<p>There is claimed an engine of the adiabatic type. It is an object of the invention to enhance economical operation of the engine. The novelty of the invention consists in provision of two additional strokes for intra-cycle forced cooling of the engine (E) and injection of the air into cylinders. The engine comprises additional passages (AP) communicating the spaces of cylinders (C) and cooling jacket (CJ), AP overlap valves, a distribution device and its drive from a crankshaft with a gear ratio: 2: (S+2), where S is the original number of E strokes. CJ comprises volute chambers and is filled with air (A) or fuel-air mixture used in the capacity of a cooling medium (CM) for cooling and supercharging E due to a pumping action in two additional strokes. The engine can comprise injectors connected in series with admission P, the active gas paths thereof communicate these injectors via AP with CJ for injection of A into C at the expense of CM energy. There is provided a boost receiver connected with C and CJ spaces via pressure and discharge paths, with the controlled valves installed therein, for non-inertia increase of the supercharging pressure when E load abruptly changes and for facilitation of E starting by means of the supply of compressed A from the receiver into CJ. The rate of fuel consumption decreases by about 30 % in comparison with conventional engines. <IMAGE></p> |
