“…The IV indicates the fuel unsaturation content and hence the tendency of the fuel to oxidize, which favors the occurrence of polymerization and formation of gum deposits in diesel cycle engines. 51,[55][56][57] Figure 3 presents the values of HC emissions (in the form of CH 4 ) in % m/m of the base fuels and their respective formulations with MR and ER soybean biodiesel. It should be noted that diesel fuel with CN 50 produces lower HC emissions than diesel with CN 45.…”

An evaluation was made to determine the effect of the glycerides presence resulting from the incomplete conversion of soybean biodiesel produced via alkaline catalysis and ethylic route on engine performance, and emissions in formulations containing 10 and 20% (m/m) of biodiesel used as additives in base diesel with low sulfur content and cetane ratings of 45 and 50. By way of comparison, similar formulations were used with soybean biodiesel methyl route with low concentration of glycerides. Tests on a diesel cycle engine with a mechanical fuel injection system indicated that the presence of glycerides decreases the volatility of biodiesel and increase the cetane number of fuels. The higher the cetane number, the higher the particulate matter emissions and the lower the unburned hydrocarbon emissions. Formulations with cetane number 50 showed higher emissions of particulate matter. The presence of glycerides in biodiesel reduces the fuel's vapor pressure, thereby increasing the cetane number and emissions of particulate matter and lower emissions of unburned hydrocarbons. The specific consumption of fuels formulated with biodiesel increases due to its lower enthalpy of combustion and to the presence of glycerides in fuels formulated with soybean biodiesel produced via the ethanol route.

“…Though natural triglycerides are rapidly biodegradable and highly effective lubricants, their thermal, oxidation and hydrolytic stability is limited, though some of the oils such as rapeseed and sunflower oils are used directly as lubricants in the European countries. They are limited to low thermal stress applications like mold release and chain saw oils 1 .…”

This paper presents the evaluation of a newly developing synthetic-based hydraulic fluid MOL Farm UTTO Synt, developed by MOL Group, Hungary. The fluid was subjected to a laboratory test by using a gear hydrostatic pump UD 25, which is used in the latest Zetor Fortera tractors. During the test, flow values were statistically evaluated and graphically displayed in the form of flow characteristics and the loss of flow efficiency. On the basis of laboratory test results, it can be concluded that the newly developing fluid meets the specified requirements and it is possible to continue in testing under operating conditions. Keywords: flow efficiency, hydrostatic pump, synthetic-based hydraulic fluid Abstrakt Príspevok je zameraný na hodnotenie novovyvíjanej hydraulickej syntetickej kvapaliny MOL Farm UTTO Synt, vyvíjanej spoločnosťou MOL Group, Maďarsko. Kvapalina bola podrobená laboratórnemu testu za použitia zubového hydrogenerátora UD 25, ktorý sa používa v najnovších traktoroch Zetor Forterra. Počas skúšky boli hodnoty získaných prietokov štatistický spracované a následne graficky vyhodnotené vo forme prietokových charakteristík a poklesu prietokovej účinnosti hydrogenerátora. Na základe výsledkov laboratórnej skúšky je možné konštatovať, že novovývíjaná kvapalina vyhovuje stanoveným požiadavkám a je možné pokračovať v skúškach v prevádzkových podmienkach.
