STUDY OF THE SYNTHETIC GEAR OILS PERFORMANCEPROPERTIES DURING BUS OPERATION

Abstract

The purpose of this work is to study the kinematic viscosity and flash point in an open crucible of synthetic
transmission oils with an increase in the MAZ-215 buses mileage.

The scientific novelty of the work is in obtaining new experimental data on changes in the kinematic viscosity and
flash point in an open crucible of synthetic transmission oils with an increase in the bus mileage.

The introduction contains brief information on the requirements for kinematic viscosity and flash point in an open
crucible of synthetic transmission oils used in MAZ-215 model buses.

The main part describes the methodology for conducting research to determine changes in kinematic viscosity at
a temperature of 100 °C and flash point in an open crucible of transmission oils, depending on the vehicle mileage. It has
been found that a minimal decrease in kinematic viscosity at a temperature of 100 °C after a vehicle mileage of
195 thousand km is observed when using synthetic transmission oil brand Liqui Moly Vollsynthetisches Getriebeoil SAE
75W-90. It has also been established that synthetic transmission oils of Castrol Syntrans Multivehicle SAE 75W-90 and
Liqui Moly Vollsynthetisches Getriebeoil SAE 75W-90 brands can be used as transmission oils for MAZ-215 buses due to
their high performance properties.

The results of the research will be useful to mechanical engineers when choosing brands of synthetic transmission
oils in order to increase the reliability and operability of the main buses transmission components.
