Abstract
A twin engine improves fuel efficiency in a low-load section and generates sufficient output in a high-load section by selecting a specific bank or operating all of the banks in accordance with necessity of required load. The twin engine may include a plurality of engine banks that independently operates in a unit of a cylinder block equipped with a plurality of cylinders, transmissions that are provided at the same number of engine banks and disposed between output ends of engine banks, a power controller that selectively collects the power output from the output ends of transmissions and transmits the power to driving wheels, and a driving controller that controls the operations of the engine banks and the power controller, such that the engine banks are selectively or simultaneously operated in accordance with traveling conditions.
