THERMAL ENGINE OPERATION AND ITS DESIGN Russian patent published in 2008 - IPC F02B53/02 F02B47/02 F02B41/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production. The operation of the rotary thermal engine with tight variable-volume chambers and an actuator making a piston, includes four strokes of internal combustion engine, plus a stroke of injection in the power stroke chamber, a combustion chamber, of water. Injection of water is effected after combustion of a fuel mix before the termination of the power stroke resulted from burned fuel. The power stroke is elongated by making the actuator, the piston, travel over longer distance compared to the compression stroke. Quantity of injected water is metered out depending on temperature and pressure of gases at the moment of injection. The exhaust of waste vapor-gas mix is subjected consecutively to condensation in the condenser, cleaning of formed water in the filter and feed of the cleaned water again in the engine for injection. Injection of water is effected after its preliminary heating. The rotary thermal engine contains a stator, a rotor, mobile partitions, a combustion chamber, an atomiser for injection of water and a water feed device linked with the rotor.

EFFECT: higher engine efficiency and lower exhaust to toxicity.
