What is the engine of Doosan excavator?
In the field of construction machinery, Doosan excavators have won wide market recognition for their excellent performance and reliability. As its core component, the performance of the engine directly determines the working efficiency and stability of the excavator. This article will conduct a detailed analysis around the engine types, technical features and market feedback of Doosan excavators, and present you the latest information through structured data.
1. Doosan excavator engine types and technical characteristics
Doosan excavators mainly use self-developed DL series engines, and some models are adapted to engines from internationally renowned brands. The following is a comparison of the engine configurations of Doosan’s mainstream models that has been hotly discussed on the Internet in the past 10 days:
| model | Engine model | type | Displacement(L) | Power(kW/rpm) | Technical Highlights |
|---|---|---|---|---|---|
| DX220LC-7 | DL08P | turbocharging | 7.9 | 121/2000 | Electronically controlled high-voltage common rail, ECO mode |
| DX380LC-7 | DL13P | Turbocharged intercooler | 12.7 | 212/1800 | Two-stage filtration system, SCR post-processing |
| DX500LC-7 | Cummins QSL9 | High voltage common rail | 8.9 | 253/1800 | Intelligent combustion control, DPF regeneration |
2. Focus on recent hot topics
1.Environmental protection upgrade: According to the latest non-road National IV emission standards, Doosan has upgraded its SCR (selective catalytic reduction) technology across all models, and users have measured nitrogen oxide emission reductions of up to 90%.
2.fuel economy controversy: Measured data from a short video platform shows that the fuel consumption of the DL08P engine in earthmoving operations is 8%-12% lower than that of competing products. However, some users reported that fuel consumption fluctuates greatly during plateau conditions.
3.Repair cost comparison: The following is the engine maintenance cost data discussed on social media in the past 10 days:
| Engine model | Filter element replacement cycle (h) | Oil replacement cost (yuan) | Typical failure rate (%) |
|---|---|---|---|
| DL08P | 500 | 1200-1500 | 1.2 |
| DL13P | 600 | 1800-2200 | 0.8 |
| QSL9 | 400 | 2500-3000 | 1.5 |
3. User evaluation and market feedback
Through public opinion monitoring on e-commerce platforms and industry forums, the following trends were discovered:
1.reliability recognition: 82% of users believe that Doosan original engines perform stably under continuous operating conditions, among which the DL13P model won the "2024 Construction Machinery Golden Wrench Award".
2.Service response speed: Evaluation of the impact of dealer network coverage. Users in the western region are 15 percentage points less satisfied with the timeliness of parts supply than in the eastern region.
3.Technical training needs: 30% of new users reported that they were confused about the DPF regeneration operation process, and the number of clicks on related tutorial videos recently increased by 300%.
4. Suggestions on purchasing
1. For operations in plateau areas, it is recommended to choose a turbocharged and intercooled model, and pay attention to the special configuration of the engine air intake system.
2. Pay attention to the inventory status of local dealers to ensure adequate supply of commonly used filter elements and other consumable parts.
3. National IV models need to add urea solution regularly, and the cost of use is about 5-8 yuan/hour higher than that of National III models.
Current market data shows that the value retention rate of second-hand Doosan excavators equipped with DL series engines is 7-10 percentage points higher than the industry average, which confirms the market recognition of its power system. With the development of intelligence, it is expected that new models in 2024 will integrate more remote diagnostic functions. It is recommended that users continue to pay attention to official technology upgrade announcements.
