Abstract
Abstract A rotary internal combustion engine comprising a stationary, water cooled housing having a large cylindrical bore in which a hollow cylinder with end walls rotates at a uniform speed. On said cylinder a pair of wedge-shaped pistons is mounted diametrically opposed to a similar pair of reactor elements carried by a multiple-splined shaft, said reactor elements and said pistons forming a combustion chamber whereby a gas and air mixture is compressed prior to ignition, whereupon said reactor element moves several degrees oppositely to the uniformly rotating piston while expansion is taking place. This short reverse rotation of the reactor element is derived from a gear mechanism which provides a short period of reverse rotation and a longer period of rotation in the same direction as the piston, but at a higher speed, whereby the burned gases will be exhausted as the reactor element approaches its mating piston and/or compresses the intake mixture of gas and air between the other pair of piston and reactor element before a second ignition takes place during one revolution of the cylinder.
