DEVELOPMENT OF A FUEL HEATING SYSTEM FOR THE AGRICULTURAL AUTOMOTIVE DIESEL ENGINES USING EXHAUST GASES

Abstract

The article provides an analysis of the operation of automotive vehicles with a diesel engine in the cold season. The technical means used to maintain the optimal thermal regime of the diesel fuel system under low-temperature conditions are considered. The relevance of research aimed at improving the fuel heating system using exhaust gases is substantiated. A method for substantiating the parameters of the fuel heating system in the tank using exhaust gases and equipment used in experimental studies is proposed. This article presents conclusions derived from theoretical analysis and practical experiments, based on which a design and optimal parameters of the fuel heating system elements are proposed. It includes dependencies of fuel heating time in the fuel tank on engine operating mode, fuel mass in the tank, and ambient air temperature.

Research tests have established that the equipment of automotive vehicles with the proposed fuel heating system during operation in the cold season contributes to an increase in the average readiness coefficient of the vehicle from 0.81 to 0.87. The research findings can be applied when using automotive vehicles with a diesel engine in the winter season to improve their technical characteristics.
