The invention relates to the field of engineering, in particular to designs combined power plants.

A known design for the energy of the processed gases of the internal combustion engine ( patent Germany 2941902, CL F 02 G 5/02 4. 10. 78). The device includes a flywheel driven turbine operating on the exhaust gases of the engine, the clutch switching is located between the gas turbine and flywheel. The flywheel may be coupled with a mechanical machine through pevnosti due to low compression and no pressure atomisation of the fuel.

Known design compressor diesel (Gagarin E. I. Rudnev, S. C. Heat engines. M State. nauch.-technology. published by the engineering literature, 1949. C. 282-288), consisting of a crank mechanism, compressor, compressed air tank, fuel pump, pneumothoraces and pipelines.

When many advantages compressor diesel, namely megatoplist, low toxicity and high inrush quality, because of the high cost of power for the mechanical drive of the compressor is the direction in dvigatelestroenii not received further development.

Also known construction of a combined power plant ( patent Germany 3234 679, CL F 02 G 5/04 from 18.09.82.), selected as a prototype, consisting of any fundamentally different heat engines ( mainly used gasoline engine and a Stirling engine ). Gasoline engine and the Stirling engine can be accommodated in the dormitory or in two closed apart buildings and transmit its power through the connected power flow or through two separate flow. Combined power plant improves the performance of a heat engine and is particularly suitable for stationary UNL high fuel consumption, which is due to imperfect mixing in power plant and, as a consequence, the presence of high toxicity. A significant drawback is namevaluelist installation, which also follows from imperfect mixing and application of low degrees of compression in the engine. Low compression is also a cause of low starting qualities, its growth prevents the growth of mechanical and thermal loads on the engine parts.

The technical result achieved by the invention is the reduction of fuel consumption, ensuring megatoplist, low emissions and improved starting qualities by increasing the degree of compression, perfect system of mixing by using heat of exhaust gas compressor diesel.

This goal is achieved by the fact that the power plant includes an internal combustion engine, representing a diesel with compressor fuel injection, exhaust manifold which is in communication with the heater head of the Stirling engine. The Stirling engine combined with the compressor, i.e., represents the engine compressor Stirling. The compressor cylinder associated drobopro is a, for example, the brake system, tire filling, pneumovirinae car.

Using compressor engine compressor, driven by the Stirling engine due to the heat emitted by the exhaust gas, avoiding the disadvantage that resulted in 30-ies of the reason for abandoning the use of these engines. This disadvantage is the high percentage of loss of useful capacity compressor diesel mechanical drive of the compressor.

In the inventive power unit, the fuel consumption reduction is a consequence of using the heat of exhaust gases and pressure atomisation of the fuel. The pressure atomisation of the fuel in the cylinder of the compressor diesel engine ensures optimal mixing of fuel with air and, as a consequence, complete combustion of fuel with minimal release of toxic substances.

Megatoplist the inventive power unit allows up to 71% of the fuel oil fractions, whereas gasoline engines together only 54% Megatoplist provides the ability to create high degrees of compression in the cylinders of the compressor diesel, 1.5-2 times more than in modern DIGEM create high degrees of compression in compressor diesel engine, are also high starting quality of the power plant.

Comparative analysis with the prototype shows that the proposed power plant differs from the known presence of a new node thermocompressor compressor, made in one piece with the Stirling engine, and their relationship with the compressor diesel.

Thus, the proposed device complies with the criteria of the invention of "novelty."

The comparison of the proposed solutions with other technical solutions showed that the power plant with the use of heat processed gases are widely known. However, structural differences between the claimed power plant of the above, give the power setting new properties, namely efficiency, megatoplist, low toxicity and improved starting.

This allows to conclude that the technical solutions according to the criterion of "significant differences".

In Fig. 1 presents a schematic diagram of an installation that includes an internal combustion engine with the compressor fuel injection 1, an exhaust manifold 2 which is in communication with the heater head of the Stirling engine 3, made in one piece with the compressor 4, salami compressed air 8, for example, brake systems, tire inflation, pneumovirinae cars.

The power plant operates as follows: when the internal combustion engine with the compressor fuel injection 1, the exhaust gases in the exhaust manifold 2 are going to the heater head of the Stirling engine 3, thereby heating it and thereby the operation of the Stirling engine, which is made for the free piston engine compressor (Fig. 2, where 1-piston, 2 - displacer, 3-heater, 4-regenerator, 5-cooler, 6 - gas spring). The power element of the Stirling engine piston, making reciprocating motion of the compressor 4. A compressed air pipe 5 enters the receiver 6, where it accumulates and pipeline 5 is supplied to pneumothoraces 7. Pneumothoraces 7 exercise pneumonitis fuel into the cylinders of the compressor diesel engine 1, thus ensuring its work. From receiver 6 air piping 5 (if necessary) is taken and for other consumers 8: brake system, tire inflation, pneumobilia car.

Power installation comprising an internal combustion engine, an exhaust manifold which reports what orania used diesel compressor with fuel injection, and the Stirling engine is made for the free-piston engine-compressor, while the power plant is equipped with air receivers and piping to supply Pneumofore diesel and other consumers of compressed air.
