Almost a decade and a half ago, General Motors, the largest auto manufacturer in the world launched another division in order to set new benchmark of vehicle machining, the Saturn. This is GM's response to the success of Japanese car imports to the United States. It was known for providing quality customer service and environmentally-conscious manufacturing processes. The vehicles were then developed to have remarkable image.
The success of Saturn wasn't just because of the image that the division has molded. It was largely due to the engineering that was incorporated within ever Saturn unit. The seats were designed to bring real comfort, air conditioning system for desirable temperature, body finish fine and smooth, well crafted as how they should be. The engines, transaxles, radiators, carburetors, and exhaust system brings the performance that a Saturn is worthy of.
Every part within every intricate system plays their role in order to completely unfold the capability that a Saturn can truly give. In the exhaust system alone, several indispensable auto parts are present, one of which is the exhaust manifold. A Saturn exhaust manifold is designed to collect the exhaust gases that the engine created within the operation. It is also the device that's intended to direct those gases to the exit ports for disposal. An exhaust manifold is typically comprised of exhaust pipe and seal, catalytic converter, muffler resonator, tail pipe, as well as heat shields. Its application depends of the engine that it's supposed to serve. An in-line type of engine requires a single manifold, while the V-type needs two.
There are several kinds of exhaust manifolds, all come in either cast or nodular iron. There's the exhaust manifold that's applicable only for normal 4-cylinder in-line engines. Another one is what called as two-into-one manifold, providing easier gas flow. In the modern auto machining, vehicles use the V-type engine. This one's need a manifold that faces the rear bank of cylinders, providing each with passage of their own that connects into a single passage. Also available is the exhaust manifold that can be identified by its long branches that are blended obliquely into the outlet, a design for reduction of back pressure. Then there's the high efficiency inners and outers tow-into-one system exhaust manifolds. The ones usually used for GT and sports cars.
