Abstract
The article provides a closer look into the quality properties of fuels, analyses the merits and demerits of using biocomponents in petrol and diesel and overviews the ways of improving the quality of fuels. Work carried out by the authors covers the determination of the basic quality properties (density, kinematic viscosity and flash point) of petrol, diesel, methanol, ethanol, buthanol as well as rape methyl and rape ethyl esters. The paper investigates how these qualities influence the operational performance of the engine and puts forward the age‐dependence analysis of diesel quality properties.
Highlights
In the context of increasing requirements for fuels, including requirements related to their environmental impact, the issue of the quality of fuels is gaining more and more importance
Particular consideration in updating the standards of quality is given to the environmental performance of fuels including such properties as the content of sulphur, polycyclic aromatic hydrocarbons and other contaminants found in diesel and petrol
The recent focus with a view to establishing more stringent requirements is mainly placed on the environment-related properties of fuels such as the content of sulphur, polycyclic aromatic hydrocarbons and other contaminants found in diesel and petrol
Summary
In the context of increasing requirements for fuels, including requirements related to their environmental impact, the issue of the quality of fuels is gaining more and more importance. The quality of fuels is subject to compliance with standards the level of which is being enhanced on an ongoing basis. Particular consideration in updating the standards of quality is given to the environmental performance of fuels including such properties as the content of sulphur, polycyclic aromatic hydrocarbons and other contaminants found in diesel and petrol. With a view to ensuring the conformity of fuels to new requirements, it is necessary to undertake a technological upgrade of oil refineries, namely to modernize the equipment of petrol chemical processing, to install or upgrade desulphuring equipment etc (Lingaitis and Pukalskas 2008; Butkus et al 2007). Research into the quality of fuels and their biocomponents presented by another researchers, for example: Baltėnas et al (1998); Pukalskas (2002); Jeuland et al (2004); Li et al (2005); Makarevičienė et al (2005); Thirouard and Cherel (2006); Agarwal (2007); Albrecht et al (2007); Arsie et al (2007); Butkus et al (2007); He et al (2003); Lebedevas et al (2007a and 2007b); Raslavičius and Markšaitis (2007); Al-Hasan and Al-Momany (2008); Boychenko et al (2008); Lingaitis and Pukalskas (2008); Lebedevas and Lebedeva (2009); Raslavičius (2009); Török (2009); Petrović et al (2009) and others
