Cummins ISM11E5-345 Diesel Engine – 10.8L 345HP Euro V Heavy-Duty Power Solution
The Cummins ISM11E5-345 diesel engine is a Euro V compliant 10.8L heavy-duty power unit developed by Xi’an Cummins (XCEC) for modern commercial vehicles. With a rated output of 345HP and strong low-speed torque, this engine is widely used in heavy-duty trucks, mining dump trucks, and long-distance logistics fleets.
Compared with earlier ISM11E4 models, the ISM11E5-345 integrates an advanced SCR (Selective Catalytic Reduction) system, enabling reduced emissions and improved fuel efficiency. As a professional supplier, HekoPower provides genuine Cummins ISM11E5-345 engine assemblies with strict quality inspection, competitive pricing, and global delivery support.

Technical Superiority
Torque Curve and Performance Review
The ISM11E5-345 engine torque curve at 1200 RPM allows for exceptional "lugging" capability. This means drivers can maintain higher gears on inclines, directly reducing Cummins ISM11E5-345 fuel consumption per hour. Compared to the ISM11E5-385, the 345HP variant offers a more balanced fuel-to-power ratio for 20-ton to 40-ton vehicle configurations.
SCR System and AdBlue Consumption
A critical part of the ISM11E5-345 emission standard Euro V compliance is the Selective Catalytic Reduction (SCR) system. Users often ask about the Cummins ISM11E5-345 AdBlue consumption per 100km; typically, it ranges from 5% to 7% of fuel consumption. This system, managed by the ECM control system, ensures the engine meets strict NOx limits without sacrificing raw torque.
Applications: From Sany SRT33 to Dongfeng Trucks
What trucks use the Cummins ISM11E5-345 engine? Its versatility is unmatched:
- Mining: The standard ISM11E5-345 in Sany SRT33 mining trucks and other off-highway power packs.
- Logistics: Primary XCEC ISM11E5-345 engine for Dongfeng trucks and Shacman X3000 series.
- Marine & Power: Also adaptable as a Cummins ISM11 345HP marine propulsion engine or for high-output generator sets.
