Cummins Engine Part Intake Valve Kit 3804867 for Cummins QST30 Engine

Engine Exhaust Manifold:

1. The engine exhaust manifold is connected to the engine cylinder block. It collects the exhaust of each cylinder and leads it to the exhaust manifold. It has different pipelines. The main requirement for it is to minimize the exhaust resistance. , and avoid mutual interference between cylinders;

2. When the exhaust is too concentrated, there will be mutual interference between the cylinders, that is, when a cylinder is exhausted, it happens to encounter the undischarged exhaust gas from other cylinders, which will increase the resistance of the exhaust. thereby reducing the output power of the engine;

3. 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, in order to reduce the exhaust resistance.
