Shop Cummins CCEC QSM11 Diesel Engine Cylinder Block 4060393 | Tonkee®

The Cummins CCEC QSM11 Diesel Engine Cylinder Block is crafted with precision and durability in mind.

It is typically made from high-quality cast iron, known for its excellent mechanical properties and resistance to wear and tear. This robust construction ensures the cylinder block can withstand the extreme pressures and temperatures generated within the engine during combustion.

Cylinder Arrangement:
The QSM11 engine is an inline six-cylinder engine, which means that this cylinder block houses six individual cylinders aligned in a single row. This arrangement optimizes engine balance and efficiency, ensuring smooth operation and even power distribution.

Bore and Stroke:
The bore and stroke dimensions of the cylinder block are crucial for determining the engine's displacement and performance characteristics. While specific measurements may vary depending on the engine's application and configuration, the QSM11 series typically features a bore of approximately 4.88 inches (124 mm) and a stroke of around 5.71 inches (145 mm). These dimensions contribute to the engine's overall displacement and power output.

Cooling System:
Efficient engine cooling is essential to prevent overheating and ensure optimal performance. The cylinder block includes passages for coolant circulation, allowing it to maintain the engine's operating temperature within a safe range. This is particularly important in heavy-duty applications where engines are subjected to high loads and extended operation.

Crankshaft and Connecting Rods:
The cylinder block provides the mounting points for the crankshaft and connecting rods.

The crankshaft is responsible for converting the reciprocating motion of the pistons into rotational motion, which drives various vehicle components. Connecting rods link the pistons to the crankshaft, transferring the force generated during combustion. The precise alignment and attachment of these components within the cylinder block are critical to the engine's overall reliability and performance.

Piston Assembly:
Each cylinder within the block houses a piston that moves up and down within the cylinder bore during the engine's operation. The piston assembly includes components such as piston rings and wrist pins, which are essential for maintaining compression and allowing the piston to move smoothly within the cylinder. Proper clearance and sealing between the pistons and cylinder walls are vital for engine efficiency and longevity.

Compatibility and Applications:
The Cummins CCEC QSM11 Diesel Engine Cylinder Block, part number 4060393, is designed specifically for use with the QSM11 series of Cummins diesel engines. These engines are commonly utilized in a wide range of applications, including construction equipment, marine vessels, power generators, and heavy-duty trucks. Their versatility and reliability make them a popular choice in industries that demand robust and efficient diesel power.
