DESC:TECHNICAL FIELD
The present disclosure relates to the field of a dust ejection system for vehicle engines.

BACKGROUND
A critical factor for the efficient operation of a vehicle engine is the introduction of clean air inside the combustion chamber of the vehicle engine. In order to ensure supply of clean air into the combustion chamber, manufacturers fit the vehicle engines with air filters. The primary function of the air filter is to filter the incoming air while storing the collected pollutants and other dust particles in a dust bowl. The air containing pollutants, dust particles, carbon and smoke and other particulate matter such as husk resultant of farming activities are collected in the dust bowl. The dust bowl when filled with particulate matter requires frequent cleaning and replacement of the filter. The clogged filters are also responsible for a pressure drop across the air cleaner and results in more power requirement for introducing clean air inside the engine. Some of the problems associated with the existing air cleaning systems are frequent replacement of the filters or the replacement of oil which proves to be cumbersome and results in increased operating and maintenance cost. Another problem with regards to the dust bowl design includes increase in time required for exiting the dust particles.

Hence, there is felt a need for a dust ejection system for vehicle engines which will overcome at least some of the abovementioned problems. Still further, there is a need for a dust ejection system that is simple in construction that automatically removes dust collected in the filter regularly without requiring any human intervention.

It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the embodiments as described herein.

The key disadvantages associated with the traditional systems of dust handling for vehicles include frequent removal and cleaning of the dust bowl, requirement for frequent oil change which results in increased running costs, loss of productive time and increased fatigue to the operator. Hence there is a need for a solution which fully or at least partially alleviates the disadvantages associated with the traditional method of dust handling for the vehicles.

Referring to the accompanying drawings, Figure 1 illustrates a line diagram depicting various elements of a traditional air intake system in accordance with the prior art. In an air intake system, air enters the intake manifold which is subject to pre cleaning in a pre-cleaning filter 108. It is then cleaned using an air cleaner 102 and then transferred to the engine (not shown) via a hose 104 and a duct 106. The dirt and the dust removed from the air by the air cleaner 102 is stored in a dust bowl 140 which is subject to constant removal and cleaning. The constant removal and cleaning is cumbersome as sometime takes more time due to the design of dust bowls.

To limit such drawbacks of the conventional air cleaning systems, the system of the present disclosure envisages an automatic dust ejection mechanism. Referring to the accompanying drawings, Figure 2 illustrates a line diagram depicting a dust ejection system 100 in accordance with an embodiment of the present disclosure. The dust ejection system 100 of the present disclosure automatically removes dust collected in the filter regularly without requiring any human intervention. The dust ejection system 100, along with the traditional components like duct 106, hose 104, air cleaner 102 and dust bowl 140 of a traditional air intake system (similar to the system in Figure 1), includes a venturi 110 connected to the dust bowl 140 through a valve conduit 134, a non-return valve 112 and a conduit 114.
Figure 5 of the accompanying drawings illustrates a schematic representation of a dust ejection system 100 in accordance with an embodiment of the present disclosure. The dust ejection system 100 is functionally coupled to a radiator 116 having a fan 118 attached to it. The function of the fan 118 is to suck the air around the radiator 116 and throw the air outwardly. This forced air is partially allowed to enter the venturi 110. Figure 6 of the accompanying drawings illustrates a schematic representation of the venturi 110. The venturi 110 primarily includes an inlet 122, middle section 130, an outlet 124 and a venturi hose 132 attached to the middle section 130. This venturi 110 is so positioned in the dust ejection system 100 that the fan 118 drawing air over the radiator 116 blows air into the inlet 122 of the venturi 110. More specifically, the fan 118 is disposed between the radiator 116 and the venturi 110. As the high pressure air enters the venturi 110 through the inlet 122, it loses pressure in the middle section 130 due to the venturi 110 configuration and the velocity of the air increases as it passes through the middle section 130. This particularly leads to the conversion of the pressure into kinetic energy. The venturi hose 132 attached to the middle section 130 is further attached to a conduit 114, wherein other end of the conduit 114 is connected to a non-return valve 112. Figure 7 of the accompanying drawings illustrates a sectional view of a non-return valve 112 which is coupled to the venturi 110. When the air is directed at a high velocity from the venturi 110 to the non-return valve 112, the non-return valve 112, in one embodiment, allows air to enter the valve inlet 126 and exit through the valve outlet 128. But, the non-return valve 112 does not allow the flow in the reverse direction. According to one embodiment, the non-return valve 112 includes other sub parts such as a rubber ring 136 and a metal flap 138. When the mixture of dust/ dirt particles carried with the air enters the non-return valve 112 through the valve inlet 126, the metal flap 138 seals the non-return valve 112 using the rubber ring 136. In one embodiment a hinged support is provided on one side of the metal flap 138. When the engine is stopped, the metal flap 138 is closed. When the engine is started, the metal flap 138 is opened by the air action generated by the fan 118. The main advantage of the current embodiment of the non-return valve 112 includes its automatic operation. Another end of the non-return valve 112 is connected to a valve conduit 134 which allows connection of the non-return valve 112 to the air cleaner placed inside a housing 120. With such configuration the particulate matter (dust/dirt particles) collected in the dust bowl placed in the housing 120, is sucked to the middle section 130 of the venturi 110 due to the low pressure developed at the middle section 130. The conduit 114 and the valve conduit 134 draw the particulate matter collected in the dust bowl and facilitate evacuation of the particulate matter from the dust bowl through the outlet 124 of the venturi 110 in a single direction, thereby resulting in regular and automated cleaning of the filter. Accordingly, with such configuration the need for regular maintenance and cleaning of the air cleaner and the dust bowl is eliminated, thereby reducing maintenance and human intervention.

