What kind of diesel does an excavator use? Comprehensive analysis of diesel fuel selection and use guide
With the widespread application of construction machinery, excavators are one of the core equipment, and their fuel selection directly affects work efficiency and equipment life. This article combines hot topics and industry data from the entire Internet in the past 10 days to provide you with detailed answers to the selection criteria for excavator diesel, and attaches a structured comparison table.
1. Why is diesel selection important for excavators?
1. Engine protection: Inferior quality diesel can cause carbon deposits and clogged fuel injectors.
2. Work efficiency: Appropriate diesel grade can ensure stable power output
3. Economic cost: Correct choice can reduce fuel consumption by 10-15%
4. Environmental requirements: Diesel that meets National VI emission standards reduces tail gas pollution
2. Four key indicators of excavator diesel
| indicator | Standard requirements | FAQ |
|---|---|---|
| cetane number | ≥49 (National VI standard) | Low values can cause startup difficulties |
| Sulfur content | ≤10ppm | High sulfur corrodes engine parts |
| freezing point | Choose according to ambient temperature | Low temperature is prone to condensation and blockage |
| Moisture impurities | ≤0.005% | Accelerate oil pump wear |
3. Recommendations for diesel fuel selection in different seasons
| ambient temperature | Recommended label | Applicable areas |
|---|---|---|
| >4℃ | 0#diesel | South China |
| -5℃～4℃ | -10# diesel | Yangtze River Basin |
| -14℃～-5℃ | -20# diesel | North China |
| ＜-14℃ | -35# diesel | Northeast/Northwest |
4. Performance comparison of mainstream diesel brands in 2023
| brand | cetane number | Sulfur content | Price (yuan/liter) | User ratings |
|---|---|---|---|---|
| Sinopec | 51 | 8 ppm | 7.2 | 4.8/5 |
| PetroChina | 50 | 9ppm | 7.1 | 4.7/5 |
| Shell | 52 | 5ppm | 7.5 | 4.9/5 |
| Private petrol station | 46-49 | 15-30ppm | 6.8 | 3.5/5 |
5. Five things to note when using diesel
1.It is strictly prohibited to mix gasoline: Will cause detonation and damage the engine
2.Change filters regularly: Recommended to replace every 500 hours
3.Choose a regular gas station: The pass rate of small oil stations is only 68% (2023 quality inspection data)
4.Change oil in advance in winter: Complete label switching before the temperature drops sharply
5.Fuel tank management: Keep the oil content above 1/3 to prevent condensation
6. Expert advice:According to the latest report of the China Construction Machinery Association, the use of National VI standard diesel from formal channels can extend the overhaul cycle of excavators by 2,000-3,000 hours, saving about 12,000-18,000 yuan in annual maintenance costs.
Conclusion:The correct selection of diesel fuel is the basis for efficient operation of the excavator. It is recommended that machine owners establish fuel usage files, record actual consumption data of different grades of diesel, and find the optimal fuel solution through data analysis.
