Tecnología para reducir emisiones peligrosas de la combustión de motores diésel


Oferta Tecnológica
Un inventor alemán con sede en España ha solicitado una patente para añadir micropartículas y polvo fino peligrosos de motores diésel a un líquido y prevenir las emisiones a la atmósfera. El nitrógeno también se oxida y reduce y los valores de pH son neutralizados en el sistema. La instalación de esta tecnología en el vehículo se realiza de forma sencilla y rentable. El inventor busca fabricantes de repuestos de automóviles con el fin de establecer acuerdos de adquisición, licencia de la patente o cooperación técnica para continuar con el desarrollo. La tecnología puede aplicarse a cualquier motor de gasolina o diésel (locomotoras, barcos, equipos industriales, etc.), por lo que el inventor está abierto a negociar con licenciatarios potenciales de otros sectores: ferroviario, marítimo, industrial, etc.


Technology offered to reduce the hazardous emissions of diesel engines combustion.
A German inventor based in Spain filed a patent (pending solution) to bind the harmful fine dust from diesel engines into a liquid, preventing thus to be blown out into the air. The nitrogen oxides are also reduced and the PH values are neutralized by the system. The required installation in the car is easy and not expensive. Manufactures of car spare parts are sought for acquisition or a license agreement of the patent. Technical cooperation may be offered as well for further developments.
The exhaust of combustion engines contains a number of pollutants that are hazardous to health and contribute to the damage to the environment, such as:

· Fine dust: the fine dust spreads in the air and is inhaled by people. Larger particles fall relatively quickly to the earth, but especially the microfine particles, go into the lungs and sometimes remain there. This is the cause of many cancer cases.
· NOx: the nitrogen oxides are inhaled and form acids in contact with moisture (e.g., in the throat) and thus irritates and and are poisonous.
· PH value: non neutral PH values of the emissions also have harmful effects.

The exhaust gas situation for diesel vehicles is currently being discussed very intensively all across the EU, particularly in Germany, to the extent that there is a real risk of completely prohibiting diesel vehicles in city traffic. Should that happen it would be very attractive for the owners of diesel cars to have a solution in the market able to put their car emissions into the permitted limits, converting thus their vehicles and avoiding any bans or driving restrictions.

The automotive industry is currently working on the solution to reduce some of the harmful elements of the emissions. NOx values, for instance, are tackled by spraying ammonia into the exhaust gas, a technology that faces important challenges: the exact amount of ammonia shall be sprayed according to the actual power of the engine, otherwise it is also necessary to neutralize the outgoing harmful ammonia. This makes the current solution for NOx reduction difficult and expensive. The retention of fine dust (particles ranging from 0.1 to 15 microns) remains unsolved. Microparticles can technically be filtered, but associated with considerable engineering difficulties. Neutralization of PH levels is so far an unattended problem.

With the aim of offering a solution for diesel car owners before possible legal traffic restrictions, a German inventor located in Spain has developed a system that reduces dramatically the emission of fine dust and microparticles of diesel engine combustion, which also reduces the levels of NOx and helps to regulate the pH levels of the emissions. The system is based on the principle that adhesion occurs when mass (e.g., fine dust) comes in contact with a liquid. This means that the wetted particles remain in the liquid and will no longer return to the gas. The NOx in the exhaust forms nitric acid in contact with liquid, the liquid in the system is treated to raise the pH of the final emissions.

The technology consists of an additional aggregate which can be retrofitted into used and new vehicles, which is suitable for both, diesel and gasoline cars. The installation of the system in the car is very easy, it can be performed at any regular garage: the last muffler (rear silencer) is replaced with a cleaning tank. This is connected with a pipe or hose to the pump on the lid of the swap container. The lid of the swap body is placed in a convenient location, probably in the trunk.

Tests have been conducted to investigate the efficiency of liquids in retaining dust particles from exhaust gas. The results of the amount of dust catch by water-based simple test are shown in figure 4.

The inventor offers the technology mainly to motor vehicle (cars, vans, trucks, buses, etc.) spare parts manufacturers, under patent acquisitioning or licensing. The technology can be applied to any engine powered by diesel or gasoline combustion (diesel locomotives, ships, industrial equipment, etc.), so the inventor is also open to negotiate with potential licensees coming from other sectors than motor vehicles, i.e. railway, maritime, industrial, etc.

Technical cooperation for further develpments is negotiable.

Advantages and Innovations:
Technological innovations
The system gets a considerable reduction of fine dust emissions of diesel engine combustions. The cut of fine particles emission is estimated in 80-90%.
The system also reduces the NOx emissions. The cut of fine particles emission is estimated in 70-80%.
Neutralization of the emission PH is achieved by treating the liquid in the system.

Market advantages
The system can be installed in new vehicles and used vehicles.
The installation of the system is cheap (it can be done within some hour) and easy (it can be performed in any regular garage by any regular motor mechanic).
The discomfort for the drivers is low, as they are only required to replace a liquid container at certain intervals, before the system is saturated.

Partner sought

Type and Role of Partner Sought:
Type of partner sought: industrial manufacturers of motor vehicle (cars, vans, trucks, buses, etc.) spare parts industry.

The technology can be applied in any area where efficient exhaust emission cleaning is needed, particularly those originated by engines powered by diesel or gasoline combustion (diesel locomotives, ships, industrial equipment, etc.). Therefore, the technology is also available to any potential licensee coming from other sectors than motor vehicles: railway, maritime, industry, construction, etc.

The role of the partner sought is to acquire the patent or exploit it under licensing agreement. Technological cooperation for further developments involving the inventor is possible, but it will be dealt during the negotiations.
