- Engine-hydraulic coordinated control:
- E336E/E336F (C9.3): Optimize the match between the C9.3’s 250kW power output and the excavator’s 350bar high-pressure hydraulic system, ensuring stable boom/arm/bucket operation for bulk material loading and quarrying tasks;
- E349E (C9.3): Enhance power coordination with the excavator’s 400bar ultra-high-pressure hydraulic mode, eliminating hydraulic lag and preventing engine stalling during extreme heavy-load operations (e.g., rock blasting and heavy lifting).
- Precision fuel & emission management:
- All variants: Regulate fuel injection timing, pressure, and volume of the C9.3 engine to reduce fuel consumption by 3–5% under full load, while controlling the SCR (Selective Catalytic Reduction) and DOC (Diesel Oxidation Catalyst) systems to meet EU Stage IV / US EPA Tier 4 Final emission standards.
- E349E optimization: Prioritize fuel delivery stability for continuous ultra-heavy load operation to avoid power loss.
- Multi-sensor data processing: Collect real-time data from 24+ critical sensors (crankshaft position, hydraulic pressure, coolant temperature, exhaust gas temperature, particulate matter sensor) of the C9.3 engine in E336E/E349E/E336F, enabling full-cycle monitoring of engine/excavator status and early detection of anomalies (e.g., low oil pressure, EGR system faults, hydraulic leaks).
- Fault diagnosis & protective measures:
- E336E/E336F: Detect heavy-load faults (e.g., hydraulic pressure spikes, engine overheating) and trigger power limitation mode to protect the C9.3 engine and hydraulic pump;
- E349E: Identify ultra-heavy load faults (e.g., engine overload, hydraulic system pressure anomalies) and activate limp-home mode to prevent catastrophic component failure.
- All components store Diagnostic Trouble Codes (DTCs) compatible with CAT ET (Electronic Technician) diagnostic software for rapid troubleshooting.
