Cummins®

The Cummins 5374639 Exhaust Manifold is a component designed for use in commercial trucks. It plays a role in the engine system by directing exhaust gases away from the engine cylinders. This part is significant for maintaining the efficiency and performance of the truck’s engine, ensuring that exhaust gases are expelled effectively and contributing to the overall operation of the vehicle.

Basic Concepts of Exhaust Manifolds

An exhaust manifold is a part of the engine system that collects exhaust gases from the engine’s cylinders and directs them into the exhaust system. It operates by channeling the high-temperature, high-pressure gases produced during the combustion process away from the engine ¹. Common materials used in manufacturing exhaust manifolds include cast iron, stainless steel, and in some cases, ceramic-coated steel. These materials are chosen for their ability to withstand high temperatures and resist corrosion, ensuring durability and longevity in demanding environments ².
