3. Analysis of key fuel-saving technologies
1.Hydraulic system optimization: Komatsu’s CLSS system saves 15% more energy than traditional systems by reducing pressure loss in the hydraulic circuit.
2.Intelligent power matching: Sany DOMCS technology can automatically adjust the engine speed according to the load, saving 8-12% of fuel in actual measurements.
3.Hybrid solution: Volvo EC220D’s regenerative braking system can save fuel by up to 20%.
4. Comparison of user measured data
| test items | Komatsu PC210 | SANY SY215 | Carter 320GC |
|---|---|---|---|
| Earthmoving work (8h) | 103L | 98L | 112L |
| Crushing operation (8h) | 117L | 109L | 125L |
| Comprehensive fuel consumption index | 1.05 | 1.00 | 1.12 |
5. Purchase suggestions
1.200 hour rule: If the annual use exceeds 200 hours, it is recommended to choose high-end fuel-saving models such as Sany/Komatsu, otherwise ordinary models are more cost-effective.
2.Working condition adaptation: Sany SY215 is preferred for earthmoving operations, Volvo EC220D is selected for crushing operations, and Komatsu PC210 is considered for comprehensive working conditions.
3.Note on used equipment: Only National IV equipment produced after 2018 has the latest energy-saving technology, and the second-hand market needs to check the EPA certification.
6. Opinions of Industry Experts
The latest report from the China Construction Machinery Association points out: "The price premium of fuel-saving models in 2024 will be about 8-15%, but the cost can be recovered through the difference in fuel costs within 2 years. The intelligent energy-saving systems of Sany and Komatsu can reduce the total ownership cost by 12-18%."
The data in this article combines the actual measurement reports released in the past 10 days by professional platforms such as Douyin #fuel-saving excavator challenge, Toutiao hot list, and EquipmentWorld. It is recommended that users choose the most suitable fuel-saving solution based on actual working conditions and budget.
