POWERTRAIN FOR INTERNAL-COMBUSTION ENGINE VEHICLE WITH COMBINATION OF PISTON ENGINE AND ROTARY ENGINE

摘要

Disclosed herein is a powertrain for an internal-combustion engine vehicle with a combination of a piston engine and a rotary engine. The powertrain includes a piston engine (10), a transmission (20), and a rotary engine (30). The piston engine (10) is provided as a primary power source. The transmission (20) is configured such that power produced from the piston engine (10) is transmitted to the transmission (20) through an output shaft (1). The rotary engine (30) is provided as a secondary power source and shares the output shaft (1) with the piston engine (10) and transmits produced power to the transmission (20). Power produced from the piston engine and power produced from the rotary engine are simultaneously or selectively transmitted to the transmission. Therefore, the present invention can have the advantages of the respective engines, whereby the performance and fuel efficiency per a unit engine displacement can be maximized.
