The influence of the system for processing exhaust gas of tractor diesel engines on the physico-cheical and mechanical properties of engine oil

Analiza stanja motornog ulja u eksploataciji vrlo je značajna za ocjenu stanja ulja, a također i za ocjenu stanja vitalnih dijelova motora, odnosno cijelog motora. Uvođenje sve oštrijih zahtjeva u pogledu smanjenja emisije ispušnih plinova dovelo je kako do „evolucije“ sustava za obradu ispušnih plinova na motorima SUI tako i do zahtjeva o kvaliteti i kemijskom sastavu maziva. Zbog tih razloga je obavljeno ispitivanje dva motorna ulja za poljoprivredne strojeve u primjeni u poduzeću Anagalis d.o.o. Ispitivana su važna fizikalno-kemijska te mehanička svojstva. Ulja su korištena na dva različita sustava obrade ispušnih plinova. Rezultati ispitivanja su pokazali izvanrednu zaštitu motora pri podmazivanju ispitivanim motornim uljem i nešto bolje uvjete rada za traktor sa SCR sustavomAnalysis of the engine oil in exploatation is very significant for the evaluation of oil and also to review the status of the vital parts of the engine, or the entire engine. The introduction of ever more stringent requirements in terms of reducing emissions has led to to the "evolution" of the system for processing exhaust gas to internal combustion engines as well as to the requirements on the quality and chemical composition of the lubricant. For these reasons, the testing done two motor oils for agricultural machinery in the application of the company Anagalis d.o.o. Investigation of important physico-chemical and mechanical properties. Oils are used in two different exhaust treatment systems. The results showed excellent engine protection for engine oil lubrication tested and something better working conditions for the tractor with SCR system
