摘要： A composite intake system and method of operating a rotary engine with variable intake manifold is provided. The system includes two switching valves in a secondary intake switching tube to change the intake method. When the rotary engine works under low speed conditions, it adopts the long intake manifold and the side-intake mode. When the rotary engine works under medium and high speed conditions, it uses the short intake manifold and the composite-intake mode. When the rotary engine works under ultra high speed conditions, it takes the short intake manifold and the peripheral-intake mode.

摘要： 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.

摘要： The present invention belongs to the field of flame arresters, and discloses a buffered wall flow multi-channels flame arrester. The flame arrester comprises a buffering and splitting cover and a Z-type wall flow multi-channels flame arresting core, wherein the buffering and splitting cover has a round-bottom plain-top cylindrical shape or hemispherical shape, with pinholes distributed in the cover surface, and channels are arranged inside the Z-type wall flow multi-channels flame arresting core. In every two adjacent channels, the inlet of one channel is blocked, and the outlet of the other channel is blocked, and in the height direction in the central cross section of the flame arresting core, pinholes are arranged in the wall surfaces between adjacent channels, and adjacent upper and lower channels constitute a fluid channel.

摘要： An actuator of a rotary engine that can realize different compression ratios includes three parts: an eccentric shaft, a triangle rotor and a control system. The eccentric shaft includes the front part of the eccentric shaft, the combination of an electric three-jaw and the rear part of the eccentric shaft. The triangle rotor includes the variable volume actuator, the front part of the rotor and the rear part of the rotor. The control system controls expansion and contraction of the electric three-jaw. The eccentric shaft part passes through the triangle rotor part to make the combination of electric three jaw to arrange in the annular groove. The reciprocating motion of the variable volume actuator is controlled by the expansion and contraction of the claw top of the electric three-jaw. Engine compression ratio may therefore be adjusted using the compression ratio adjustment system.
