The invention relates to the technical field of engines, in particular to a multi-ported valve which comprises a valve seat and a valve plate. Multiple air inlet through holes and multiple air outletthrough holes are formed in the valve seat, and are formed at intervals; multiple gas guiding channels are arranged on the valve plate; the valve plate is abutted against the valve seat, so that eachgas guiding channel can be used for communicating one air inlet through hole with one adjacent air outlet through hole; and the valve plate and the valve seat can move relatively, so that each gas guiding channel can enable the communication of one air inlet through hole and one air outlet through hole adjacent to one side of the air inlet through hole to switch to the communication of one air inlet through hole and the other air outlet through hole adjacent to the other side of the air inlet through hole. According to the multi-ported valve, multiple ways of sample gases can be measured at the same time, so that the e
