Abstract

The invention relates to the operation of an electric vehicle with a micro gas turbine for generating the required for the drive primary energy. Thus, the current required for the electric motor is generated by a generator.

Description

function example

Although the electric motor vehicle drive has some advantages over vehicles with internal combustion engine. However, as the disadvantages of e-mobile for use in general road traffic outweigh the e-mobile remain a minority.

Since the e-mobile for road traffic consuming, expensive battery packs need and still come with it to an acceptable range, were from the designers simple e-mobile upgraded by technical additions to mixed versions (with hybrid drive or range extender).

Even with such gifts were not all e-mobile disadvantages eliminated. Other disadvantages are usually added again.

The inventive arrangement has a different type of power supply for the electric motor drives.

One or more microturbines in the rear of the vehicle provide the mechanical rotational energy for generators that feed the electromotor front-wheel drive.

The first advantage is that the use of the electric motor is limited in any way just like a car with a standard internal combustion engine.

The second advantage is that a heavy, expensive package of various batteries is eliminated.

The third advantage is that the combination of electric motor with micro gas turbine and generator performance is not inferior to the internal combustion engine and also represents a full-fledged solution over the e-mobile auxiliary structures with range extender or hybrid drive.

It is emphasized that 100 kW of power can be demanded from a small micro gas turbine with a length of approx. 1 m and a diameter of 40 cm.

A simple design of MGT with generator provides this power in continuous operation with about 100,000 rpm without any problems.

For the construction according to the invention is provided to keep this rotation with the Stromaustoß of the generator permanently.

In order to optimize performance and consumption of the new design, a process structure with process implementation devices and process execution is provided for analyzing and optimally coordinating all functional properties of the MGT rotational process energy and exhaust heat energy generations.

Since a maximum current flow is permanently generated, but the motor vehicle pilot requires only a portion of the current according to the respective driving conditions, an inverter processor is provided. This assigns the required for the particular driving by the motor vehicle pilot electric motor power component. It is intended to direct the remaining amount of electricity to a small number of batteries.

Furthermore, it is provided that the power consumption of the board consumers from the generator current and / or the battery current is provided via converter processor programming.

The claims 1 to 4 give the expert information about the proposed extensive analysis and voting work, so that a pre-series is tested in practical use.

It should be emphasized that initially 2 small MGT are provided. For each combustion chamber a plurality of ignition points are distributed over the combustion chamber.

A pre-programmed ignition processor clocks the ignition optimally.

This leads to an absolutely uniform combustion process over the entire combustion chamber interior, with the advantage of optimum fuel utilization, lower exhaust gas volume, lower exhaust heat and lower exhaust gas pollutants.

The overall sequences are also optimally timed via the shared recuperator of the two MGTs provided. This also helps to further optimize the combustion processes in the combustion chambers.

The output of heat energy is thereby reduced to a residual minimum.

As is known, part of the exhaust heat energy is conducted via the recuperator to preheat the fuel mixture. However, the recuperator processor clock system according to the invention has the specialty, so that the one of the common heat from MGT 1 and MGT 1 always receives the one MGT, the exhaust gas preheating from the other MGT. As a result, the thermal energy residues are used advantageously, whereby the energy conversion in the combustion chambers is even more advantageous.

It is intended to supply the remaining residual heat energy TEGs thereafter (thermoelectric generators).

It is planned to lower the exhaust gas pollutants to a value that is far below the values of conventional motor vehicles (about 50% are possible).

Procedures with process design, implementation procedures and implementations to analyze and reconcile energy production and transformation

Are known motor vehicle with electric motor drive for road traffic. However, these are in the minority because they have disadvantages compared to fuel-powered vehicles. A particular disadvantage is that e-mobile need a heavy, expensive package of batteries to power the electric motor. However, even with a relatively large battery pack, the range with such power capacity remains very limited.

Relative improvement bring the combinations either with additional hybrid drive or with Range Extender.

Both combinations are not ideal. Although they bring some additional benefits but also some new disadvantages at the same time.

The object of the construction according to the invention is an e-drive concept for motor vehicles, which has none of the disadvantages of the aforementioned electrical power supplies, but an e-mobile vehicle that has no disadvantages compared to the conventional, fuel-powered motor vehicle.

The object is achieved in that a micro gas turbine of the smallest dimensions, with the lowest exhaust gas heat values, lowest pollutant emissions and favorable fuel consumption by means of rotor power transmission to a generator supplies the supply current for the electric vehicle drive.
