FIELD: mechanical engineering; internal combustion rotor engines.
SUBSTANCE: according to invention, water, after cooling of engine working members, is delivered to heat-insulated compression chamber after closing on intake hole. Then mixture is directed into heat-insulated combustion chamber, and remaining water is directed into heat-insulated expansion chamber during working stroke from engine housing and piston. For this purpose engine housing is provided with mechanism to deliver water into expansion chamber, and one of engine covers is provided with mechanism to deliver water into compression chamber. Outlet hole of combustion chamber has calibrated holes to let out piston cooling water. Outlet hole of expansion chamber has area not less than cross section of expansion chamber and is provided with guide vanes.
EFFECT: increased efficiency of engine in operation.
