What oil should be added to the excavator? Comprehensive analysis of fuel selection and maintenance guide
Recently, the topic of fuel selection for construction machinery has sparked heated discussions on major forums and social media. In particular, excavators are core construction equipment, and their fuel selection is directly related to equipment performance and cost of use. This article will combine the hot discussions on the entire network in the past 10 days to present you a complete set of solutions for excavator fuel selection in a structured manner.
1. Current status of fuel usage in construction machinery in 2023
| Fuel type | market share | Average price (yuan/liter) | Applicable models |
|---|---|---|---|
| No. 0 diesel | 68% | 7.2 | Small and medium excavators |
| -No.10 diesel | 25% | 7.5 | Used in northern winter |
| biodiesel | 5% | 6.8 | New environmentally friendly model |
| synthetic diesel | 2% | 9.3 | High-end imported equipment |
2. Analysis of core elements of fuel selection
According to the latest "2023 Construction Machinery Fuel Guide" released by the Society of Mechanical Engineers, the following key factors need to be considered when selecting excavator fuel:
| Considerations | Specific requirements | Recommended plan |
|---|---|---|
| ambient temperature | Use No. 0 diesel oil at ＞4℃, use No. 10 diesel oil at -5 to 4℃. | Change oil seasonally |
| Engine model | National III/National IV/National V standards correspond to different sulfur content requirements | View engine nameplate |
| work intensity | It is recommended to use high-quality diesel for continuous operation | Choose a regular gas station |
| cost control | Biodiesel can save 5-8% on fuel costs | Mixed use plan |
3. Answers to recent hot questions
1."Can I use gasoline in an excavator?"Absolutely prohibited! The compression ratio of diesel engines (16:1 to 22:1) is much higher than that of gasoline engines. Using gasoline will cause knocking and seriously damage the engine.
2."Is there any impact of using winter diesel in summer?"In winter, the freezing point of diesel is low but the calorific value is slightly lower. Use in summer will cause the power to drop by 3-5%. It is recommended to replace it according to seasons.
3."Are the oil products at private gas stations reliable?"Recent spot checks by market regulatory authorities in many places show that the pass rate of privately owned stations is 82%, 9 percentage points lower than that of state-owned stations. It is recommended to choose state-owned oil stations during the warranty period of key components.
4. Golden Rules of Fuel Maintenance
| maintenance items | operating standards | cycle |
|---|---|---|
| Fuel filter replacement | Replace coarse and fine filters at the same time | 500 hours |
| Fuel tank cleaning | Use professional cleaning agents | 2000 hours |
| Oil line inspection | Check fuel pressure | per month |
| Moisture discharge | Open the valve at the bottom of the tank | weekly |
5. New trends in fuel technology in 2023
1.Hydrogenated vegetable oil (HVO): Nordic brand is the first to promote it, which can reduce carbon emissions by 80%, but the price is 1.5 times that of ordinary diesel.
2.Hybrid system: Japanese manufacturers launch hybrid excavators, which reduce fuel consumption by 40%, but increase purchase costs by 25%.
3.Intelligent oil monitoring: Real-time analysis of fuel quality through IoT sensors to provide early warning of oil line problems.
Choosing the right fuel and doing good maintenance can not only extend the service life of the excavator, but also significantly reduce operating costs. It is recommended that machine owners establish a complete oil usage file to record the brand, label and equipment operating status of each refueling, so as to provide data support for subsequent optimization.
