Introduction

The Cummins 2878507 Exhaust Valve is a critical component for commercial truck engines, facilitating the expulsion of exhaust gases from the combustion chamber. This valve is essential for maintaining engine efficiency and performance, ensuring smooth and effective truck operation.

Basic Concepts of Exhaust Valves

An exhaust valve within an internal combustion engine allows the release of exhaust gases post-combustion. It operates in tandem with the intake valve, which admits the air-fuel mixture. The exhaust valve opens at the end of the combustion cycle to expel spent gases and then closes to initiate the next cycle. This process is synchronized with the engine’s camshaft, which controls the valve’s timing ¹.
