Cummins QSX15, ISX15, and X15 engines are known for their durability and strong performance in heavy-duty applications. These engines are built with advanced features and high-quality parts that ensure high power output, fuel efficiency, and compliance with emissions regulations.
Key engine components
Cylinder head: The cylinder heads for the Cummins QSX15 and ISX15 engines, such as part numbers 4962732 and 4900717, are critical for engine performance. They house the valve mechanism and support proper compression of air-fuel mixtures, boosting engine efficiency.
XPI fuel system: The XPI (eXtreme Pressure Injection) fuel system is a key feature in the QSX15, ISX15, and X15 engines. It enables multiple injection events per cycle, improving fuel economy, and engine performance, and reducing exhaust emissions.
Selective Catalytic Reduction (SCR) & Diesel Particulate Filter (DPF): These technologies reduce harmful emissions. SCR lowers nitrogen oxide (NOx) emissions, while DPF captures and removes particulate matter, enhancing environmental performance.
Camshaft & Gear: These parts control valve timing, ensuring smooth engine operation and contributing to long-term engine durability.
Crankshaft & Main Bearings: These components convert the up-and-down motion of the Pistons into rotational energy, enabling reliable mechanical operation.
Cylinder Block & Cylinder Liners: The cylinder block is the main structure of the engine, containing the cylinders, while cylinder liners reduce wear and tear, increasing the engine’s lifespan.
Electronic Control Module (ECM): The fully integrated ECM system manages all engine functions, from fuel delivery to exhaust after treatment, optimizing performance and reducing emissions.
Additional Features
Power Ratings and Torque: Cummins QSX15 engines offer up to 675 HP (503 kW) and torque ranging from 1650 to 2050 lb-ft (2237 to 2779 N·m). These engines provide a 60% increase in torque and 15% more power compared to other engines in their class, making them ideal for demanding applications like construction and mining.
Fuel Efficiency & Emissions: The engines use high-pressure common-rail injection technology and advanced aftertreatment systems to deliver exceptional fuel efficiency while meeting strict emissions standards.
These engines are designed to meet the needs of industries such as construction, agriculture, marine, and transportation.
