An exhaust manifold is a crucial component in an internal combustion engine. It collects exhaust gases from multiple cylinders and directs them into a single pipe, allowing for efficient expulsion of these gases from the engine. Typically made from cast iron or stainless steel, the manifold is designed to withstand high temperatures and pressures. Proper functioning of the exhaust manifold is essential for engine performance and emissions control. If it becomes cracked or damaged, it can lead to exhaust leaks, reduced engine efficiency, and increased emissions. Regular maintenance can help ensure the longevity of the manifold and the overall health of the engine.