Such a system 100 as specified in the present disclosure avoids the need for frequent removal and cleaning of the dust bowl and automates the removal and disposal of the dirt/ dust particles. It saves on frequent oil changes and saves the productive time of the operator/ driver.
Figures 3a and 4a of the accompanying drawings, illustrate respectively the right and left side view of the traditional air inlet system which includes a traditional air cleaner and dust bowl placed in a housing 120. Figures 3b and 4b of the accompanying drawings respectively illustrate the right and left hand views of the dust ejection system of the present disclosure wherein the dust ejection system includes a housing 120 connected to the venturi 110 through the valve conduit 134, non-return valve 112 and the conduit 114.

Figure 8a of the accompanying drawings illustrates a front view of the traditional air intake system having a housing 120 including a traditional dust bowl 140’. The traditional dust bowl 140’ faces problems primarily including clogging of the drain pipe 144. This leads to saturation of the dust and outside pollutants on the filter affecting filter life and causes a pressure drop across the air intake affecting engine performance. The traditional dust bowl 140’ also faces a problem termed as a rotating cloud wherein the dust particles keep rotating inside the bowl and take relatively longer time to exit through the drain pipe 144. Figure 9a illustrates a tilted view of the traditional dust bowl 140’. As illustrated in the Figure 9a, the dust cloud keeps rotating for a long period prior to exiting through the drain pipe 144. In order to break this rotation the system of the present disclosure envisages a plurality of deflectors to be fitted in the dust bowl.

Figure 8b illustrates a front view of an air intake system having a housing 120 and a modified dust bowl 140 in accordance with one embodiment of the present disclosure. The figure further illustrates the placement of deflectors 142 to break rotating dust clouds. Figure 9b illustrates a tilted view of the modified dust bowl 140 with deflectors 142 in accordance with one embodiment of the present disclosure. In accordance with one embodiment, the deflectors 142 are L shaped elongated objects fixed radially along the bottom surface of the dust bowl 140. The path of the rotating dust cloud obstructed by these deflectors 142 breaks the travelling velocity of the rotating dust cloud and forces the dust particles to move along the length of the elongated structures of the deflectors 142 and thus exit the dust bowl 140 through the drain pipe 144. Installation of these deflectors 142 breaks the swirling motion of the dust particles and takes away the momentum of the particles to avoid formation of a rotating cloud. Upon hitting the deflector plates, the particles fall down in the drain pipe 144 at the bottom relatively easily. This improves evacuation of the dust particles.
