Introduction

The Cummins 4955622 Engine Piston Kit is designed for use in heavy-duty truck engines. It plays a role in the operation of these vehicles by facilitating the conversion of fuel energy into mechanical work. This kit is integral to maintaining engine performance, efficiency, and durability under demanding conditions.

Basic Concepts of Engine Piston Kits

An engine piston kit typically includes pistons, piston rings, and wrist pins. These components work together within an internal combustion engine to ensure efficient operation. Pistons move up and down within the engine’s cylinders, driven by the combustion of fuel. This motion is transferred through connecting rods to the crankshaft, which converts it into rotational motion to drive the vehicle. Piston rings seal the combustion chamber, ensuring that pressure is maintained for efficient fuel combustion and minimizing oil consumption ¹.

Components of Cummins 4955622 Engine Piston Kit

Retaining Ring (3920691)

The retaining ring is a component within the Cummins 4955622 Engine Piston Kit. It serves the function of securing the piston pin within the piston assembly, ensuring that it remains in place during engine operation. This component is for maintaining the structural integrity of the piston and preventing any potential damage that could arise from a loose or displaced piston pin.

Piston Pin (3934047)

The piston pin, also known as the wrist pin, is another fundamental element of the Cummins 4955622 Engine Piston Kit. It connects the piston to the connecting rod, allowing for the smooth transfer of force from the combustion process to the crankshaft. The precision and durability of the piston pin are vital for the efficient and reliable operation of the engine.

Engine Piston (4934286)

The engine piston is the core component of the Cummins 4955622 Engine Piston Kit. It is responsible for converting the energy from the combustion of fuel into mechanical work. The piston moves up and down within the cylinder, driven by the pressure generated during the combustion process. Its design and material are optimized to withstand high temperatures and pressures, ensuring longevity and performance.

Piston Ring Kit (4955625)

The piston ring kit is an integral part of the Cummins 4955622 Engine Piston Kit. It consists of multiple piston rings that seal the combustion chamber, preventing the escape of gases and ensuring efficient compression. These rings also help in controlling oil consumption by scraping excess oil from the cylinder walls. The proper functioning of the piston ring kit is essential for maintaining engine efficiency and reducing emissions.
