Reforming system and reforming disorder diagnostic method using a pressure sensor

摘要

A reforming system may include a motor; an intake pipe connected to the engine; an exhaust pipe connected to the engine; a reformer provided at an exhaust gas recirculation (EGR) pipe branching from the exhaust pipe and mixing exhaust gas with fuel; a front-end pressure sensor provided in the EGR passage of the front end portion of the reformer and measuring a pressure of the exhaust gas of the front end portion of the reformer; a back pressure sensor provided in the EGR passage of the rear end portion of the reformer and measuring a pressure of the exhaust gas of the rear end portion of the reformer; and a reforming controller adapted to determine whether reforming is continued based on a pressure difference between the front end portion and the rear end portion of the reformer measured by the front end and rear end sensors.
