Quality Type

Diesel fuel quality can be considered from many different points of view. Fuel producers, fuel consumers, and ecologists have their own ideas. In this paper, a sensor of diesel fuel quality type, and fuel condition that is oriented to the fuel’s consumers, is presented. The fuel quality types include premium, standard, and full bio-diesel classes. The fuel conditions include fuel fit for use and fuel degraded classes. The classes of fuel are connected with characteristics of engine operation. The presented sensor uses signal processing of an optoelectronic device monitoring fuel samples that are locally heated to the first step of boiling. Compared to previous works which consider diesel fuel quality sensing with disposable optrodes which use a more complex construction, the sensor now consists only of a capillary probe and advanced signal processing. The signal processing addresses automatic conversion of the data series to form a data pattern, estimates the measurement uncertainty, eliminates outlier data, and determines the fuel quality with an intelligent artificial neural network classifier. The sensor allows the quality classification of different unknown diesel fuel samples in less than a few minutes with the measurement costs of a single disposable capillary probe and two plugs.

The physicochemical properties of biodiesel fuels and their blends prepared from four residential waste vegetable frying oils (sunflower (FSME), canola (FCME), mixture of sunflower and rapeseed (FSRME) and corn (FSCME)) were evaluated and measured to determine the best blend. The results indicate that the stability of 10 biodiesel blends was above 10 h for 0-month, meeting the stability requirement regulated in EN 14214:2014 by adding FSCME, which depends on the concentration amount of FSCME. Besides, the results showed that all fuel samples did not meet the requirements of diesel fuel standards. Therefore, automobile gasoline is used as an additive to unmixed biodiesel in various concentrations to reduce the kinematic viscosity, density and cold flow properties. The results indicate that BG85 and BG80 have met the mixed pure biodiesel with gasoline fulfilled diesel fuel quality standard. Therefore, the samples with stability above 10 h were mixed with gasoline in 15% and 20% to reduce the cold flow properties and meet the specifications of the diesel fuel standards. Moreover, the effect of long-term storage on the properties of all samples was investigated under different storage conditions. The results indicate that higher storage temperatures and longer storage periods negatively influenced the properties of the fuel samples.

During the production, transportation, distribution, use or storage of diesel fuel, liquid and solid substances get into it, negatively affecting their operational properties. These substances are called pollutants. At the same time, impurities are removed from the fuel by filtration, dehydration and settling. The total amount is the result of the cleaning process. The performance of the aforementioned tasks of the fuel system is mainly determined by the corresponding physicochemical properties of the diesel fuel. The properties of the fuel that affect the functioning of the fuel system are as follows: masticity, viscosity, density, rheological indicators at low temperatures. Failure to comply with the requirements for oil and the content of impurities in diesel fuel can quickly damage injection equipment, which is sensitive to changes in fuel quality. By nature, contaminants of diesel fuel include: dust particles, water, corrosion products of pipelines and tanks, microorganisms, resinous substances. The requirements for diesel oils contained in the PN-EN 590 standard determine the permissible contamination level. The maximum content of solid pollutants for diesel engines is 24 mg / kg. This value is the amount of solids released when filtering a given amount of fuel through a nitrocellulose filter, the pore size of which is less than 0.8 microns. The fifth edition of the World Fuel Charter, September 2013, contains an additional criterion for the particle size of particulate pollutants. A section introduced concerns particles larger than 4 µm, 6 µm and 14 µm. According to the assumption of the division of molecules into corresponding groups of sizes, the purity of diesel fuel is determined by three numbers. These, in turn, correspond to the number of molecules contained in the above size ranges. TDue to the possibility of microbial growth, filter blocking or increased galvanic corrosion, it is assumed that the water in diesel fuel should not be in a separate phase. The permitted water content in diesel fuel is 200 mg / kg. The release of sulfur compounds into the atmosphere increases the concentration of other toxic components in the exhaust gases of vehicles with compression inflammation engines. Sulfur improves the masticability of diesel fuel, but due to environmental protection, its content is systematically reduced. Modern standards for these fuels allow sulfur content up to 10 mg / kg. The content of impurities can be defined as the volume (v / v) or mass (w / m) fraction of impurities contained in a unit volume or mass of the test liquid. There are many methods for determining the content of various types of impurities, from the simplest - visual, through quantitative and qualitative tests, to chemical tests. Four samples of diesel fuel were tested. Diesel (ON) was the baseline. The rest of the samples underwent an accelerated contamination procedure. The pollutants used in the study were: water, gasoline, solid powder abrasive substances consisting of silicon carbide grains SiC (95 - 98%) and impurities Fe2O3, Al2O3, CaO, SiO2, MnO2, granulation 4.5 μm ± 1%. In a baseline test of unstained diesel fuel, a capture force Poz of 930 N was obtained. Capture occurred after 2 s of the test. The sample, a mixture of diesel and gasoline, showed a slight decrease in Poz strength compared to baseline breakdown. The difference was 3%. The time over which the entrainment was observed was similar to the time taken for the baseline sample. During the examination of a diesel fuel sample contaminated with solid particles of abrasive powder, there was a sharp decrease in the gripping force by as much as 97% relative to the result obtained for the base sample, and the beginning of gripping was less than 0.5 s. Tests with a mixture of diesel fuel and water showed a 15% decrease in gripping force, and the time was also 2 s. After comparing the results obtained, it can be concluded that all the impurities used influenced the force of the gripping load. Different results indicate different degrees of influence of certain pollutants on the makability of diesel oil. KEY WORDS: DIESEL, POLLUTANTS, LUBRICANT PROPERTIES, GRIP, GRIP STRENGTH.
