Abstract: PURPOSE: A variable cylinder engine system with twin crank shafts and control method thereof are provided to reduce fuel consumption as the output of at least four banks is respectively generated to be used for vehicles. CONSTITUTION: A variable cylinder engine system with twin crank shafts comprises a first engine(1), a second engine(3), and a power conversion unit(7) The first engine comprises two banks with twin crank shafts(12) operated by a start motor(14), and comprises a torque output shaft(2) which delivers the output of the two banks a transmission(8). The second engine comprises another two banks with the twin crank shafts operated by the start motor, and comprises a connection output shaft which delivers the output of the another two banks to the torque output shaft. The power conversion unit delivers the torque of the connection output shaft to the torque output shaft by an engine control unit.
