Technical Excellence: Cummins 10.8L ISM11 Engine Specs
The XCEC ISM11E4-345 10.8L 345HP engine is designed with a focus on durability and efficiency. It utilizes advanced combustion technology to meet Euro IV emission standards while maintaining high power density.
Torque and Power Delivery
A standout feature is the ISM11E4-345 engine peak torque, which reaches 1669 N.m at 1200RPM. This low-end torque is critical for heavy-duty trucks starting under full load or navigating steep inclines. Compared to the lighter M11 series, the ISM11 series offers a more rigid block and improved cooling jackets for sustained high-load operations.
Advanced Fuel System and ECM Control
The ISM11E4-345 fuel system HPCR (High-Pressure Common Rail) performance ensures precise fuel atomization. Controlled by the sophisticated ECM 2220, the engine dynamically adjusts fuel timing based on load, which significantly reduces the Cummins ISM11E4-345 fuel consumption per hour in 8x4 truck configurations.
Unmatched Reliability in Harsh Conditions
The Cummins 345HP heavy-duty truck engine is built to survive. With a B10 design life reaching up to 2 million kilometers, it is the preferred choice for mining dump trucks and long-haul logistics. It features a robust cooling system and can operate in altitudes up to 5000 meters with automatic power compensation.
Superior Braking Performance
Safety is paramount. The ISM11 series is compatible with the Jacobs (engine brake) system, providing up to 326 HP of braking power. This reduces wear on your service brakes, making it ideal for steep downhill gradients often found in mining or mountainous construction sites.
Applications: From Shacman Trucks to Mining Equipment
The versatility of the DCEC ISM11 345HP diesel engine assembly makes it a universal choice for heavy machinery.
- Heavy-Duty Logistics: It is the genuine XCEC ISM11E4-345 replacement for Shacman trucks and Dongfeng tractors.
- Construction & Mining: Frequently used in mining dump trucks and Sany SRT33 rigid haulers due to its high dust tolerance.
- Specialized Vehicles: Ideal for concrete mixers and heavy-duty cranes where consistent PTO (Power Take-Off) performance is required.
