What type of diesel is it? Comprehensive analysis of diesel classification and applicable scenarios

As an important fuel type, diesel is widely used in transportation, industrial production, agricultural machinery and other fields. Different types of diesel are suitable for different environments and equipment. Understanding the classification standards and characteristics of diesel is crucial to the correct selection of fuel. This article will give you a detailed analysis of diesel model classification, performance indicators and applicable scenarios.

1. Diesel model classification standards

According to the national standard GB 19147-2016, vehicle diesel is divided into 6 brands based on freezing point. Each brand of diesel is suitable for different temperature environments. Here is a detailed breakdown of diesel models:

2. Main performance indicators of diesel fuel

The quality of diesel fuel not only depends on the model, but also is closely related to its various performance indicators. The following are the main performance indicators of diesel and their significance:

3. How to choose the appropriate diesel model

When choosing a diesel model, you should consider the following factors:

1.local climate conditions: Select the diesel model based on the lowest temperature. Generally, the cold filtering point of the diesel should be 4-6°C lower than the local lowest temperature.

2.Engine type: Different engines have different requirements for diesel. High-speed diesel engines usually require higher quality diesel.

3.economic considerations: Although low-grade diesel is cheaper, it is not suitable for low-temperature environments and may cause the engine to fail to start.

4.Environmental requirements: Urban areas should give priority to National VI diesel fuel with lower sulfur content.

4. Frequently Asked Questions about Diesel Use

1.Can different types of diesel be mixed?Adjacent brands of diesel can be mixed during the transition season, but it is not recommended to mix diesel of different brands for a long time.

2.Why does diesel wax form at low temperatures?When the temperature is lower than the cold filtering point of diesel, the wax in it will crystallize out, causing the filter to become clogged.

3.How to judge diesel quality?High-quality diesel should be clear and transparent, without obvious suspended solids and sediments, and be light yellow or light green in color.

5. Latest diesel market trends (hot spots in the past 10 days)

1.International oil price fluctuations: Affected by geopolitical factors, international crude oil prices have fluctuated upward recently, driving up the wholesale price of diesel.

2.Impact of new energy vehicles: As the number of electric vehicles increases, the growth rate of diesel demand in some areas has slowed down, but the freight and construction machinery fields still maintain stable demand.

3.Promotion of National VI Standards: National VI standard diesel is fully supplied nationwide, and the sulfur content is further reduced to less than 10ppm.

4.Biodiesel development: Many places are piloting the promotion of biodiesel, and gas stations in some areas have begun to supply B5 biodiesel (containing 5% biomass content).

Conclusion

The correct choice of diesel model is crucial to ensure normal engine operation and extend the service life of equipment. Users should choose appropriate diesel products based on the actual use environment and equipment requirements. At the same time, with the improvement of environmental protection requirements, diesel standards will continue to be upgraded in the future, developing in a cleaner and more efficient direction.
