ISM420-30
Cummins
The Cummins ISM420-30 is a premium 10.8-liter heavy-duty diesel engine designed to deliver an outstanding balance of powerful performance, superior fuel economy, and legendary durability. As part of the globally proven ISM series, this 420-horsepower engine is engineered for the most demanding on-highway and vocational applications, providing operators with a reliable powertrain solution that maximizes productivity and minimizes total cost of ownership.
The ISM420-30 is engineered as the prime power source for heavy-duty vehicles where high horsepower, strong torque, and unwavering reliability are non-negotiable.
Heavy-Duty Trucks & Tractors: An excellent choice for high-performance 6x4 tractor units in long-haul freight and logistics, as well as heavy-duty rigid trucks for regional haulage.
Construction & Vocational Vehicles: Ideally suited for demanding applications such as concrete mixer trucks, heavy-duty dump trucks, and crane carriers, where its high torque output ensures consistent performance under load.
Specialized Haulage: Provides reliable power for high-GVW transport, including bulk carriers and specialized trailer configurations.
1. Advanced Electronic Control and High-Pressure Fuel System
The engine is governed by a sophisticated Full-Authority Electronic Control System. This integrates seamlessly with a state-of-the-art High-Pressure Common Rail (HPCR) fuel system. The system enables ultra-precise, multiple fuel injections per cycle, optimizing combustion for maximum power extraction from every drop of fuel. This results in exceptional fuel efficiency, lower emissions, and a smoother, quieter operation.
2. Robust Core Engine Design for Durability
Built for longevity, the ISM420-30 features a heavy-duty foundation. Its Modular Common-Rail Fuel System reduces parts count and potential leak points, enhancing reliability. Critical components like the forged steel crankshaft and articulated pistons with steel crowns are designed to withstand extreme cylinder pressures and provide an extended engine lifespan, even in severe operating conditions.
3. High-Efficiency Turbocharging & Air Management
Equipped with a highly efficient fixed geometry turbocharger and an advanced charge-air cooling system, the engine ensures optimal air intake for combustion. This design delivers excellent turbo response and a flat, high torque curve across a wide RPM range, providing strong pulling power and excellent drivability from low speeds.
