The piston set 4955348 is designed for use in the Cummins ISM11, QSM11, and M11 engines.
It is manufactured using high-quality materials, typically aluminum alloy, which offers an ideal balance of strength and lightweight characteristics. This alloy ensures durability and heat resistance, essential for an engine's piston that experiences extreme temperatures and pressures during operation.
Piston Diameter and Compression Ratio:
The piston diameter is a critical specification as it determines the engine's displacement and compression ratio. The exact diameter can vary depending on the engine's specific configuration and application. A larger piston diameter typically results in higher engine displacement and potentially a higher compression ratio, which can affect engine performance and efficiency.
Piston Ring Grooves:
Piston rings are essential for maintaining proper compression and preventing oil from entering the combustion chamber. The piston set 4955348 is designed with precision-machined grooves to accommodate these piston rings. The number and dimensions of these grooves are engineered to meet the engine's specific requirements, ensuring proper sealing and combustion efficiency.
Cooling Features:
Diesel engines generate a significant amount of heat during operation. To prevent overheating, pistons often incorporate cooling features like oil galleries or cooling channels. These features help dissipate heat and maintain optimal operating temperatures. The design of the piston set 4955348 may include such cooling features to ensure engine longevity and reliability.
Skirt Design:
The piston's skirt is the lower portion that comes into contact with the cylinder wall.
It must be precisely designed to minimize friction, reduce wear, and ensure proper lubrication. The skirt design of the 4955348 piston set is engineered for optimal performance within the Cummins ISM11, QSM11, and M11 engines.
Pin and Connecting Rod Compatibility:
Pistons are connected to the engine's crankshaft through a connecting rod and wrist pin. The 4955348 piston set is designed to be compatible with the engine's specific connecting rod and wrist pin, ensuring a secure and reliable connection that can withstand the engine's power and vibrations.
Ring Types and Arrangement:
The piston set 4955348 may include different types of piston rings, such as compression rings and oil control rings, arranged in specific configurations to maximize sealing, minimize oil consumption, and maintain combustion efficiency. The precise arrangement of these rings is crucial for engine performance and emissions control.
Piston Crown Shape:
The piston crown is the top surface of the piston that is exposed to the heat and pressure of combustion. Its shape and design play a significant role in optimizing the combustion process and controlling emissions. The piston set 4955348 is engineered with a specific crown shape to meet emissions regulations and achieve efficient combustion.
OEM Standards:
It's important to note that the piston set 4955348 is designed to meet or exceed the original equipment manufacturer (OEM) standards set by Cummins. This ensures that it is a reliable and compatible replacement part for these engines, meeting the same performance and quality standards as the original pistons.
