Abstract

Fuel consumption is one of the important indicators characterizing the technological and technical condition of the vehicle and its operational properties. During operation, the reliability of the machines decreases and fuel consumption increases, as does the amount of harmful substances emitted into the atmosphere. Therefore control of a fuel consumption allows to estimate real quality of the vehicle, and also optimality of conditions of its operation. Today, there are many methods and devices for monitoring liquid fuel consumption in vehicles. The overwhelming majority of them are distinguished by their high cost or unsatisfactory accuracy and reliability of the operation, as well as the complexity and problematicity of installation on a vehicle, inconvenience in their intended use and the like. That is why, even on the most modern vehicles, there are still simple, reliable, but not accurate enough and such that do not meet the requirements of the time, means for monitoring liquid fuel consumption. Meanwhile, the problem of economical fuel consumption, which is also related to the problem of environmental protection, requires an urgent solution that cannot be achieved without the use of simple, reliable, safe and inexpensive means of controlling the consumption of liquid fuel on each vehicle. In theoretical terms, this problem is the subject of multivariate analysis with many random factors (type and condition of the vehicle, type and condition of the road surface, modes of congestion and movement, variability of heights and directions of movement, atmospheric conditions, etc.). Among the already existing means of monitoring liquid fuel consumption with the required accuracy (error 1-2%), volumetric fuel consumption sensors are noted, but the above drawbacks are still preserved in this case. In this article, the authors propose a method and means for monitoring liquid fuel consumption based on an original solution using the principle of optimal discretization of equal portions of fuel, which are taken into account by the supply cycle counter. Conducted preliminary experimental studies have shown the promise of these methods and means for monitoring the consumption of liquid fuel on a vehicle.
