Z14NS6B560
Cummins
The Cummins Z14NS6B560, part of the renowned Z14 series from Dongfeng Cummins (DCEC), is a state-of-the-art heavy-duty diesel engine engineered to deliver exceptional power, superior reliability, and outstanding fuel efficiency for the most demanding on-highway and vocational applications. With a commanding 418 kW (560 HP) and massive low-speed torque, this 13.5L inline-6 cylinder powerhouse is built to maximize productivity and minimize total cost of ownership for heavy trucks and specialized vehicles.
This engine is designed as the prime mover for a broad spectrum of heavy-duty and specialized equipment:
Heavy-Duty Trucks: The primary application for on-highway transportation, providing the power needed for long-haul logistics, heavy haulage, and dump trucks.
Vocational & Construction Vehicles: An ideal power source for specialized chassis used in concrete mixer trucks, crane trucks, and other demanding construction applications.
Buses: Suitable for powering large coaches and buses requiring robust and reliable performance.
Specialized Equipment: Can also be configured for use in engineering machinery, mining equipment, and as a prime power source for generator sets.
Advanced High-Pressure XPI Fuel System: The engine features an XPI (Extreme Pressure Injection) fuel system. This technology enables extremely high injection pressure for superior fuel atomization, resulting in exceptionally clean and efficient combustion, which contributes to lower emissions and improved fuel economy.
Optimized Combustion Architecture for Power and Efficiency: The design incorporates several key features for optimal performance:
Extended Stroke Design: The 145mm stroke allows for more complete expansion of combustion gases, directly increasing effective efficiency and output for better overall economy.
Four-Valve Cylinder Head & Central Injector: The advanced four-valve-per-cylinder structure improves airflow for greater horsepower and increased low-speed torque. The centrally located injector paired with a symmetrical combustion chamber creates a more homogeneous air-fuel mixture, ensuring cleaner and more thorough burning.
Exceptional Durability and Reliability: Engineered for a long service life, key components like the articulated pistons are built to withstand extreme mechanical and thermal loads, providing strength comparable to larger displacement heavy engines. This robust construction is proven, with data showing over 30% of these engines achieving 800,000 kilometers without a major overhaul.
Superior Cold-Start Performance: Equipped with an air suction electric preheater and a high-power starter (7.8 kW), the engine delivers reliable starting in extreme cold weather, validated to operate in temperatures as low as -36°C.
