Abstract

The process for supplying a vehicle with solar electricity, comprises locating solar cells on the vehicle roof, bonnet, boot lid etc., and connecting them to a regulator and a chargeable accumulator. The electrical energy is used to form hydrogen and oxygen from water. The oxygen is used during a cold start phase. The hydrogen is used in the catalyst as reducing agent for emitted pollutants.

Description

Einleitungintroduction

Kraftfahrzeuge sind mobile Maschinen, die zur Fortbewegung und zur Betätigung ihrer Elemente Energie benötigen. Diese Energie stammt aus dem Kraftstoff, die durch die Verbrennung die in sich chemisch gespeicherte Energie freigibt. Im Grunde genommen kann man behaupten, dass Kraftfahrzeuge mit Bioenergie angetrieben werden, da Kraftstoff nichts anderes ist, als die im Laufe von Jahrmillionen aus Lebewesen entstandene Biomasse. Motor vehicles are mobile machines that are used for locomotion and for operation of their elements need energy. This energy comes from the fuel that releases the chemically stored energy through combustion. Basically taken one can say that motor vehicles are powered by bioenergy since fuel is nothing other than that made over millions of years Living organism created biomass.

Allerdings steht diese Energie dann nicht mehr zur Verfügung, wenn kein Kraftstoff im Motor verbrannt wird. Die Pausen zwischen den einzelnen Betriebsphasen eines Kraftfahrzeuges können energetisch nicht genutzt werden. However, this energy is no longer available if there is no fuel is burned in the engine. The breaks between the individual operating phases of a Motor vehicle can not be used energetically.

In der vorliegenden Beschreibung wird ein Verfahren dargestellt, das die Erzeugung und Nutzung von Solarenergie während des Stillstandes des Motors, also in den Betriebspausen des Kraftfahrzeuges ermöglicht. In the present description, a method is shown that the generation and use of solar energy while the engine is at a standstill, i.e. in the Service breaks of the motor vehicle allows.

Stand der TechnikState of the art

Der Einsatz solarer Technologie erstreckt sich über verschiedene Bereiche wie zum Beispiel die Solararchitektur oder auch die solare Stadtplanung. The use of solar technology extends across different areas such as For example, solar architecture or solar urban planning.

Im Bereich der elektromotorisch betriebenen Kraftfahrzeuge gibt es die Möglichkeit, zur Bereitstellung der Antriebsenergie wiederaufladbare Nickel-Cadmium-Batterien mitzuführen. Diese Batterien lassen sich innerhalb von zwei Stunden an sogenannten Solartankstellen mit Hilfe von photovoltaisch gewonnenem Solarstrom wieder aufladen. Nach Quelle SOLAR + E-MOBIL 96/97 gelingt bei entsprechender Leichtbauweise des Fahrzeugs eine abgasfreie Fortbewegung unter ausschließlicher Nutzung von regenerativer Energie. In the field of electric motor vehicles, there is the possibility To provide the drive energy, rechargeable nickel-cadmium batteries carry. These batteries can be started within two hours so-called solar filling stations with the help of photovoltaically generated solar power recharge. According to SOLAR + E-MOBIL 96/97, the Lightweight construction of the vehicle ensures exhaust-free movement under exclusive Use of regenerative energy.

Bei den autarken Solarmobilen wird die Energie zum Betreiben des elektrischen Antriebsmotors ausschließlich mit dem Sonnenstrom der bordeigenen Solarmodule gedeckt. With self-sufficient solar vehicles, the energy is used to operate the electrical Drive motor exclusively with the solar current of the on-board solar modules covered.

Eine Kombination von Verbrennungsmotor und solarem Elektroantrieb liegt bei den sogenannten Hybridfahrzeugen vor. Generell wird zwischen parallelen und seriellen Hybridantrieben unterschieden. Beim Parallel-Hybridantrieb kann das Fahrzeug entweder nur mit Verbrennungsmotor, nur elektrisch oder aber mit beiden Antrieben fahren. Beispiele sind der Audi duo oder der Golf Hybrid aus dem VAG-Konzern. Beim seriellen Antrieb fährt das Fahrzeug immer elektrisch. Es besteht aber die Möglichkeit, mit einem kleinen Verbrennungsmotor einen Generator anzutreiben, der Strom für Antrieb oder Batterieladung liefert. Beispiele sind der Irmscher Selectra auf Basis des Opel Corsa, der Volvo ECT mit einer Gasturbine oder der Neoplan-Hybrid- Bus mit Schwungradspeicher und Dieselmotor. A combination of internal combustion engine and solar electric drive lies with the so-called hybrid vehicles. Generally there is a difference between parallel and serial Differentiated hybrid drives. With parallel hybrid drives, the vehicle can either only with an internal combustion engine, only electrically or with both drives drive. Examples are the Audi duo or the Golf Hybrid from the VAG group. With serial drive, the vehicle always runs electrically. But there is Possibility of using a small internal combustion engine to drive a generator that Provides power for drive or battery charging. Examples are the Irmscher Selectra on Basis of the Opel Corsa, the Volvo ECT with a gas turbine or the Neoplan hybrid Bus with flywheel storage and diesel engine.

Beschreibung des VerfahrensDescription of the procedure

Eine oder mehrere Solarzellen (1) werden an den geraden Flächen des Kraftfahrzeuges (2) befestigt und die Solarenergie in Solarkabeln (3) weitergeleitet. Der zum System gehörende Laderegler (4) und Akkumulator (5) wird im Kraftfahrzeug in die Stoßstange integriert, s. Fig. 1. One or more solar cells ( 1 ) are attached to the straight surfaces of the motor vehicle ( 2 ) and the solar energy is passed on in solar cables ( 3 ). The charge controller ( 4 ) and accumulator ( 5 ) belonging to the system are integrated into the bumper in the motor vehicle, see FIG. Fig. 1.

