Q1: 제품 식별번호와 적용 범위는 무엇입니까??
A1: 이 제품은 489-7907 (alternate model: 4897907) ECU Engine Control Unit, a dedicated core control part exclusively engineered for Caterpillar E320GC and E336GC excavators equipped with the C7.1 diesel engine. It serves as the “central computing hub” of the C7.1 engine system, ensuring precise regulation of engine performance and seamless integration with the electronic architecture of E320GC/E336GC excavators.
2분기: 어떤 핵심 기능을 수행합니까? 489-7907 ECU perform for the C7.1 engine in E320GC/E336GC excavators?
A2: 그만큼 489-7907 ECU is tailored to optimize the operation of the C7.1 engine in E320GC/E336GC excavators, with the following core functions:
- Precision fuel injection control: Regulates the C7.1 engine’s fuel injection timing, 압력, and volume per cylinder, maximizing power output (matching the original rated power of C7.1 for E320GC/E336GC) while reducing fuel consumption by 4-6% 일반적인 작업 조건에서.
- Real-time parameter monitoring: Collects data from 20+ 주요 센서 (크랭크샤프트 위치, 냉각수 온도, 유압, intake air flow, exhaust temperature) of the C7.1 engine, providing full-cycle monitoring of engine operating status.
- 고장진단 & 보호 조치: Automatically detects abnormal conditions (예를 들어, 과열, 낮은 오일 압력, fuel system malfunctions) of the C7.1 engine, 진단 문제 코드 저장 (DTC), 보호 모드를 트리거합니다. (예를 들어, power reduction) to prevent irreversible engine damage.
- 부하 적응 조정: Adjusts the C7.1 engine’s idle speed, acceleration, and combustion efficiency in real time based on the E320GC/E336GC excavator’s working load (가벼움/중간/무거움), ensuring stable operation during digging, 리프팅, 그리고 여행.
- 시스템 상호 운용성: Establishes seamless data communication with the E320GC/E336GC’s hydraulic control unit, instrument panel, and telematics system, enabling real-time status display and remote monitoring of the C7.1 engine.
