【 摘 要 】

The article presents the results of testing four engines working in two groups. The first group was powered by natural gas, the second was biogas. In each of the groups, one of the engines was loaded constant at the level of about 80% of the maximum power (with a variation of ± 5%) the other in a variable manner (in the range of 40-70%). After the cycle, the viscosity, acid number, base number, chloride content, silicon content and calcium and phosphorus content were tested in the oil. It was found that the acid number for all examined cases did not differ significantly. Like the content of calcium and phosphorus. The content of silicon in the oil was higher for the engine that was permanently loaded but produced more energy in the tested period (132 MWh) regardless of the type of fuel. The higher viscosity value was found in the oil of the engine loaded in a variable manner but producing less energy (66 MWh). The value of the basic number of oil had a higher value for the engine loaded in a uniform manner.
