MÁCHAL PAVEL, MAJDAN RADOSLAV, TKÁČ ZDENKO, STANČÍK BOHUSLAV, ABRAHÁM RUDOLF, ŠTULAJTER IVAN, ŠEVČÍK PETER, RÁŠO MILAN: Design and verifi cation of additional fi ltration for the application of ecological transmission and hydraulic fl uids in tractorc.Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 5, pp. 1305-1311 This contribution presents the design and function verifi cation of additional fi ltration. It is intended for the common transmission and hydraulic oil fi lling of tractors. The main role of this fi ltration concept is to ensure a high level of oil cleanness as a condition for the application of ecologic fl uids in tractors. The next one is to decrease the wear of lubricated tractor components, the degradation of oil and eventually to extend the interval of oil change. The designed additional fi ltering is characterized by ease installation through the use of quick couplings and hoses to the external hydraulic circuit. Therefore, the fi ltration is suitable for various tractor types. Filter element has been designed with the fi lter ability 1micron and the ability to separate to 0.5 dm 3 of water from oil. Function of additional fi ltration was verifi ed during the 150 engine hours of tractor operation. During this time period the oil contamination was evaluated on the basis of chemical elements content such as Fe, Cu, Si, Al, Ni, Mo and Cr. The additive concentration was evaluated on the basis of chemical elements content such as Ca, P and Zn. During the test operation of tractor the concentration decrease of chemical elements reached the values 25.53 % (Fe), 23.53 % (Si), 25 % (Al) and 5.5 % (Cu). The decrease of additive concentration reached only medium level (6.6 %). Therefore, the designed additional fi ltration doesn't remove additives from oil. Based on the evaluation of the content of chemical elements (that representing contamination and additives), we can say that the designed fi ltering method is suitable for use in agricultural tractors. oil contamination, additives, biodegradable oil, spectroscopy, environmental protection Fluids that are used in common transmission and hydraulic systems of tractors are exposed to specifi c conditions characteristic for agricultural production. These oils must perform all requires functions in the transmission and hydraulic system of tractor and they also must be resistant to oxidation and thermal degradation. Agricultural tractors o en operate in dusty and humid environment which eff ects oil fi ll contamination. In addition, the oil fi lls are polluted by the amount of wear particles mainly from the transmission system, which carries the full power of the engine to the wheels of the tractor.

Analysis of Degradation of Motor Oils Used in ZETOR Tractors

“…They propose to perform a further research based on which the oil change interval can be optimized with respect to operational conditions of a device. Máchal et al (2013) dealt with a proposal of additional filtration of hydraulic oils used in tractors which would help to decrease a level of wear of lubricated parts of the tractors and degradation of the oil and also to extend the oil interval change. Kosiba et al (2013) presented results of research of properties of hydraulic ecological oil MOL Farm UTTO Synt in operational conditions when used in Zetor Forterra 11441 tractor.…”

Evaluation of new biodegradable fluid on the basis of accelerated durability test, FTIR and ICP spectroscopy

“…On the basis of the measured values of flow efficiency decrease during the laboratory test, it can be stated that the 1,000,00 Table 2 to be continued hydrostatic pump had very good operational parameters when it was working with the newly developed synthetic biodegradable fluid because the resulting value of flow efficiency decrease did not exceed the limit value 20% specified by the manufacturer Máchal et al 2013). …”

Application of FTIR Spectrometry Using Multivariate Analysis for Prediction Fuel in Engine Oil

“…Veselá et al (2014) evaluated the effect of biofuels E85 and fuel with 95 octane values types on the quality and purity of engine oil Mobil 10W-40 used in three types of cars. Fluid purity is also one of the important features in the entire process (Máchal et al, 2013). Hönig and Hromádko (2014) analyzed the impact of biofuels on the quality of oil used to fill diesel engines, and established an optimal oil change interval.…”
