Engine Computer Board For 366-8821 3668821 ECU CAT 320D Excavator Engine Parts

Specification

Description

This is an engine computer board with part number 366-8821, specially designed for 320D series excavators as core electronic control spare part of engine. Packed with standard specification carton, it features integrated die-cast housing to encapsulate built-in electronic chips and circuit modules. Precisely fitted with original wiring harness mounting positions of matching model, it centrally manages full electronic control of diesel engine including fuel injection logic, rotational speed adjustment, operating data collection and self-diagnosis of malfunctions. It can directly replace defective original ECU for aftermarket installation on 320D excavators.

Advantage

Fully consistent with original specification on dimension and connector layout, plug-and-play without any wiring modification to save maintenance time;
Adopts industrial-grade electronic components with rigorous encapsulation craft, excellent resistance against dust, moisture and vibration to adapt harsh construction site working conditions;
Finished bench simulation test before delivery with preloaded factory calibration data for target engine, no extra programming needed after installation to cut debugging cost;
Equipped with individual standard carton to avoid collision damage during storage and transportation, guarantee intact new condition.

Performance

Precise fuel injection control: Collect real-time data from coolant temperature, intake pressure, crankshaft speed sensors to dynamically adjust injection quantity and timing for better fuel combustion and lower fuel consumption;
Real-time malfunction monitoring: Continuously scan electronic sensor circuits and store fault codes automatically to accelerate troubleshooting for maintenance;
Wide temperature adaptability: Steady operation ranging from -30℃ to +75℃ without program crash or signal failure under extreme ambient temperature;
Adaptive power output: Automatically adjust engine power based on working load, enhance power reserve under heavy load and reduce output at no-load to balance machine performance and fuel efficiency.
