Cummins ISME420 30 Heavy-Duty Diesel Engine
Engineered for Reliability and Performance in Demanding Applications
The Cummins ISME420 30 is a premium heavy-duty diesel engine, part of the globally respected ISM series. Manufactured by Xi'an Cummins Engine Co. (XCEC), this 10.8-liter powerplant delivers a robust 420 horsepower (306 kW) with exceptional low-end torque, making it an ideal and proven power source for a wide range of commercial vehicles and industrial equipment. Engineered for durability, fuel efficiency, and ease of maintenance, it offers a low total cost of ownership for fleet operators.
The ISME420 30 is engineered to be a versatile and reliable prime mover across multiple demanding sectors:
Heavy-Duty Trucks: A trusted power source for dump trucks, tractor units, and specialized vocational vehicles like cement mixer trucks and tankers.
Buses & Coaches: Provides reliable and efficient power for intercity coaches, tourist buses, and city buses.
Construction & Crane Machinery: Commonly specified for truck-mounted cranes and other heavy construction equipment requiring durable and responsive power.
Celect Electronic High-Pressure Common Rail Fuel System: This advanced system ensures extremely precise fuel injection, leading to superior combustion efficiency. The benefits include improved fuel economy, reduced emissions, significantly lower noise levels (up to 50% quieter operation), and excellent cold-start performance.
Full-Authority Intelligent Electronic Controls: The sophisticated Engine Control Module (ECM) optimizes performance in real-time and integrates seamlessly with vehicle systems. It enables over 100 control functions, including cruise control, road speed governing, and comprehensive diagnostics for proactive maintenance and fleet management.
Robust & Durable Architecture for Maximum Uptime: The engine is built for legendary longevity, with design features contributing to an average overhaul interval exceeding 1 million kilometers.
HX55 Turbocharger: Electronically controlled wastegate delivers ideal airflow across the entire operating range.
Articulated Pistons: Feature a forged steel crown and aluminum skirt for exceptional strength and reduced thermal stress.
Integrated Module Design: Utilizes approximately 30% fewer parts than comparable engines, which reduces potential failure points and simplifies maintenance.
Engineered for High Productivity: The combination of a high peak torque of 2010 N·m at a low 1200 rpm and responsive turbocharging ensures strong pulling power and acceleration, which is critical for loaded vehicles and challenging job sites.
