Cummins®

The Cummins 41878 Compression Piston Ring is a component designed for use in heavy-duty truck engines. Its purpose is to enhance the efficiency and performance of the engine by ensuring optimal compression within the combustion chamber. This part is significant in the operation of heavy-duty trucks as it contributes to the overall reliability and efficiency of the engine, which is crucial for the demanding conditions under which these vehicles often operate.

Basic Concepts of Compression Piston Rings

Compression piston rings are components found in internal combustion engines. Their primary function is to create a seal between the piston and the cylinder wall. This seal is vital for maintaining compression within the combustion chamber during the engine’s power stroke. By ensuring that the air-fuel mixture remains compressed, these rings contribute to the engine’s efficiency and performance. They help in reducing the amount of blow-by, which is the leakage of combustion gases past the piston rings, thereby enhancing engine efficiency ¹.
