The composite engine system is comprised of a main engine in which a composite engine is provided with a plurality of internal combustion cylinders and a plurality of external combustion cylinders installed integrally in one cylinder block and a dual flywheel structure; and one or more subsystems in connection with the external combustion cylinder, in which one subsystem has a closed loop of He gas and other subsystem has two closed loops of HE gas expanded by waste heat gas and a He gas expanding apparatus, whereby the composite engine system has a configuration consisting of a plurality of closed loops of He gas to enhance the net thermal efficiency of the whole engine as well as to lower the temperature of the exhaust gas, and further to have the effect of reducing the amount of exhaust gas resulting from a decreased number of fire cylinders being used.
