TBN Measurement Process in Used Oil

This video tutorial explains how to determine the Total Base Number (TBN) value of used oil. It covers the process of obtaining two key values: the reference value from new oil and the test value from used oil. The tutorial provides detailed steps for setting up the equipment, measuring the reference value, and testing the used oil. It also explains how to calculate TBN depletion by comparing the reference and test values. The video emphasizes the importance of accurate measurements and proper handling of equipment to ensure reliable results.

What are the two key values needed to determine the TBN of used oil?

• Color of the oil and smell of the oil

• Reference value from new oil and test value from used oil

• Density of the oil and viscosity of the oil

• Temperature of the oil and pressure of the oil

What is the first step in determining the reference value of new oil?

• Press the button marked zero

• Place the cell onto the console and remove the end cap

• Fill the TBN cell with oil

• Shake the reagent C bottle

How much oil should be added for a TBN of 20 to 40?

• 10 mL

• 5 mL

• 2.5 mL

• 7.5 mL

Why is it important to shake the cell vigorously?

• To make sure the test works correctly

• To mix the oil with the reagent

• To ensure the oil is evenly distributed

• To prevent the transducer from being damaged

What should be done after recording the reference value for new oil?

• Test the used oil for TBN depletion

• Dispose of the oil

• Clean the TBN cell

• Replace the reagent C bottle

What is the purpose of entering the reference value and new oil TBN into the unit?

• To calculate the density of the oil

• To measure the temperature of the oil

• To determine the viscosity of the oil

• To calculate the used oil TBN

Which keys are used to enter the reference value into the unit?

• Shift and control keys

• Speed and arrow keys

• Enter and escape keys

• Function and alt keys

What is the final step in the TBN measurement process?

• Press the button marked zero

• Read the used oil TBN

• Shake the reagent C bottle

• Fill the TBN cell with oil

What is the significance of the test value obtained from used oil?

• It indicates the density of the oil

• It is used for calculating TBN depletion

• It measures the temperature of the oil

• It determines the color of the oil

What is the main focus of the TBN measurement process?

• To assess the color of the oil

• To measure the temperature of the oil

• To calculate the used oil TBN

• To determine the viscosity of the oil
