Krakowski Rafał

Combustion Engines

2021

R. 60, nr 4

8--11

In the article, base number as a parameter characterizing the washing and dispersing abilities of engine oil were characterized. Next, the influence of additives enriching engine oils on the natural environment was described. In the further part of the article, the research methodology, applied oil samples with additives of effective microorganisms and silver solution, both for fresh oil and used oil were presented. In addition, the measuring test stand with instrumentation and measuring device was shown. In the main part of the article base number value for fresh and used oil compared to oils with the addition of microorganisms and a solution of silver and colloidal silver were described. Next the analysis of the influence of these additives on the base number value was made. The article was completed conclusions.
