C9.3 エンジン用ホットセール E336e E349e E336f 掘削機部品

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 (例えば, rock blasting and heavy lifting).
Precision fuel & emission management:
- All variants: Regulate fuel injection timing, プレッシャー, 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 / 米国EPAレベル 4 Final emission standards.
- E349E optimization: Prioritize fuel delivery stability for continuous ultra-heavy load operation to avoid power loss.
マルチセンサーデータ処理: Collect real-time data from 24+ critical sensors (クランクシャフト位置, 油圧, 冷却水温度, 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 (例えば, 油圧が低い, EGR system faults, 油圧漏れ).
故障診断 & 保護措置:
- E336E/E336F: Detect heavy-load faults (例えば, hydraulic pressure spikes, エンジンのオーバーヒート) and trigger power limitation mode to protect the C9.3 engine and hydraulic pump;
- E349E: Identify ultra-heavy load faults (例えば, engine overload, hydraulic system pressure anomalies) and activate limp-home mode to prevent catastrophic component failure.
- All components store Diagnostic Trouble Codes (DTC) compatible with CAT ET (Electronic Technician) diagnostic software for rapid troubleshooting.
