This article will analyze the engine types, technical features and market feedback of Hitachi excavators, and provide you with structured data based on hot topics in the past 10 days.
1. Common engine models and parameters of Hitachi excavators
| Engine model | type | Displacement(L) | Power (kW/HP) | Emission standards |
|---|---|---|---|---|
| Isuzu 4HK1 | diesel turbo | 5.2 | 129/173 | National III/European III |
| Hitachi HINO J05E | High voltage common rail | 5.1 | 187/250 | National IV/European IV |
| Isuzu 6WG1 | Electronically controlled direct injection | 15.7 | 287/385 | National V/European V |
2. Analysis of technical characteristics
1.Efficient fuel system: Hitachi excavators mostly use high-pressure common rail technology, which has high fuel injection accuracy, more complete combustion, and reduced fuel consumption by about 8%-12%.
2.Environmentally friendly design: The latest model complies with National IV/Euro IV standards and above, and is equipped with DPF (diesel particulate trap) and SCR (selective catalytic reduction) systems.
3.Intelligent control: Monitor the engine status in real time through the ECU (electronic control unit), automatically adjust the power output, and extend the service life.
