What engine does Sumitomo excavator use?
In the field of construction machinery, Sumitomo excavators are known for their high efficiency, durability and environmentally friendly performance. As the core component of the excavator, the engine directly affects the working efficiency and reliability of the equipment. This article will combine the hot topics on the Internet in the past 10 days, analyze the engine models, technical features and user feedback commonly used in Sumitomo excavators, and present them in structured data.
1. Mainstream engine models of Sumitomo excavators
Sumitomo excavators usually use engines imported from Japan or in cooperation with well-known brands. The following are engine models matching common models:
| Excavator model | Engine brand | Engine model | Displacement(L) | Power (kW) |
|---|---|---|---|---|
| SH210-5 | Isuzu | 4JG1 | 4.0 | 110 |
| SH350-3 | Yanmar | 4TNV98 | 3.3 | 180 |
| SH75-3 | Kubota | D1803 | 1.8 | 42 |
2. Engine technical characteristics
1.Environmental performance:Sumitomo excavator engines generally meet EU Stage V or China IV emission standards and use high-pressure common rail technology and EGR (exhaust gas recirculation) systems to reduce nitrogen oxide emissions.
2.Fuel economy:Through intelligent electronically controlled fuel injection and variable turbocharging technology, combustion efficiency is optimized and fuel consumption is reduced. For example, the fuel consumption rate of the Isuzu 4JG1 engine is 10% lower than similar products.
3.Durability:It adopts high-strength cast iron cylinder block and precision machining technology to extend its service life. User feedback shows that the Yanmar 4TNV98 engine can still operate stably for more than 8,000 hours under harsh working conditions.
3. User feedback and market hot spots
According to industry forums and social media discussions in the past 10 days, the following topics about Sumitomo excavator engines are relatively popular:
| topic | focus of discussion | Proportion of positive reviews |
|---|---|---|
| Fuel consumption performance | Most users recognized the low fuel consumption, but a few reported increased fuel consumption under plateau conditions. | 85% |
| maintenance cost | Original parts are more expensive but have a low failure rate | 78% |
| Noise control | Quiet design is better than domestic models | 90% |
4. Suggestions on purchasing
1.Matching conditions:Small machines (such as SH75-3) are suitable for urban construction, and Kubota engines are recommended; for large-scale mining conditions, it is recommended to choose SH350-3 with Yanmar engines.
2.After-sales service:Give priority to Sumitomo's official authorized dealers to ensure engine warranty and technical support.
3.Second-hand mobile phone identification:Check for abnormal noises when the engine is running and the color of the exhaust smoke, and avoid purchasing equipment that has been overhauled.
Conclusion
Sumitomo excavator engines have the core advantages of advanced technology, environmental protection and energy saving. Users can choose different models according to actual needs. In the future, with the popularization of hybrid technology, Sumitomo may further innovate in the engine field.
