Development of an electronic instruments to measure the fuel consumption of tractors

Abstract: The fuel consumption is one of the most important measurements of any research and tractor test as it represents the power required for any operation. At the Testing and Research Station for Tractors and Agricultural Machinery, Alex., there are two instrument setups to measure the fuel consumption during the tractor test. One is a locally constructed (customary setup) and the other is imported. The local instrument has a special fuel tank, with a volume of 5000 cm3, which is hanged beside the tested tractor. This tank is filled manually by a labor, many times during the test. Also, it has a bulb marked by two signs one on the top, and the other on the bottom, start of the test provide a certain amount of flow which represents the volume of the bulb at specific time measured manually by stop watch. From the volume of the bulb and the average measured time, the fuel consumption can be obtained. At the high speeds, it is not easy to record time accurately, as the observer should run beside the tractor at its speed. This instrument is used until now at different bulb sizes depended on the tractors sizes. The other instrument was imported from U.S.A. It is a photo optic instrument and consists of four pistons flow meter, flow meter transmitter, vapor and level controller and flow rate indicator. The movement of these pistons is converted to a circular motion at the central crankshaft that is coupled to a magnet in flow meter. This motion is sensed by an external electronic transmitter that coverts flow into a voltage, pulse train for further processing. The flow rate indicator read the output on a rear panel. This panel could be connected to a frequency card in the PAC. A simple and inexpensive electronic instrument was designed to measure the tractor fuel consumption under laboratory and field conditions. This instrument is connected to the regular tractor fuel system during the measurements. The function of this instrument is to measure the time needed to consume a constant volume of fuel automatically. The designed instrument was tested in the laboratory as a function of change in the tractor load. While it was tested under field conditions as a function of change in the tractor forward speed. The laboratory tests indicated that the instrument was good enough to measure the fuel consumption with insignificant errors. The designed instrument can be also used satisfactory under field conditions that offering a way to accurately quantify energy requirements for any agricultural operation. This instrument is easy to use, locally manufactured, accurate, small in size and simply to maintain.
