       In all ages, science has been the foundation of progress. The knowledge gained allowed humanity to develop both spiritually and materially, becoming the productive force of society. At the same time, as a rule, the time between a scientific discovery and its practical implementation has always been a considerable period. The discovery of photography has gone this way in more than a hundred years, a telephone in about sixty years, a radar in fifteen, and a nuclear reactor in ten. The developments of current scientists will also be in demand, most likely, after a while.

      A lot of research data has been published in the modern literature on the possibility of using mineral, vegetable, and synthetic fuels in internal combustion engines. But most studies do not solve the main problem — cars were not originally created for alternative fuels. In order to use other types of energy sources, a system must be created that can adapt to their properties and ensure their use.

       — The oil will run out someday, and we must be ready for this. In addition, the entire world community is now talking about environmental issues, so we are developing projects that will be able to replace petroleum fuels, while reducing the environmental impact on the environment. Alternatives to oil have different properties, therefore, for new energy sources it is necessary to create units that will allow fuel to be stored, supplied, and ignited so that the machine can work reliably on it," said Sergey Plotnikov.

      An upgraded diesel power supply system in a tractor or car should solve several tasks. Among them is to efficiently mix the necessary fuel ingredients for each operating mode, ensure the required level of heating of the fuel mixture, adjust the injection angle and fuel dose depending on the operating mode. During the tests, several power system designs were recommended that allow diesel engines to run on various alternative fuels by adjusting the composition and amount of the mixture. All developed designs are protected by patents of the Russian Federation for inventions.

      — My developments and research of my students are aimed at a fairly near future. We are currently developing separate units for storing, supplying, regulating and igniting fuel. And, of course, we check how the engine works when using alternative fuels and new systems, both in bench and in operational conditions.

After warming up, taps are opened to supply alternative fuel or a mixture. The sensors of the upgraded system measure the composition and properties of the fuel and transmit the data to the electronic control unit, which automatically adjusts the fuel supply parameters and operating modes of auxiliary devices.

      For example, a photoelectrocolorimeter determines the composition of a fuel by its density. Based on the composition value, the electronic unit determines the required amount of fuel to be supplied, the moment of fuel supply, the need for heating, and other parameters.

      The use of new systems makes it possible to maintain diesel engine operation at the factory level and even improve some indicators, such as fuel consumption, soot content and toxic components in the exhaust. It should be noted that the upgraded fuel supply systems allow diesel engines to run stably on different types of alternative fuels.

      Tests of the developed systems are carried out at the Belarusian State Agricultural Academy on full-size engines with the participation of Professor Anatoly Kartashevich and his students, and are successfully applied in practice.
