Abstract

The article explores the possibilities of increasing the efficiency of automotive equipment by modernizing the diesel engine power supply system to ensure its operation according to the gas-diesel cycle. The prospects for using natural gas as an alternative component of motor fuel are considered, which allows reducing diesel fuel consumption, reducing the cost of operating vehicles and increasing their fuel efficiency. The principles of operation of diesel engines with combined fuel supply are analyzed, the design features of the standard power supply system are determined, and the advantages and possible limitations of using the gas-diesel operating mode are assessed. An analysis of modern technical solutions for the conversion of diesel engines proposed by domestic and foreign developers is performed. It is established that the implementation of a modernized power supply system will contribute to increasing the fuel efficiency of automotive equipment, reducing the negative impact on the environment by reducing harmful emissions and improving the technical and economic performance of vehicle operation, in particular in the conditions of the agro-industrial complex.
