13 gru 2022 · The major physical properties of diesel fuel are: 1. Density. The presence of different classes of hydrocarbons helps to estimate the density of diesel fuel. In diesel fuel, the density increases with the increase in the number of carbon atoms present in it. Thus, the increasing order of density begins with paraffins, naphthenes, and aromatics.
Important properties which are used to characterize diesel fuel include cetane number (or cetane index), fuel volatility, density, viscosity, low temperature operability properties, and sulfur content.
Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel.
Diesel fuel is a complex mixture derived from crude oil through fractional distillation, consisting mainly of aliphatic and aromatic hydrocarbons with a boiling point range of approximately 163–357 °C. It is classified based on the type of engine it fuels, ranging from 1-D to 4-D.
The subject of this review is diesel fuel – its performance, properties, refining, and testing. A chapter in the review discusses diesel engines, especially the heavy-duty diesel engines used in trucks and buses, because the engine and the fuel work together as a system.
In Europe, Fuel Quality Directive 2009/30/EC defines the requirements for basic fuel properties for diesel fuel. European standard EN 590 includes more extensive requirements than Fuel Quality Directive to ensure proper functionality of diesel fuel on market.
15 mar 2018 · The experimental measurements of Diesel fuel properties at high pressures and wide range of temperatures is of increasing interest in engine fuel injection. The measurements were carried out with an Anton Paar DMA HPM vibration tube densimeter.
