Intake Manifold
Enabling Smooth Flow of Exhaust Gases
Jeep is well-known for its toughness and extreme reliability on off-road terrains and extreme adventures. No wonder why off-road travelers have chosen the SUV giant to be their ideal companion. Jeep vehicles like the Hurricane, Cherokee, and Wrangler are crisply engineered and powerfully designed to conquer all kinds of terrain conditions. To live up to its billing, Jeep depend on efficient performance parts, which enables the car maker to produce powerful climbers.
An important performance part of Jeep is the exhaust manifold. Made of cast iron or tubular steel, the Jeep Exhaust Manifold is attached at the exhaust side of the cylinder head. An exhaust manifold gasket is used at the connection to ensure a good seal. Jeep engines with in-line cylinders normally have one exhaust manifold. Engines with V-type cylinders, like the V6 and V8, contain two separate exhaust manifolds, one mounted to each cylinder head.
The Jeep Exhaust Manifold, acting as the exhaust pipe's connection point, brings the exhaust gases leaving the cylinder head to the exhaust system. The Jeep Exhaust Manifold is designed with smooth curves so that the flow of the exhaust gases would greatly improve. Made from 16-gauge aluminum steel tubing, the Jeep Exhaust Manifold is also spindle-bent to remove harmful back pressure. There may be two exhaust pipe connections depending on engine configuration and the number of exhaust manifolds. The Jeep Exhaust Manifold may also serve as a mounting location for the air injection system or an oxygen sensor. In addition, some exhaust manifolds have a heat riser valve, controlled by a temperature-sensitive spring. This valve's role is to help divert hot exhaust gas through a separate passage in the intake manifold to aid in better engine warm-up.
Although not commonly replaced with other exhaust system parts, Jeep's exhaust manifolds need to be checked periodically to ensure they are secured, free from cracks, and the exhaust pipe mounts tightly held. A “ticking” noise during acceleration or the sound or smell of leaking exhaust could indicate a leak at the manifold or its connections. Another leak symptom is a failed emissions test. It is important to have problem checked immediately, since a leak lets exhaust gas out. It also allows oxygen to enter the exhaust stream, which can be detected during an emissions test.
It is important for all the Jeep's performance parts, including its exhaust manifold, to work efficiently. Keeping punishing terrains at bay depends on these parts' tiptop condition.
