The portfolio covers all key engine parts for the Dh300-7 ECU system, y compris, mais sans s'y limiter:
- ECU Control Unit (Main Board): The core computing and control component of the ECU system, responsible for regulating engine operation parameters.
- ECU System Sensors: Crankshaft position sensor, camshaft position sensor, coolant temperature sensor, intake air pressure sensor, oil pressure sensor, and exhaust gas temperature sensor (all calibrated for Dh300-7).
- ECU Wiring Harness & Connectors: High-temperature and anti-abrasion wiring harnesses with waterproof connectors, matching the original Dh300-7 ECU interface layout.
- Fuel Injection Control Module: Auxiliary component for the ECU system, coordinating with the main ECU to control fuel injection precision.
- ECU Power Relay & Fuses: Specialized power protection components for the Dh300-7 ECU system, preventing damage from voltage fluctuations.
- ECU Programming & Calibration Tools: Dedicated tools for parameter matching and fault diagnosis of the Dh300-7 ECU system.
A3: All parts are engineered for long-term stable operation in harsh construction environments, with key reliability features:
- Original-Grade Precision: Fabriqué pour correspondre aux spécifications d'usine d'origine du Dh300-7, avec des tolérances dimensionnelles et de performance de ±0,5 %, assurant une intégration transparente avec le système ECU.
- Résistance environnementale améliorée: Les capteurs et faisceaux de câbles ont un indice de protection IP67; Les unités de commande ECU adoptent un revêtement de circuit imprimé anticorrosion, résistant aux fortes vibrations (≤20g), températures extrêmes (-40℃ ~ +85℃), poussière, et l'humidité (≤95% RH).
- Consistent Performance: All parts undergo a 500-hour accelerated aging test, with performance attenuation ≤3% during service life, avoiding sudden ECU system failures.
- Anti-Interference Design: ECU-related electrical parts comply with EMC (Electromagnetic Compatibility) normes, resisting electromagnetic interference from the Dh300-7’s hydraulic system and on-site construction equipment.
