measurement during a specific, selectable period of time. The method according to the invention permits the use of statistical methods to guarantee reliable and accurate measurement results with the shortest possible measurement period, while providing high flexibility in interfacing with the environment (operator, central computer system).</p> |
