The QSM11/M11 engine is an inline six-cylinder diesel engine.


This means that it has six cylinders arranged in a straight line along the engine block. This configuration offers several advantages, including smooth operation, compact design, and excellent balance. The inline arrangement of cylinders allows for efficient combustion and power delivery, making it a preferred choice for a wide range of applications.

Displacement:
The displacement of the QSM11/M11 engine is approximately 10.8 liters. Displacement refers to the total volume of air that the engine can intake during one complete engine cycle. A larger displacement generally results in higher power output and torque, which is advantageous for heavy-duty applications such as trucks, buses, and industrial equipment.

Power and Torque:
The QSM11/M11 engine is available in a range of power ratings, typically from 280 to 400 horsepower (hp). Torque output varies accordingly, with a peak torque rating of around 1450 to 1650 lb-ft (pound-feet). This ample power and torque make it suitable for various applications, including transportation, construction, and marine.

Fuel System:
One of the notable features of the QSM11/M11 engine is its advanced fuel system. It utilizes a high-pressure common rail fuel injection system, which precisely delivers fuel to each cylinder at the right moment for optimal combustion. This technology improves fuel efficiency, reduces emissions, and enhances overall engine performance.

Turbocharging:
To further enhance power and efficiency, the QSM11/M11 engine is equipped with a turbocharger. Turbocharging compresses incoming air, allowing more oxygen to be available for combustion. This results in improved power output and responsiveness, especially at lower engine speeds.

Cooling System:
Efficient cooling is crucial for engine longevity and performance.


The QSM11/M11 engine employs a liquid cooling system, which circulates coolant through the engine block to dissipate heat. This ensures that the engine operates within its optimal temperature range, preventing overheating and potential damage.

Emissions Control:
Modern diesel engines must meet stringent emissions standards. The QSM11/M11 engine incorporates advanced emissions control technologies, such as exhaust gas recirculation (EGR) and selective catalytic reduction (SCR), to reduce harmful emissions, including nitrogen oxides (NOx).

Applications:
The versatility of the QSM11/M11 engine allows it to be used in a wide range of applications. It is commonly found in heavy-duty trucks, buses, construction equipment, and marine vessels. Its reliability and durability make it a preferred choice for industries that demand consistent performance under challenging conditions.

Maintenance and Service:
Proper maintenance is essential to ensure the longevity and reliability of the QSM11/M11 engine. Regular oil changes, filter replacements, and inspections are crucial to keep the engine running smoothly. Cummins provides comprehensive service and support to assist customers in maintaining their engines.
