Description
DESCRIPTION
A FEEDING SYSTEM Field of the Invention
The present invention relates to a feeding system which can use waste heat, fuel and electric energy used in vehicles and generate stable compressed air. Background of the Invention
The control of turbo-compressor systems operating with waste heat is difficult, they are dependent on vehicle engine speed, they are not activated in low speeds, they are deactivated at high speeds so that the engine gets out of control, they require by-pass system when they are deactivated, and this situation increases cost and causes to get less efficiency from the waste heat of the engine. Some turbo compressor systems operate more efficiently by generating less turbo charger air than waste heat capacity in case of high engine speed with movable fin system with higher cost, however this situation decreases the waste heat using capacity. The heavy turbo cannot be activated at low engine speeds although they generate high pressure turbo charger air; the light turbo cannot generate turbo charger air at a pressure that can provide high efficiency although they can be activated at lower engine speeds. Double propeller (light+heavy) turbo compressor systems are high cost and their weight is high. The cost of the supercharger systems .with high pressure driven from the motor shaft is high, they cause excessive fuel consumption, they operate depending on the engine speed and they are hard to control. Generally, an additional turbo compressor system that will operate at high speeds is required, and this situation increases the vehicle cost very much. Electrical supercharger systems require electrical installation cost in addition to the turbo charger, they cause extra electric consumption, and this situation causes extra fuel consumption. Electrical turbo compressor systems operating with
hybrid waste heat cannot utilize engine waste heat at low speeds, they only operate with electrical energy; for this reason they cause to consume more electricity than consumed at high speeds, this situation also causes the requirement for an alternator driven by the motor shaft. They cannot respond to the situations requiring long term electric consumption (for example need for generator for trailer type vehicles or electric energy needed during picnic) when the vehicle is not working. Furthermore, if a system is not installed, it is not possible to heat the vehicle cabin before the engine water reaches a predetermined degree, and the cooling-air conditioning systems operating with waste heat installed on the vehicle cannot function.
United States Patent Document no US2010281863 (Al), an application known in the state of the art, discloses controlling the rotation speed of a hybrid exhaust turbine turbochargers. The system comprises exhaust turbine turbocharger (6) that has a turbine section (6a) and a compressor section (6b). The turbocharger (6) is in an operating mode when an engine unit (2) is in operation. Hybrid exhaust turbine turbocharger (7) that has a turbine section (7a), a compressor section (7b), and a generator (29) is set to operate in parallel with the other exhaust turbine turbocharger (6). A rotation sensor that is attached to the exhaust turbine turbocharger (6) detects the rotation speed of the exhaust turbine turbocharger (6) when the engine is in operation, gives a command signal to the generator (29). Therefore the electricity to be generated by the generator (29) is controlled according to the signal. Summary of the Invention
The objective of the present invention is to provide a feeding system the turbo charger system of which can generate turbo charger air in stable conditions independent from the engine speed.
Another objective of the present invention is to provide a feeding system which can generate turbocharger air by using exhaust heat at low speeds.
A further objective of the present invention is to provide a feeding system which can generate turbocharger air by burning fuel under insufficient pressure and temperature conditions.
Yet another objective of the present invention is to provide a feeding system which can meet long term electric consumption requirement when the vehicle is not in operation, that is which can also operate as a generator.
Another objective of the present invention is to provide a feeding system which enables to heat the vehicle cabin without operating the internal combustion engine and which enables to use the cooling-air conditioning systems operating with waste heat and installed on the vehicle when the vehicle engine is not in operation.

In one embodiment of the invention, the feeding system (1) is comprised of at least one turbine (2) which operates at high speed with low pressure hot gas pressure, at least one compressor (4) which is turbo type and operates by rotating with high speed driven by the said turbine (2) being attached to the shaft (3), a gated combustion chamber (5) through which the hot gases are sent to the turbine (2), a valve (6) which controls the air intake to the said gated combustion chamber (5) from the compressor (4), a by-pass valve (7) which controls the intake of the hot exhaust gases to the gated combustion chamber (5), an exchanger (8) which enables the heat transfer of the by-passed gases to the pressurized air in the combustion chamber (5), an induction system (9), flame kit (10), a high speed motor (11) which operates with electricity, a driver (12) which enables the motor (11) to operate as motor-generator, a controller (13) which sends control signal to the said driver (12), vehicle computer (14) and at least one battery (15) (vehicle accumulator).

While the engine speed is a at a level such that it cannot generate pressure sufficient enough to rotate the turbine (2), some part of the pressurized air generated by the compressor (4) is sent to the gated combustion chamber (5) via a valve (6). In this case, the by-pass valve (7) is turned on since there is no enough pressure and the exhaust gases are discharged from the exchanger (8). The pressurized air compressed by the compressor (4) is heated by being passed through the said exchanger (8) and the propeller of the turbine (2) is driven. In this way, the pressurized air is generated by using the temperature of the exhaust gas. In case there is no enough exhaust gas temperature, the turbine (2) and the compressor (4) is supported by the motor (11). At high speeds, when the pressure and amount of the air coming out of the compressor (4) increases, the motor (11) is operated as generator by the driver (12) and the battery (15) of the vehicle is charged with the electricity which is generated as extra. When the vehicle is not operating, when there is a need for long term electric use, the compressor (4) and the turbo turbines (2) are activated with the motor (11), the all of the pressurized air generated by the compressor (4) is given to the gated combustion chamber (5). The fuel pump is operated in low capacity, actual vehicle engine (M) fuel system is not activated, the fuel is sprayed to the volume of the gated combustion chamber (5) and the fuel is ignited with the flame kit (10). In this way, the pressurized air compressed by the compressor (4) is heated and expanded in the turbine (2). Some part of the energy received from the turbine (2) is used while maintaining at a pressure of the air compressed by the compressor (4) in a certain value, the extra torque enables the electric motor (11) controlled by the driver (12) to be operated as a generator, and the electric generation is carried out. The burnt gases are discharged from the exhaust system through the turbo outlet. The said hot air can also be used in cooling-air conditioning systems operating with waste heat, if present, in order to heat the vehicle cabin without operating the engine via an exchanger (8).
