(54) MULTI-CYLINDER ENGINE WITH EXTERNAL HEAT SUPPLY

one

The invention relates to engine-building and can be used in multi-cylinder engines with an external heat supply.

Multi-cylinder engines with an external heat supply are known, which contain a crankcase with radially mounted cylinders and a transforming mechanism associated with suspension, each of which is placed in. one of the cylinders divides its internal cavity into two chambers: cold and hot, highways, each of which is connected to opposite chambers of neighboring cylinders and equipped with a cooler, a regenerator and a heater, and a combustion chamber connected to the heaters and, to one of surface surfaces of each regenerator 1.

Engines are known to be highly compact. However, special-. Such heat supply from the combustion chamber to the heaters and regenerators does not allow to fully utilize the advantages of engine components.

The aim of the invention is to improve the compactness of the engine.

To achieve this goal, the combustion chamber in the engine is designed as autonomous sections according to the number of lines, each section being independent. complete with heater, regenerator and

5 cooler of one of the lines is grouped into a block in which the regenerator case is built into the bottom of the autonomous section of the combustion chamber, and the latter is made perforated, covering with a gap

.- regenerator housing.

FIG. 1 shows the engine, a general view; in fig. 2 - block, longitudinal section. The engine comprises a crankcase 1, cylinders 2 mounted thereon with pistons 3 of double action separating a cavity.

15 cylinders 2 into two working chambers: hot 4 and cold 5, while the pistons 3 are kinematically connected with a transforming mechanism, for example, the Balandin mechanism, and are shifted in phase from each other by 90 °. The opposite chambers of adjacent cylinders 2 communicate via lines with a heater 6, a regenerator 7 and a cooler 8. To each heater 6, an independent section 9 of the combustion chamber is connected, with section 9, heater 6,

the regenerator 7 and cooler 8 are grouped into a single unit, in which the case 10 of the regenerator 7 is built into the bottom 11 of the autonomous section 9 of the combustion chamber. The bottom 11 of section 9 is made perforated, covering with a gap 12 the housing 10 of the regenerator 7. Each autonomous section 9 of the combustion chamber is equipped with an air heater 13, in which the air ducts are connected to the intake manifold 14, and the channels for the combustion products are connected to the exhaust manifold 15. K The intake manifold 14 is also connected through the annular channel 16 to the cavity of the gap 12 between the housing 10 of the regenerator 7 and the bottom 11 of section 9. When the engine is running, air enters the intake manifold 14, then into the heater 13, where it heats up aritelno then fed into the combustion zone battery section 9 of the combustion chamber. At the same time, through the annular channel 16, air also enters the cavity of the gap 12 between the housing 10 of the regenerator 7 and the bottom 11 of section 9 to prevent them from burning.

Through the internal channels of the heater 6, the regenerator 7 and the cooler 8, the working fluid is pumped into the corresponding chambers of the cylinders 2 to operate the engine, and with the radial 3 moving due to the pressure drop in the hot 4 and cold 5 chambers of each cylinder 2, the power is removed transmitted through a conversion mechanism to the consumer.

Thus, the implementation of the combustion chamber in the form of autonomous sections and combining them together with the engine heat exchangers into a single unit improves the compactness of the multi-cylinder engine.
