Every part of your truck is important. Each part is carefully assembled and placed in its specific location to attain its ideal and desired function. One of the most important parts of a truck engine is the exhaust system or the system that is responsible for releasing heat and pressure inside the truck engine to prevent overheating and to keep the truck running. An exhaust system has different parts such as the muffler, exhaust gas collector, turbo charger, and exhaust manifold, among others. Each of these parts plays an important function that without the other or if one of these parts is missing, your truck would malfunction and may lead to further truck engine damage.
How Does an Exhaust Manifold Function?
One of the most important parts of the exhaust system of a truck is the exhaust manifold. A normal exhaust system comprises of tubes and cylinders that help in allowing easier and free exhaust gas passage from the engine to the air. A functioning exhaust system prevents overheating and optimized engine condition. To facilitate this free passage of gas along the exhaust system, a well-maintained exhaust manifold is required.
An exhaust manifold is a network of tubes that guides the exhaust gases from the different exhaust ports of the engine toward the catalytic converter and the muffler that minimizes the sound produced by the truck engine toward the external environment. The cylinders in the exhaust manifold create pressure as exhaust gas is released by the engine. This back pressure tends to build up and affects other cylinders that use the manifold. The main function of the exhaust manifold, aside from routing the exhaust gas, is to release this back pressure and allow the engine to work properly. The design and the number of exhaust manifold would depend on the heads of cylinder to where the exhaust manifolds are attached.
Types of Materials Used for Exhaust Manifold
Exhaust manifolds are usually made of the following materials:
- Stainless steel
- Cast iron
- Ceramic. An exhaust manifold made of ceramic could be light weight but it could crack with too much heat and pressure
Warning Signs of a Malfunctioning Exhaust Manifold
To ensure optimum truck engine performance and to keep your engine running for the longest time, you need to periodically have your engine checked by a truck engine expert for proper tuning and to check the essential parts of your truck. Also, you need to be sensitive about unusual sounds such as tapping, clicking, or popping sound in the engine area and exhaust system. Unusual sounds in the exhaust manifold usually mean that something is wrong with your engine and it needs to be checked right away to avoid further damage and bigger repair costs. As part of your truck maintenance, you need to ensure that the materials and parts used on your truck is top of the line and made by reputable spare parts maker so as not to jeopardize its quality and your truck's engine performance.
