Exhaust Manifold Definition

It is connected with the engine cylinder block, and the exhaust gas of each cylinder is concentrated and introduced into the exhaust manifold, with a branched pipeline. The main requirements for it are to minimize the exhaust resistance and avoid mutual interference between the cylinders. When the exhaust is too concentrated, there will be mutual interference between the cylinders, that is, when a cylinder exhausts, it happens to encounter the undischarged exhaust gas from other cylinders. This will increase the resistance of the exhaust, thereby reducing the output power of the engine. The solution is to separate the exhaust of each cylinder as much as possible, one branch for each cylinder, or one branch for two cylinders, and make each branch as long as possible and form it independently to reduce the mutual influence of gases in different pipes.

Performance Requirements

Folded good high temperature oxidation resistance

Exhaust manifolds work in alternating high temperature cycles for a long time, and the anti-oxidation properties of materials at high temperatures directly affect the service life of exhaust manifolds.

Fold-stable microstructure

Because the phase change will cause the volume change, causing it to generate internal stress or deformation, affecting the performance and life of the product.

Folding coefficient of thermal expansion is small

A small thermal expansion coefficient is beneficial to reduce the thermal stress and thermal deformation of the exhaust manifold, and is beneficial to improve the performance and service life of the product.

Excellent high temperature strength when folded

The necessary strength requirements for the product to be used at high temperatures must be met.

Good process performance and low cost of folding

There are many types of heat-resistant and high-temperature resistant metal materials, but due to the complex shape of exhaust manifolds, the materials used to manufacture exhaust manifolds must have good manufacturability, and their cost must meet the needs of mass production in the automotive industry.
