Функции | ХОВО 371 Двигатель (Национальный V) | ХОВО 380 Двигатель (Национальный VI) | Differential analysis and impact |
Смещение | ≈ 11.0X liters (common in HW19710) | ≈ 11.0X liters (например, MC11H.38-60) | The base displacement of the same platform is similar. The difference in power mainly stems from technical upgrades and adjustments. |
Номинальная мощность | ≈ 371 Лошадиные силы (273кВт) | ≈ 380 Лошадиные силы (279кВт) | The 380’s power has been slightly increased by about 9 Лошадиные силы. This means stronger climbing and overtaking capabilities, especially in heavy-load mountainous conditions. |
Максимальный крутящий момент | ≈ approximately 1800 Нм | ≈ Approximately 1900 Нм | The 380’s torque has been increased by about 100 Нм. It has stronger explosive power at low revs, making it easier to start and get out of trouble, and reducing the frequency of gear changes. |
Нормы выбросов | Национальный V | National VI B | Core generational differences! The 380 meets the highest current environmental requirements, has fewer traffic restrictions, and offers worry-free long-term operation. |
Aftertreatment system | СКР (Селективное каталитическое восстановление) | DOC+DPF+SCR integrated system | The 380 system is more complex and sophisticated. The DPF (diesel particulate filter) is key and requires regular regeneration, with extremely high requirements for fuel quality, urea, и обслуживание. |
Топливная система | High-pressure common rail | Upgraded high-pressure common rail (higher pressure, more precise control) | The 380 burns more completely, has lower fuel consumption potential, and offers more refined power response. |
Technical highlights | Mature and stable | Intelligent electronic control, efficient turbocharging, low-friction technology | The 380 has been further optimized in terms of combustion efficiency, thermal management, and friction loss, offering superior theoretical reliability and economy. |
Maintenance complexity | Relatively simple | Significantly improved | The 380 aftertreatment system (especially the DPF) requires professional diagnostic equipment and technology, placing higher demands on repair station capabilities. |
Parts cost | Relatively low (abundant market inventory) | Relatively high (new system, new components) | The replacement costs for the 380’s sensors, aftertreatment components, и т. д.. are higher. |
Compatible models | National V-compliant HOWO heavy-duty trucks (например, older A7/T7 models) | National VI stage HOWO full-series heavy-duty trucks (например, TH7/TX series) | The 371 is gradually being phased out, и 380 is the current and future mainstay. New vehicles must be purchased with the National VI platform. |
