Janosko I., Polonec T., Lindak S., 2014. Performance parameters monitoring of the hydraulic system with biooil . Res. Agr. Eng., 60 (Special Issue): S37–S43. In environmental terms, hydraulic fluids used in the hydraulic system of municipal vehicles represent problems related to a potential leakage from the system into the environment and the subsequent contamination of groundwater and soil. More environment-friendly way is to use green hydraulic fluids that are biodegradable in accidents . This paper aims to investigate the possibilities of biodegradable oil application and its adaptation in the hydraulic systems of mu nicipal vehicles by monitoring the impact of the bio-oil Mobil EAL 46 ESSO on the performance parameters as flow, efficiency, durability, etc. Hydraulic pump revolutions were measured using a non-contact sensor based on the principle of magnetic induction change. Method of tightness monitoring was used to achieve results for functionality and wear of the hydraulic system. During 600 h of the test period no significant deterioration of performance parameters was detected. Results are useful for companies involved in waste collection.
