Wholesale Cummins 6BT Diesel Engine Cylinder Block
The cylinder block is the main body of the engine, it will be each cylinder and crankcase into one, is the installation of the piston, solar collector crankshaft, and other parts and accessories of the support skeleton.
The diesel engine cylinder block for Cummins is designed to withstand high levels of stress and pressure, as well as exposure to high temperatures and corrosive substances. It is also designed to provide a precise fit for the engine’s pistons, connecting rods, and other internal components, ensuring optimal performance and longevity.
Optimize the Performance:
The cylinder block in a diesel engine features various ports and passages that are designed to optimize the flow of air, fuel, and exhaust gases, thereby improving the engine’s performance and efficiency. These ports and passages are carefully designed to ensure that the air and fuel mixture is delivered to the cylinders in the most efficient manner possible, while also allowing for the efficient removal of exhaust gases. The cylinder block includes many intake ports that allow air to enter the engine, fuel injection ports that deliver fuel to the cylinders, and exhaust ports that allow for the efficient removal of exhaust gases. The size, shape, and location of these ports and passages are carefully designed to optimize the engine’s performance and efficiency, while also minimizing emissions and maximizing fuel economy.
Convenient:
The cylinder block in a diesel engine provides a precise mounting location for the engine’s pistons, connecting rods, and other internal components, ensuring optimal performance and longevity. The precise fit of these components is critical to the engine’s performance, as any misalignment or deviation from the correct specifications can result in reduced power output, increased wear and tear, and decreased engine life. To ensure a precise fit, the cylinder block is carefully machined to exacting tolerances, with each mounting location and bore carefully measured and inspected to ensure that it meets the engine manufacturer’s specifications. The block also features various alignment pins, dowels, and other components that help ensure that the pistons, connecting rods, and other internal components are properly aligned and secured in place.

The role of the cylinder block
About the role of the cylinder block, the cylinder block is the main body of the engine, it will be each cylinder and crankcase into one, is the installation of the piston, solar collector crankshaft, and other parts and accessories of the support skeleton.
Cylinder body working conditions are very harsh. It has to withstand the rapid changes in pressure and temperature during the combustion process and the strong friction of the piston movement. Therefore, it should have the following properties.
Cylinder block performance
1. Have sufficient strength and stiffness, small deformation, to ensure the correct position of the moving parts, normal operation, low vibration, and noise.
2. Have good cooling performance, in the cylinder barrel around the cooling water jacket, to let the cooling water take away the heat.
3. Wear-resistant to ensure that the cylinder block has a sufficient service life.
The upper part of the cylinder block is the cylinder barrel side by side, at present more set with cylinder liner. The lower part of the cylinder block is the crankcase, used to install the crankshaft, its external can also be installed generator, extension cord engine bracket, and other accessories. Most of the cylinder blocks with cast iron or aluminum alloy casting, aluminum alloy cylinder cost is higher, but lightweight, good cooling performance, more and more widely used.
The composition of the cylinder block
The block is the skeleton of the engine, the engine mechanism, and the installation of the system base, its internal and external installation of all the main parts of the engine and accessories, bearing a variety of loads. Therefore, the body must have sufficient strength and rigidity. The body group is mainly composed of the cylinder block, crankcase, cylinder head, cylinder gasket, and other parts.
Why cylinder block and cylinder head will produce cracks?
Cylinder block and cylinder head easy-to-crack parts are often related to their structure, different forms of engine cracking parts each have certain regularity. Cylinder block cracks appear for the following reasons.
1. Some improved engines are enhanced models, the power of the original engine significantly increased, and the speed also increased. In high speed, inertia force, stress, easy to crack.
2. Cylinder block structure is complex, uneven wall thickness everywhere, in some weak parts, low stiffness, prone to cracking.
3. High speed, crankshaft vibration, increasing the load of the cylinder block, in the weak parts prone to cracking.
4. Processed parts and unprocessed parts, the wall thickness of different parts of the transition will produce stress concentration. When the stress concentration and the casting of residual internal stress are superimposed, easy to produce cracks.
5. Improper use, such as the engine for a long time in overload conditions, the cylinder block stress is too large, and the cylinder block is also prone to cracking.
6. In the engine in a high-temperature state suddenly add cold water, resulting in excessive thermal stress, and the cylinder block is prone to deformation or cracking.
7. The water jacket in the scale is too thick, reducing the coolant through the area, at the same time, due to the poor heat transfer of scale, reducing the engine cooling performance, especially between the cylinder, valve seat between the waterway is blocked, seriously affect its heat transfer, so that the local working temperature increases, thermal stress is too large, prone to cracking.
8. In winter, after parking without the timely release of water and freezing cracking occurs. Some people also start first, after adding coolant, resulting in excessive local thermal stress, or in the cold winter, the sudden addition of high-temperature hot water and cracking.
