Advantages of QSF3.8 Industrial Engine
1. The overall modular design, the total number of parts is small, the failure rate is low, the structure is compact, and the maintenance is easy.
2. Using ultra-high pressure fuel pump, burning more fully under high fuel injection pressure, less energy loss, strong power, strong fuel adaptability, and lower emissions.
3. Mature intelligent electronic control technology improves the overall performance of the engine, and the engine specifications can be tailored according to the application needs, and the self-diagnosis and self-protection capabilities are stronger.
4. Adopt electronic control intelligent module to monitor the running status of the engine at any time, precisely control the fuel injection, so that the engine can also think.
