The utility model aims to design an intake manifold system, which can both meet the engine demands on air intake at different working conditions, and realize structure compact and light weight. The system divides the air inlet cavity into a left and a right two separate air inlet cavities, air inlet pipeline connecting to each side cylinder row is extended out on each air inlet cavity, the air inlet pipeline is divided into straight pipeline and bending pipeline, In addition, a power valve is arranged on the straight pipeline, a balance valve is arranged between the separated left and right air inlet cavities, the length of air flow route and the communication and isolation between the two air inlet cavities can be arranged through the open and close of the valves, thus different air supply to the engine is supplied at different working conditions, at the same time, the uniformity and stability of the left and the right cylinders exhausting and inhaling conditions are guaranteed. The intake manifold system can significantly improve the engine's dynamic characteristics, economy and emission performance,.
