FIELD OF THE INVENTION The invention relates to mechanical engineering, in particular to engine-building, in particular to engine supercharging systems.

The purpose of the invention is to increase the effective performance

The drawing shows a diagram of the power plant.

The power plant contains a diesel engine 1 with an intake pipe 2 and exhaust manifold 3, a turbocharger 4 aspirated diesel engine 1 with a compressor air-inlet pipe connected to the intake pipe 2, an exhaust gas pipe and a gas inlet pipe of the turbine connected to the exhaust manifold, an additional combustion chamber 5 connected to the gas inlet pipe of the turbine and connected to the line 6 of the air supply through the valve block 7 from the compressor’s air-inlet pipe, a power turbine 8, kinematically connected with The diesel engine 1 is connected with its turbocharger 4 turbine 4 and its air inlet pipe 9 through the supplementary body 10 from the compressor. The installation is equipped with an additional combustion chamber 11 installed between the inlet pipe of the power turbine 8 and the gas outlet pipe of the turbine of the turbocompressor 4, the air 9 bypass line from the compressor is connected to the air pressure pipe of the latter and through the second additional combustion chamber 11. The first additional combustion chamber 5 is connected to the exhaust manifold 3 and is located between the exhaust manifold 3 and the gas inlet pipe of the turbine of the turbocharger 4.

The installation works as follows.

When the diesel 1 is inoperative, the first additional combustion chamber 5 is turned on and the turbocharger 4 is started up. The autonomous operation of the turbocharger 4 is maintained by supplying fuel to the first additional combustion chamber 5. To start diesel 1, a second additional combustion chamber 11 is turned on by supplying it with fuel and air via a bypass 9 from the compressor. From the second additional combustion chamber 11, the power turbine 8 is started, which spins up the diesel engine crankshaft 1, ensuring the launch of the latter. This eliminates special starting devices and simplifies the design of the power plant.

When operating diesel 1 in the entire range of speed and load modes silovch

the turbine 8 transmits to the diesel engine crankshaft 1 the power obtained due to the continued expansion of gases in the power turbine 8. Thereby increasing

installation efficiency. In addition, an intermediate heat supply to the working fluid in the second additional combustion chamber 11 determines an increase in the cycle efficiency by approximating the expansion process to

turbines to isothermal

The operation of the installation with the rotation of the crankshaft of diesel 1 with a frequency less than minimally stable is provided at

simultaneous supply of fuel to both additional combustion chambers. The power turbine 8 develops enough power to rotate the crankshaft of a diesel engine 1 at a frequency that is less than the minimum stable one.

Improving the performance of a power plant by expanding the speed range of a diesel engine can reduce the size of the vehicle's gearbox, simplify the design of the power plant, and improve its effective performance.