Applikationenapplications 1. Spaltung von Wasser1. Splitting water

Für die Verbrennung des Motorwirkungsgrades könnten aus Wasser gespaltener Sauer- und Wasserstoff genutzt werden. In einem Behälter (6) wird Wasser (7) mitgeführt, das mit Hilfe von elektrischer Energie durch Hydrolyse in Wasserstoff (+) und Sauerstoff (-) gespalten wird. Sauerstoff (8) kann bei großer Kälte oder generell während des Startvorganges zur Verbrennungsluft dosiert werden. Wird Wasserstoff (9) in den Katalysator (10) dazu dosiert, kann das den Abbau von Schadstoffen unterstützen, s. Fig. 2. Oxygen and hydrogen split from water could be used to burn the engine efficiency. Water ( 7 ) is carried in a container ( 6 ) which is split into hydrogen (+) and oxygen (-) by means of electrical energy by hydrolysis. Oxygen ( 8 ) can be added to the combustion air in very cold weather or generally during the starting process. If hydrogen ( 9 ) is metered into the catalyst ( 10 ), this can support the breakdown of pollutants, s. Fig. 2.

2. Unterstützung des Entstickungsvorganges in Diesel-Kraftfahrzeugen2. Supporting the denitrification process in diesel vehicles

Zur Entstickung des Abgases (11) im Dieselmotor (12) müssen Maßnahmen mittels Selektiver Catalytischer Reduktion (SCR) vorgenommen werden. Das zur Entstickung notwendige Ammoniak (NH3) (13) kann in den Ruhepausen das Kraftfahrzeuges aus flüssigen oder festen Substanzen, wie verdünntem Harnstoff (14) oder Karbamat (15) durch den Solarstrom (16) hergestellt werden. Das freigesetzte Gas muss bis zum Verbrauch in speziellen Gasbehältern (17) gespeichert werden, s. Fig. 3. To remove nitrogen from the exhaust gas ( 11 ) in the diesel engine ( 12 ), measures must be taken using selective catalytic reduction (SCR). The ammonia (NH 3 ) ( 13 ) necessary for denitrification can be produced from liquid or solid substances, such as dilute urea ( 14 ) or carbamate ( 15 ) by the solar power ( 16 ) during the breaks in the motor vehicle. The released gas must be stored in special gas containers ( 17 ) until it is used, see Fig. 3.

3. Speisung von OBM-Geräten3. Supply of OBM devices

Die Überwachung der Güte des Verbrennungsvorganges im Hinblick auf die Vollständigkeit und Vollkommenheit der Verbrennung und der Abgasnachbehandlung auf Abbau gefährlicher und emittierender Schadstoffe verlangt den Einsatz eines On- Board-Messgerätes (OBM) (18) in Kraftfahrzeugen, s. Fig. 4. Diese Geräte müssen auch während der Betriebspausen der Kraftfahrzeuge eine kurze Kalibrierphase (19) durchführen. Über eine Uhr des geräteeigenen Mikrocontrollers wird dieser Vorgang aktiviert. Das System saugt Luft aus der Umgebung und misst die Nullgas, - d. h. Luftkonzentration und stellt damit die Nulllinie ein. Wichtig beim Betrieb des OBM- Systems ist, dass es den Fahrzeugakkumulator zusätzlich nicht belastet. Monitoring the quality of the combustion process with regard to the completeness and completeness of the combustion and exhaust gas aftertreatment for the reduction of dangerous and emitting pollutants requires the use of an on-board measuring device (OBM) ( 18 ) in motor vehicles, see. Fig. 4. These devices must also perform a short calibration phase ( 19 ) during the breaks in operation of the motor vehicles. This process is activated by a clock on the device's own microcontroller. The system draws air from the environment and measures the zero gas, ie air concentration, and thus sets the zero line. It is important when operating the OBM system that it does not put additional stress on the vehicle accumulator.

4. Betrieb sicherheitsrelevanter Systeme4. Operation of safety-related systems

Der Meldung der örtlichen Koordinaten (20) des Gerätes an eine Zentrale (21) kommt unter sicherheitstechnischen Aspekten eine immer größere Bedeutung zu. Eine Diebstahlsicherung kann und soll auch während der Ruhephase die notwendige Meldung (22) abgeben. Oft wird es verlangt, dass solche Systeme an die Stromversorgung des Kraftfahrzeuges aus Garantiegründen nicht angeschlossen werden. Bereits die Lockerung der Stromversorgungsleitungen am Akkumulator kann zu einer allgemeinen Fehlermeldung in einem OBD-Kraftfahrzeug führen. The reporting of the local coordinates ( 20 ) of the device to a control center ( 21 ) is becoming increasingly important from a safety point of view. An anti-theft device can and should give the necessary message ( 22 ) even during the rest phase. It is often required that such systems are not connected to the power supply of the motor vehicle for guarantee reasons. Even the loosening of the power supply lines on the accumulator can lead to a general error message in an OBD motor vehicle.

Aus den obigen Gründen ist es vorteilhaft, Solarzellen an Kraftfahrzeugen zu installieren, die eine vollkommen autarke Stromversorgung und einen störungsfreien Betrieb, ohne Verletzung der Garantie, gewähren.
