Abstract

The eco filter system of an IC engine represents a combination of the absorbing outlets (1), the absorbing branch (3) with the attached ventilator (4) that absorbs exhaust gases of the other motor vehicles that are transmitted with a pressure pipe (6) to the filter (5). The filtered exhaust gas is passed on further more with the pressure pipe (6) through the irreversible valve (10) and the nozzle (11) to the exhaust pipe (7). The nozzle (11) is the ending of the pressure pipe (6) and is placed in the exhaust pipe (7) of the motor vehicle. If it is required, depending on CO2 concentration in air the CO2 sensor (2) transmits a signal to the control unit (9) hence turns a function of the ventilator (4) on/off. Furthermore, depending on a CO2 sensor (2) signal the control unit (9) transmits to the motor vehicle dashboard signal indicator the information about a function of the eco filter system of IC engine.

Description

ECO AIR FILTER SYSTEM OF INTERNAL COMBUSTION ENGINE
Technical field
The invention relates to a filter system installed inside a motor vehicle with an internal combustion engine (IC), classified according to the International Patent Classification (IPC) as Int. class F 01N3/033.
Background Art
There is usually a lot of traffic jam and congestion in most cities, particularly at traffic lights and spots where normal and smoothly flowing motor vehicles are blocked. The main sources of air pollution are household heating, industry, and traffic. The most common pollutants are carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2), microparticles of soot. The specific air pollutants are lead, cadmium, manganese, arsenic, nickel, chromium and heavy metals and organic compounds that are formed as a result of different reactions. Carbon monoxide (CO) is a highly toxic, colorless, odorless, and tasteless gas. This gas is produced during incomplete combustion of fossil fuels. In the air, 1% of carbon monoxide (CO) concentration is deadly. Due to pollution, the air of cities has become stuffy and impure providing poor living conditions. The levels of emission of gases are related to fuel consumption, fuel quality, combustion techniques, cleansing techniques. At high levels, carbon dioxide (CO2) is toxic and indirectly causes global warming as a precursor of ozone. Usually traffic causes emissions. Sulfur dioxide (SO2) emissions are significantly more intense during the winter season than the summer season due to combustion of fossil fuels. Winter smog is mostly found in the areas of Central, South and East South Europe. Consequently, the authorities in these areas are running the campaigns to reduce vehicle use in the center of the towns.
Disclosure of Invention
The primary objective of this invention is to reduce intensity of harmful influence of exhaust gases of IC engines in the environment. In city traffic, there is relatively a short distance between motor vehicles and that is very common at traffic lights and spots where there is a regular crossing of motor vehicles.
In these situations, the Eco filter system of an IC engine operates absorbing motor vehicle exhaust gases in front of it. Starting and stopping of the Eco filter system of an IC engine depends on a exhaust gases quantity mainly carbon dioxide (CO2). Two sensors for carbon dioxide (CO2) are placed on the frontal part of a motor vehicle. If the sensors indicate the presence of CO2, the automatic signal is transferred to the control unit that turns the electrical ventilator to function. The electrical ventilator with an absorbing branch absorbs exhaust gases of the motor vehicle ahead and forward gases to the filter. In the filter, the absorbed exhaust gases of the other motor vehicle are filtered afterwards and forwarded through an irreversible valve and a convergent nozzle to the motor vehicle exhaust pipe. The function of the irreversible valve is to stop infiltration of motor vehicle exhaust gases into the Eco filter system of IC engines. The pipe ending of the Eco filter system inserting the exhaust pipe of the motor vehicle is convergent nozzle shaped and is made to enable an axial flow of exhaust gases of the convergent nozzle. When the control unit receives a signal from the CO2 sensors, it initiates the ventilator, and simultaneously transfers the signal to the dashboard of the motor vehicle informing a driver that an eco filter system for IC engine operates. When a motor vehicle starts moving after a standstill at traffic lights, the CO2 sensors transfer a signal to the control unit that switches off the ventilator. The second signal of the control unit switches the signal light off of the motor vehicle dashboard thus informing a driver that the eco filter system of IC engine is off. The following stop and go traffic initiates switching on the eco filter system of IC engine and an exhaust gases filtration process repeats. An infra red sensor and a sound signal can be incorporated in the eco filter system of IC engine to indicate that a motor vehicle has to be moved closer to the vehicle ahead in order to absorb exhaust gases better. A line of motor vehicles that have eco filter system of IC engine perform filtration reciprocally. Any traffic standstill or a traffic accident especially in tunnels start the eco filter system of IC engine functioning thus prevent negative effects of exhaust gases on people in traffic. When operating a motor vehicle engine indoor, the eco filter system can prevent carbon dioxide poisoning of a driver. Further objectives and advantages of the invention will be described subsequently and with the application of the invention.
