Research on the quality of diesel fuel provided by LLC Ferronordic Trading House

Abstract

Ferronordic is the official dealer for Volvo Construction Equipment, Dressta, Mecalac and Rottne. In addition to sales and after-sales support for Volvo Construction Equipment, the company is a dealer for servicing Volvo and Renault Trucks, as well as a dealer for Volvo Penta for servicing industrial and marine engines in some regions of Russia. The company collaborates with other well-known brands and several suppliers of attachments. The Swedish concern Volvo Group supplies to the Russian market trucks equipped with diesel engines with Common Rail injection system, as well as with pump nozzles. Diesel mechanical and electronic pump nozzles perform timely and metered injection of the working mixture into the combustion chambers of the cylinders of a diesel engine. The mechanical nozzles are driven by a high-pressure fuel pump, while the electronic ones are controlled by the Common Rail electronic injection system and are constantly under intense mechanical stress. Poor quality diesel fuel leads to: loss of power, lack of traction and instability of the engine; overexpenditure and fuel leakage from sprayers; change in spray angle and time; change in the amount of injected mixture; the appearance of knocks and noises, black and bluish smoke during exhaust. The results of research work on the study of the quality of diesel fuel of the company LLC Ferronordic Trading House are presented. The physicochemical properties of diesel fuel were studied experimentally, such as: density, fractional composition, mass fraction of sulfur, mass fraction of water, flash point, limiting filterability temperature and cloud point.
