An Upper Exhaust Manifold is responsible for directing exhaust gases from the engine cylinders to the manifolds connecting to the turbocharger. As exhaust gases pass through the manifold, they enter the turbocharger's turbine, driving its rotation and causing the compressor to draw in and compress air, which is then delivered to the engine's intake manifold. This process increases the volume of air entering the engine, allowing for more efficient combustion and boosting engine power and efficiency.Attributes:• Resists high temperatures and thermal stress.• Provides a centralized point for air line connections.• Helps prevent leaks and pressure drops in the air distribution system.Applications: An Upper Exhaust Manifold is connected to the left-hand side of engine block cylinders to the manifolds which are connected turbocharger, serving as the conduit for directing exhaust gases to the turbocharger for the turbocharging process.
