Abstract

The paper is focused on the issue of measuring the amount of fuel in the tank of truck, construction and agriculture machine. The gradual expansion of of the share of the biocomponent in diesel fuel results in greater measurement errors via the capacitive probe in the fuel tank. The proposed solution, which uses three electrodes leads to increased accuracy in measuring of the amount of fuel in the tank. According to standard EN 590, the measurement error of the new capacitive probe is only 1.5% when using diesel. The highest measurement error 4% is achieved when using neat rapeseed oil methyl ester. The previous solution of the capacitive probe when using diesel fuel according to EN 590 achieved a measurement error of 2.5%, but it increased significantly with the proportion of rapeseed oil methyl ester up to 70% when using neat rapeseed oil methyl ester. The new capacitive probe concept with two positive electrodes and higher accuracy can be used to evaluate driving style towards economical and environmentally friendly driving. It is also possible to focus on safe driving style of drivers using other operating parameters. The aim of the paper is to compare the capacitive probe with one and two positive electrodes and demonstrate their use in evaluating the driving style of drivers.
