ITFR20110004A1 - EMISSIVE LOW EXHAUST, INTENDED FOR THE REDUCTION OF EXHAUST GAS EMISSIONS, DUST AND EVERY OTHER REMAINING OF THE COMBUSTION OF THE MOTOR OF THE MOTOR VEHICLES AND OF ANY MEANS OF TRANSPORT OR LOCOMOTION. - Google Patents

Description

Description of the invention entitled: "Low-emission muffler, intended for the reduction of exhaust gas emissions, dust and any other residue from the combustion of the motor vehicle engine and any other means of transport or locomotion",

The field of application of the invention can be identified in the components of motor vehicles and transport in general, intended for the reduction of exhaust gas emissions, dust and any other residue from engine combustion, in order to reduce or eliminate their release in the 'atmosphere

Various procedures for reducing the emissions of such residues are known (in the state of the art), such as for example catalytic converters or FAP system.

These systems have not produced satisfactory results and the problems encountered are various. Both the functionality of the DPF and the catalytic converter are linked to the use of the car, and only after long journeys and the consequent reaching of high temperatures do they produce satisfactory results, while the results and cleaning of the component on short journeys are poor. .

In general, every type of muffler produced today has a filtering system and silencer made of glass wool in its terminal part.

The major drawback in existing processes can be summed up in the scarce possibility of obtaining adequate levels of emission reduction, due to the difficulty of cleaning the filter inserted in the component itself.

The findings used to date in the state of the art do not allow to replace the terminal filters from the mufflers when these are saturated with dust, a state in which filtering is impossible. They therefore become inefficient over time, and throughout their remaining duration.

With the system covered by this deposit, it is not necessary to act on the motor and it is not necessary to make mechanical or electrical modifications to it. Furthermore, the system covered by this deposit does not affect the performance of the engine, nor the emission reduction systems already present on the vehicles (eg FAP).

The system covered by this deposit has a simple and inexpensive installation and it can also be used on old cars, having any type of fuel, as there are no contraindications relating to the fuels used. The utility of the present invention is to allow the replacement of the filter through simple mechanical and periodic intervention, at low cost and on all vehicles, even those particularly worn, without necessarily having to replace the entire muffler.

The system covered by this deposit is also adaptable to heavy vehicles (eg. Buses, Trucks, Tractors, and any other means of work and transport) with the same simplicity.

The structure has the characteristic of being decomposable into its parts.

The main construction elements are:

1. External cylindrical body (Table 1 - A) made of any metal material or with equivalent characteristics;

2. Flanged inlet pipe (Table 1 - B) made of any metal material or with equivalent characteristics, intended for the entry of fumes.

3. Flanged exhaust pipe (Table 1 - C) made of any metal material or with equivalent characteristics, intended for the smoke outlet.

4. Narrow mesh (Table 1 - D), made of any metal material or with equivalent characteristics, useful in order to contain the filtering materials

5. Steel wool (Table 1 - E) or any other material useful for the purpose of filter.

6. Glass wool (Table 1 - F) or any other material useful for the purpose of filter.

7. Welds (Table 1 - G)

8. Self-locking screws or other equivalent locking / locking system (Table 1 - H)

The invention and each of its components may have various shapes and sizes, such as to adapt to the vehicles for which it is required to be used, adaptable to cars, heavy and public means of transport.

The invention can be modified while maintaining the inventive concept underlying it, each detail being able to be replaced with another technically equivalent one.

Furthermore, the drawings and parts described are given solely for the purpose of illustration and do not constitute a limitation thereof.

In summary, the invention represents a new method for reducing exhaust gas and dust emissions from motor vehicles in general, which thanks to the ease of its opening through the parts (Tables 1 - A-B and A-C) equipped with screws, and consequent inspection of the condition of the internal filters, may be subjected to suitable and economical replacements of the filters themselves when they are considered saturated, in order to recurrently restore the full efficiency of the muffler in terms of silence and retention of harmful substances for the environment.

Currently, in cars and in every other vehicle on the road, this objective can only be reached with the complete replacement of the muffler, given the impossibility of accessing its interior due to the welds, which make it a "single piece". The replacement of the muffler, in addition to being in fact uneconomical, is normally determined when it is damaged, which results in the scarce environmental impact of a device that is truly decisive for public health, such as the muffler itself, if properly overhauled.

The system object of this deposit allows the inspection and replacement of the filter only, improving the usefulness of the car component "muffler", until now not subject to changes and ordinary maintenance, as is the case for many other parts of the vehicle itself. .

The assembly of the invention takes place after inserting the filter (Tab.1 - D-E-F) inside the cylindrical steel body (Tab.1 - A), the tightening of the smoke inlet element by means of bolts (Tab.1 -B), to element A (Table 1 - A) and element C (Table 1 - C) flue gas outlet, with the cylindrical body (Table 1 - A).
