The portfolio covers all key engine parts for the Dh300-7 ECU system, 포함하되 이에 국한되지는 않습니다.:
- 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: Dh300-7의 원래 공장 사양에 맞게 제작되었습니다., ±0.5% 이내의 치수 및 성능 공차, ECU 시스템과의 원활한 통합 보장.
- 향상된 환경 저항: 센서 및 배선 하네스에는 IP67 보호 등급이 있습니다.; ECU 제어 장치는 부식 방지 회로 기판 코팅을 채택합니다., 높은 진동에 대한 내성 (20g 이하), 극한의 기온 (-40℃ ~ +85℃), 먼지, 그리고 습도 (≤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) 표준, resisting electromagnetic interference from the Dh300-7’s hydraulic system and on-site construction equipment.
