The detection project of diesel engine oil for internal combustion locomotives is as follows:

1. Viscosity: Viscosity is a measure of the oil's resistance to flow. It affects how effectively the oil can lubricate and protect the engine.

2. Flash Point: The flash point indicates the temperature at which the oil gives off vapor that can ignite in the presence of an ignition source.

3. Pour Point: The pour point is the lowest temperature at which the oil will flow. It is important for cold start-ups in winter conditions.

4. Total Base Number (TBN): TBN is a measure of the oil's ability to neutralize acids and prevent corrosive wear in the engine.

5. Total Acid Number (TAN): TAN measures the acidity of the oil, which can indicate the presence of contaminants or degradation.

6. Water Content: Detecting water content is important as it can lead to corrosion and reduced lubricating properties.

7. Insoluble Content: Insoluble content in oil can lead to sludge formation and engine deposits.

8. Sulfur Content: Sulfur content affects emissions and can lead to catalyst poisoning in emissions control systems.

9. Wear Metal Analysis: Analyzing wear metals provides insight into the wear rates of engine components.

10. Oxidation Stability: Oxidation stability measures the oil's resistance to breakdown due to exposure to oxygen at high temperatures.

11. Particle Count: Counting particles in the oil can indicate levels of contamination and wear within the engine.

12. Moisture Content: Moisture can accelerate oil degradation and lead to corrosion in the engine system.
