A comprehensive technical presentation analyzing various methods and techniques for measuring engine oil consumption in both diesel and gasoline engines.
This repository contains a detailed engineering presentation on oil consumption measurement methodologies to accurately quantify and localize oil consumption sources within internal combustion engines.
- Measurement Units & Standards: Grams per kilowatt-hour (g/kWh), liters per 1,000 km, and percentage of fuel consumption
- Exhaust Gas Analysis Methods:
- Calcium trace method for particle analysis
- Sulfur trace method with various detection techniques (FPD, NDIR, coulometric cells)
- Radioactive Tracer Method: Germanium-69 labeling for precise localization of oil consumption in engine components
- Thermogravimetric Analysis (TGA): Quantitative measurement of combustion residues
- Direct Measurement Techniques: Smart oil consumption meter and simplified glass tube pipette methods
- Component Analysis: Identifying oil consumption sources (piston rings, valve guides, turbocharger seals, oil separators)

| Method | Detection Principle | Key Advantage | Key Limitation |
|---|---|---|---|
| Calcium Trace | Particle analysis | No extra engine instrumentation | Requires DPF filter |
| Sulfur Trace | Gas emissions | Real-time measurement capability | Depends on sulfur content |
| Radioactive Tracer | Isotope decay | Precise component localization | Requires specialized equipment |
| Smart Meter | Level sensor + PID | Fully automated | Accuracy affected by oil degradation |
| Glass Tube Method | Direct volume measurement | Low cost, accurate | Manual, not real-time |
