What kind of diesel is used in construction machinery?
As an important tool for infrastructure construction, construction machinery mainly relies on diesel as its power source. Different types of construction machinery also have different requirements for diesel. Choosing the right diesel can not only improve mechanical efficiency, but also extend the life of the equipment. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the types of diesel commonly used in construction machinery and their characteristics.
1. Commonly used diesel types for construction machinery
According to national standards and actual needs of construction machinery, diesel is mainly divided into the following categories:
| Diesel type | Applicable scenarios | Features |
|---|---|---|
| No. 0 diesel | Normal temperature area (used in summer) | Low freezing point, suitable for high temperature environments |
| -No.10 diesel | Low temperature areas (for winter use) | Strong anti-freeze performance to prevent wax formation |
| -No. 20 diesel | Severe cold areas (extremely cold environments) | Good low-temperature fluidity, avoiding startup difficulties |
| National VI standard diesel | Nationwide (high environmental requirements) | Low sulfur content, reducing exhaust pollution |
2. Key factors in selecting diesel for construction machinery
1.ambient temperature: Different grades of diesel are suitable for different temperature environments. For example, No. 0 diesel is suitable for summer use, while No. 20 diesel is suitable for severe cold areas.
2.Mechanical model: Some high-end engineering machinery has higher requirements on diesel cleanliness and combustion efficiency, so high-quality diesel must be selected.
3.Environmental requirements: With the tightening of environmental protection policies, National VI standard diesel has gradually become the mainstream, which can effectively reduce exhaust emissions.
3. Recent hot topics: The impact of diesel price fluctuations on the construction machinery industry
According to the analysis of the entire network data in the past 10 days, diesel price fluctuations have become a hot topic in the construction machinery industry. The following is a comparison of diesel prices in some regions:
| area | Diesel type | Price (yuan/liter) | Increase or decrease |
|---|---|---|---|
| Beijing | National VI 0 diesel | 7.45 | ↑0.5% |
| Shanghai | National VI-10 diesel | 7.68 | ↓0.3% |
| Guangzhou | National VI-20 diesel | 7.92 | ↑1.2% |
Rising diesel prices may lead to an increase in the operating costs of construction machinery, and some companies have begun to explore new energy alternatives, such as the promotion of electric construction machinery.
4. How to use diesel correctly to extend the life of construction machinery
1.Replace diesel filter element regularly: Prevent impurities from entering the engine and causing wear.
2.Choose a regular gas station: Ensure diesel quality and reduce the risk of mechanical failure.
3.Change diesel grade according to season: Use low pouring point diesel in winter to avoid starting difficulties.
5. Future Trend: Coexistence of New Energy and Diesel
With the advancement of environmental protection policies, new energy engineering machinery (such as electric excavators and hydrogen loaders) are gradually entering the market. But in the short term, diesel will still be the main source of power for construction machinery. The industry needs to balance costs and environmental protection and gradually realize energy transformation.
Summary: The choice of diesel for construction machinery needs to comprehensively consider the environment, machinery model and environmental protection requirements. The recent fluctuations in diesel prices have attracted industry attention. In the future, new energy and diesel will jointly promote the development of the construction machinery industry.
