Cummins Unveils New Generation 15-Liter Off-Highway Engine - root - 04-13-2025
At the bauma construction machinery exhibition in Munich, Germany, Cummins unveiled its next-generation 15-liter off-highway engine. The X15 is a future-ready, multi-fuel heavy-duty engine platform capable of running on clean diesel, natural gas, renewable biofuels, or hydrogen—an ideal power solution for customers in construction, agriculture, and industrial sectors looking to improve energy efficiency, reduce emissions, and transition to cleaner energy.
Key Features of the New 15-Liter Off-Highway Engine:
- Optimized Design & Simpler Structure:
Compared to the previous generation, the engine offers higher power density, with outputs ranging from 400 to 700 hp (298 to 522 kW) and a peak torque of up to 3200 Nm, delivering high productivity while replacing larger-displacement engines.
- Broader Application Compatibility:
Over 20 power ratings are available, making it suitable for a wide range of applications.
- Compact & Lightweight:
Similar in size and weight to a 13-liter engine, it simplifies equipment integration.
- Versatile Emission Solutions:
Equipped with the Flex Module aftertreatment system, the engine meets EU Stage V and higher emission standards.
It operates without an EGR (Exhaust Gas Recirculation) system, reducing cooling system requirements and simplifying machine architecture.
In regions with less stringent regulations, it can meet emission requirements without aftertreatment or urea (DEF).
Advanced Components and Technologies:
- New HE550 Wastegate Turbocharger:
Made from upgraded materials for improved durability and reliability, with superior transient response in high-altitude environments.
- Dust-Proof Front-End Accessories:
Designed to prevent dust ingress and protect front-end components for reliable operation in harsh conditions.
- Steel Pistons:
Enhance engine durability and optimize combustion chamber and temperature control.
- Digital Capabilities:
Includes robust remote monitoring and diagnostics, OTA (Over-the-Air) software updates, and advanced telematics for high uptime even in remote locations.
- Optional Engine Braking Function:
Reduces axle brake wear and improves vehicle control.
Cost Efficiency & Environmental Benefits:
- Lower Fuel Consumption & Simplified Maintenance
The new engine provides up to 10% better fuel economy under comparable operating conditions than the previous generation.
- Longer Overhaul Intervals and lower total cost of ownership are further enhanced by digital remote services.
- Fuel Flexibility:
Fully compatible with next-generation biofuels including Hydrotreated Vegetable Oil (HVO) and B20 biodiesel blends, offering customers more energy transition options.
Cummins has launched a full range of B, L, and X Series multi-fuel engine platforms that are compatible with both current and future low-carbon and zero-carbon fuels, such as natural gas, clean diesel, and hydrogen, aiming to meet global future emission regulations and CO₂ targets.
