The article discusses modern approaches to improving the efficiency of machine-tractor units by optimizing fuel consumption using a fuel component mixer. Rising fuel prices and tightening environmental requirements encourage the search for new technologies that ensure economical and environmentally friendly operation of agricultural machinery. One of the promising solutions is the use of power systems with a fuel mixer, which allows you to adjust the ratio of fuel mixture components in real time, taking into account the load on the engine, its speed and temperature regimes.
The article analyzes in detail the influence of various parameters of the fuel mixture on the efficiency of the engine and its economy. A mathematical model of the fuel mixing process is proposed, which takes into account the physicochemical properties of the components, as well as a control algorithm that allows adaptively adjusting the fuel mixture to achieve optimal consumption indicators. Computer modeling of the engine operation using different fuel mixture compositions was carried out, which made it possible to assess the influence of the mixer on the dynamic characteristics of the unit and fuel economy.
The results of the research show that the use of a fuel mixer allows you to reduce costs by 10-15% without losing power, while maintaining the stability of engine operation. In addition, it was possible to reduce emissions of harmful substances into the atmosphere, which contributes to increasing the environmental friendliness of agricultural work. The article also provides recommendations for setting up and operating a fuel mixing system to achieve maximum efficiency.
The proposed approach may be useful for engineers involved in the development of fuel systems, as well as for farmers seeking to reduce operating costs. The results obtained contribute to the further development of energy-efficient technologies in agricultural machinery.
