ISDe
Cummins
Product Overview
The Cummins ISDe series is a renowned family of mid-range diesel engines, spanning from 4.5L to 6.7L displacements. Engineered for reliability and performance, it delivers an optimal balance of fuel efficiency, robust power, and low total cost of ownership for a wide spectrum of on-highway applications.
Core Applications & Equipment
The ISDe engine is a versatile and dependable power source for various equipment, including:
Trucks: Medium-duty distribution trucks, haulers, and dump trucks.
Buses & Coaches: City transit buses, intercity coaches, and school buses.
Special Vehicles: Mobile cranes, utility vehicles, and other vocational equipment.
Core Technologies & Innovations
The ISDe's performance is built on a foundation of advanced engineering:
Full-Authority Electronic Controls & Bosch HPCR System: A high-performance Electronic Control Module (ECM) manages the Bosch High-Pressure Common Rail (HPCR) fuel system. This ensures ultra-precise fuel injection timing and quantity, leading to superior combustion, excellent throttle response, and significant noise reduction.
Advanced Emissions Technology: To meet stringent global standards like Euro V and China National V, the ISDe series utilizes a Selective Catalytic Reduction (SCR) aftertreatment system. This technology efficiently reduces nitrogen oxide (NOx) emissions without compromising engine power or fuel economy.
Robust Engine Architecture: Features like a high-strength cylinder block with integrated fluid passages, a 24-valve cylinder head for optimal airflow, and heavy-duty roller followers contribute to durability, quiet operation, and extended service life.
Turbocharged Performance: Equipped with efficient turbochargers (such as the wastegated HX40) to deliver strong low-end torque and exceptional power output across the entire operating range.