The invention of the eco filter system contains a ventilator, an absorbing pipe (absorbing branch), CO2 sensors, an infra red sensors, and a filter, a pressure pipe with a convergent nozzle, a control unit, a sound signal and a light indicator lamp.
An absorbing pipe or an absorbing branch is placed on the frontal face part of a motor vehicle under the light signals as a part of a bumper. The absorbing pipe outlets have an expanding with metal nets.
The ventilator is placed on the absorbing pipe thus can absorb and press exhaust gases. An electric motor of the ventilator is supplied with electric energy from an alternator of the motor vehicle. The filter for cleaning the absorbed exhaust gases is fitted in on the pressure pipe. The filter is made for this type of gas fluids - exhaust gases and can be replaced as required. The pressure pipe ending of the eco filter system for IC engine is in the exhaust pipe of the motor vehicle where absorbed and filtered exhaust gases of the other vehicle are set off. The pressure pipe ending of the eco filter system for IC engine has a convergent nozzle shape in order to make an injector effect.
On the pressure pipe ending and in front of the nozzle, there is an irreversible valve inside of a specific casing installed to prevent entering the internal motor vehicle exhaust gasses into the eco filter system of IC engine. The control unit is placed close to the ventilator and receives sensor signals, processing signals, switch on/off the ventilator and the light and sound indicators. The light and sound indicators are on the dashboard of the motor vehicle inside of the vehicle body. The light indicator lamp indicates if the eco filter system of IC engine is in function or not. The sound indicator lamp with an alarming sound indicates to drive the motor vehicle closer to the vehicle ahead it as the infra red sensor shows that the exhaust pipe of the motor vehicle ahead is out of the optimal distance.
Brief Description of Drawings
Figure 1 is a spatial view of the eco filter system of the IC engine with the component parts. Figure 2 is a specific part of a connection of the pressure pipe ending and the exhaust pipe of the IC engine.
Best Mode for Carrying Out the Invention
Here are references to the details of embodiment of the invention illustrated with the attached figures.
Referring to figures 1 and 2 show that the CO2 sensor 2 identifies the presence of CO2 and transfers the signal automatically to the electronic control unit 9 that initiates the ventilator 4 and transfers the signal to the motor vehicle dashboard with a light indicator lamp 10. The ventilator 4 absorbs exhaust gases entering into the outlets 1 of the supply pipe 3 and transport them into the filter 5 and then to the pressure pipe 6. From the pressure pipe 6, the filtered exhaust gases are getting into the exhaust pipe 7 of the IC engine through the irreversible valve 10 and the convergent nozzle 11. If identifies CO2 decrease (green traffic lights and unblocking of traffic jam), the CO2 sensor 2 transfers automatically a signal to the control unit 9 that switch the ventilator of and the light indicator lamp 10. The next traffic standstill, the CO2 sensor 2 starts the eco filter system for IC engine to function. The absorbing outlets 1 of the supply pipe 3 are under the mask (the front headlights), designed specifically to absorb better of other motor vehicle exhaust gases. Referring to the figure 2, shows that the function of the irreversible valve 10 with the nozzle 11 to prevent infiltration of self motor vehicle exhaust gases form the exhaust pipe 7 into the Eco filter system for IC engine and to make a injector effect to the absorbed exhaust gas of the other motor vehicle.
Industrial Applicability
It is possible to be constructed in different shapes and profiles adapted to the constructive characteristics of a motor vehicle. It is applicable for all motor vehicles particularly for passenger vehicles. Depending on the characteristics of a filter for cleaning exhaust gases the absorbed gas can be more or less filtered. The cleaning filter can be replaced the same as the filters inside of the IC engine once it is technically required. Instead of the ventilator the compressor can be installed inside of the eco filter system depending on the motor vehicle working conditions. The eco filter system can be used in a stationary IC engine where exhaust gases occur. The experts will easily make many modifications and transformations on the eco filter systems without disruption of essential invention's idea.
