Abstract: A rotary engine includes a housing, a crank dual-slider connecting rod mechanism, and rotary casings. The vertically arranged sliding grooves are provided in the housing. The crank dual-slider connecting rod mechanism is mounted on the housing. Sliders of the crank dual-slider connecting rod mechanism are respectively located in the sliding groove. The sliders are driven by a rotation of a crank to periodically compress a gas in the sliding grooves. The two rotary casings configured to rotate synchronously are mounted on an outer side of the housing. Each of the rotary casings is provided with a combustion chamber. Any of the rotary casings is in a transmission connection with a main shaft via a transmission system. The rotary casings drive the main shaft to rotate through a combustion of a compressed gas in the combustion chambers. The rotary engine achieves a good seal.
