The efficiency of using a gas-diesel power plant in vehicles

What is it about?

This article discusses the topical issue of efficient use of fuel to power the power plant of a vehicle. The work is devoted to the development of a vehicle (DV) with a hybrid gas-diesel power plant. To reduce the cost of fuel, a rational solution is the installation of a power plant with a gas-diesel power supply system. The arguments substantiating the need for the development of the use of a gas-diesel internal combustion engine (ICE) are presented. The analysis of the fuel mixture, as well as the pricing policy of the fuel market, was carried out. The development of a gas-diesel type of power plant is relevant to reduce material costs compared to a vehicle with a diesel or gasoline engine. In addition to using two different types of fuel, the paper describes the use of an electric motor. The combined use of a thermal internal combustion engine and an electric motor made it possible to design a hybrid power plant that allows you to operate a mainline tractor with the lowest fuel costs. The purpose of the work is to ensure a reduction in material fuel costs when transporting various goods by means of mainline tractors. The KamAZ mainline truck tractor was chosen as the object of the study. The subject of scientific research is an assessment of the economic feasibility of using hybrid power plants for mainline cargo transportation. The article provides a calculation of fuel costs during operation and its results. The dependences of the change in the torque of the engine and its effective efficiency are also given. The final part provides practical recommendations on the use of a hybrid power plant with a gas-diesel power supply system.
