For over 150 years, combustion engines have undergone continuous development and refinement. However, they now face a challenge.

Politically motivated decisions lack understandable, technically and scientifically grounded arguments. Despite this, the combustion engine can still contribute to the advancement of electromobility.

Electric mobility is not yet capable of completely replacing mature combustion engines, although the obvious advantages of electric motors are undisputed.

The main problem in the otherwise ingenious and simple solution of electromobility lies in the power supply of the electric drive—the accumulator. Issues such as limited range when fully charged, long charging times, and an underdeveloped network of battery charging stations remain unresolved.

As a bridging technology, a "range extender" approach presents itself. Numerous methods have been proposed to increase the actual range of a fully charged accumulator from approximately 150-250 km to the desired 800-900 km.

Considering that current lithium accumulators are a standard technology and significant advancements in accumulator innovation are not yet visible, bridging technologies aim to provide a solution.

SDT Industrial Technology has filed several patents for aircraft engines in the field of air mobility. One of these patents has just been granted.

This patent represents a significant increase in the efficiency of an internal combustion engine by utilizing the waste heat, specifically the thermal energy of the exhaust gases, in the usable energy balance of the engine. This results in an increase of the efficiency ratio (n=usable energy / fuel energy) up to 80% (most internal combustion engines: max 40% for gasoline or 43% for diesel, actual efficiency values typically range between 20-30%).

In simplified terms, the innovative SDT aircraft engine design involves introducing the exhaust gases from an internal combustion engine into a mixing chamber via an air compressor directly driven by the engine. Within the mixing chamber, the heat from the exhaust gases is transferred to the gas-air mixture, which is then supplied to a turbine-like device. This device can either have a nozzle for propulsion or an output shaft connected to an electric generator. In this setup, the internal combustion engine and the air compressor are mechanically decoupled from the electric drive (electric motors).

The SDT aircraft engine can efficiently operate an electric generator, serving to power electric motors and/or charge accumulators.

Additionally, the combustion engine can be operated within an optimal speed and consumption range, avoiding load changes and eliminating the need for a gearbox (manual or automatic). As the combustion engine operates within a specific speed range independent of the vehicle's movement, it acts solely as an energy source for charging the accumulator and supplying electric energy to the vehicle's electric motors. This results in a particularly efficient, fuel-efficient, long-lasting, low-noise, and low-emission combustion engine operation.

Furthermore, the exhaust gases of the SDT combustion engine release their thermal energy as useful kinetic energy. After completing their work and undergoing subsequent cleaning, the exhausted air-fuel mixture is released into the atmosphere, with its temperature decreasing to nearly match the ambient temperature.

Returning to bridging technologies, specifically the "range extender":

The SDT aircraft engine can be used as a drive system for an electric generator to charge the accumulator of an electric vehicle. This enables a significantly increased range and independence from charging stations (as well as lengthy charging times).

Theoretically, any electric vehicle can be retrofitted with an SDT engine as an electric generator, allowing it to be fully refueled with diesel or gasoline at any regular fuel station in a matter of minutes, without the need for charging at an accumulator station. This setup enables remarkable fuel efficiency (combined with comfortable electric mobility) at approximately 0,35 liters in 1 hour. With a fully filled fuel tank of approximately 20 liters, a relaxed journey with a range of up to 3,000 km becomes possible.

The practical implementation of such a technical solution relies on proven, mass-produced combustion engines (diesel or gasoline), as well as already evaluated electric motors and available Li-ion accumulators.

The SDT solution should be viewed as a bridging technology, providing an immediately deployable and secure technical solution. The scientific and technical developments forming the basis of the SDT patent claims enable the prompt implementation of corresponding measures for mobility extensions, thus facilitating the widespread adoption of electromobility.
