Exhaust manifold

The exhaust manifold is connected to the engine cylinder block, and collects the exhaust gas of each cylinder into the exhaust manifold with branched pipes. 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.
