Detailed description of the embodiments:
[0005] FIG. 1 illustrates an auxiliary air delivery system 100 for delivering pressurized air to an inlet manifold 110 of an internal combustion engine 120. The auxiliary air delivery system 100 comprises a piston chamber 130 that contains a first piston 140 that is positioned within the piston chamber 130. A lever 150 is mechanically coupled to the first piston 140 at its one end 160 and adapted to be actuated by means of a force applied to the lever 150 at its opposite second end 170. A storage chamber 180 is in flow communication with the piston chamber 130, wherein the storage chamber 180 comprises a second piston 190 that is positioned within the storage chamber 180 and adapted to be displaced within the storage chamber 180 to facilitate delivering pressurized air from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120. A spring member 200 is secured between an end of the second piston 190 and an end of the storage chamber 180. The spring member 200 is adapted to be compressed when the second piston 190 positioned within the storage chamber 180 is displaced within the storage chamber 180. The spring member 200 is adapted to apply a restoring force on the end of the second piston 190 to facilitate displacing the second piston 190 towards the first piston 140.

[0006] FIG. 1 illustrates an auxiliary air delivery system 100 for delivering pressurized air to an inlet manifold 110 of an internal combustion engine 120. The auxiliary air delivery system 100 comprises a piston chamber 130. The piston chamber 130 contains a first piston 140 that is positioned within the piston chamber 130 and is adapted to reciprocate within the piston chamber 130 to facilitate delivering pressurized air from the piston chamber 130 towards a storage chamber 180 and receive air via suction means from the storage chamber 180 to the piston chamber 130 respectively. In an exemplary embodiment, a lever 150 is mechanically coupled to the first piston 140 at its first end 160 via fastening means. The lever 150 that is mechanically coupled to the first piston 140 at its first end 160 via fastening means is adapted to be actuated by means of a force that is applied to the lever 150 at its opposite second end 170. A pivot 250 is defined between the first end 160 of the lever 150 and an opposite second end 170 of the lever 150 and is adapted to rotate the lever 150 about an axis that is perpendicular to a horizontal axis and a vertical axis. The rotation of the lever 150 about an axis that is perpendicular to the horizontal axis and the vertical axis causes the first piston 140 that is positioned within the piston chamber 130 and secured to the first end 160 of the lever 150 to reciprocate within the piston chamber 130 to facilitate delivering pressurized air from the piston chamber 130 to the storage chamber 180 and receive air via suction means from the storage chamber 180 to the piston chamber 130 respectively.

[0007] In an exemplary embodiment, thestorage chamber 180 is secured to the piston chamber 130 and is in flow communication with the piston chamber 130. The storage chamber 180 is a rectangularly shaped chamber that comprises a second piston 190 that is positioned within the storage chamber 180 and is adapted to be displaced within the storage chamber 180. More specifically, the displacement of the second piston 190 within the storage chamber 180 facilitates delivering pressurized air from the storage chamber 180 to an inlet manifold 110 of the internal combustion engine 120. A spring member 200 is secured between an end of the second piston 190 and an end of the storage chamber 180. The spring member 200 is adapted to be compressed when the second piston 190 that is positioned within the storage chamber 180 is displaced within the storage chamber 180. More specifically, when the second piston 190 is displaced towards the inlet manifold 110 of the internal combustion engine 120, the second piston 190 is displaced against the spring member 200 and compresses the spring member 200 against a resistive force of the spring member 200. When the second piston 190 is displaced towards the piston chamber 130, the second piston 190 is displaced away from the spring member 200 and elongates the spring member 200 due to a restoring force that is applied by the spring member 200 on the second piston 190. The spring member 200 is adapted to apply a restoring force on the end of the second piston 190 to facilitate displacing the second piston 190 towards the piston chamber 130.

[0008] In an exemplary embodiment, the storage chamber 180 that is in flow communication with the piston chamber 130 comprises a first spring loaded ball valve 210. More specifically, the first spring loaded ball valve 210 comprises a V-shaped valve seat 211 with a ball 212 positioned against the V-shaped valve seat 211 to facilitate closing the first spring loaded ball valve 210. The spring member 220 is positioned against the ball 212 that is positioned against the V-shaped valve seat 211 to facilitate biasing the ball 212 against the V-shaped valve seat 211. When the ball 212 of the first spring loaded ball valve 210 is biased against the V-shaped valve seat 211, the first spring loaded ball valve 210 is closed thereby preventing the flow of fuel from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120. When the ball 212 of the first spring loaded ball valve 210 is displaced away from the V-shaped valve seat 211, the first spring loaded ball valve 210 is opened, thereby allowing the flow of fuel from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120.

[0009] In an exemplary embodiment, the ball 212 of the first spring loaded ball valve 210 is adapted to be displaced against a resistive force of its spring member 220 when the second piston 190 that is positioned within the storage chamber 180 is displaced within the storage chamber 180 against a resistive force of the spring member 200. The displacement of the ball 212 of the first spring loaded ball valve 210 against a resistive force of its spring member 220 facilitates delivering pressurized air from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120 via the first spring loaded ball valve 210. In an exemplary embodiment, the storage chamber 180 that is in flow communication with the piston chamber 130 comprises at least one second spring loaded ball valve 230 that is positioned within the storage chamber 180. A ball 231 of the second spring loaded ball valve 230 is adapted to be displaced against a resistive force of its spring member 240 when the second piston 190 that is positioned within the storage chamber 180 is displaced within the storage chamber 180 towards the first piston 140 due to a restoring force of the spring member 200. The displacement of the ball 231 of the second spring loaded ball valve 230 due to a resistive force of its spring member 240 facilitates delivering air from an external environment to the storage chamber 180 via the second spring loaded ball valve 230 when the second piston 190 that is positioned within the storage chamber 180 is displaced within the storage chamber 180 towards the piston chamber 130. The displacement of the second piston 190 within the storage chamber 180 towards the piston chamber 130 admits air at low pressure from the external environment to the storage chamber 180 for pressurization and delivery to the inlet manifold 110 of the internal combustion engine 120 in the subsequent cycle.

[0010] In an exemplary embodiment, a diameter of the piston chamber 130 is smaller than a diameter of the storage chamber 180. Therefore, a diameter of the first piston 140 that is positioned within the piston chamber 130 is smaller than the diameter of the storage chamber 180 that facilitates transmitting a force from the piston chamber 130 that is transmitted to the storage chamber 180 and is applied on an end face of the second piston 190. The force that is applied on the end face of the second piston 190 causes the second piston 190 to translate towards the inlet manifold 110 of the internal combustion engine 120 against the resistive force of the spring member 200. In addition, when a force is applied to the lever 150 at its opposite second end 170, the lever 150 is rotated in the anti-clockwise direction that facilitates translating the first piston 140 towards the storage chamber 180. The translation of the first piston 140 towards the storage chamber 180 causes a pressure to be exerted from the piston chamber 130 on the second piston 190 that is positioned within the storage chamber 180. The pressure that is exerted from the piston chamber 130 on the second piston 190 that is positioned within the storage chamber 180 causes the second piston 190 to be displaced within the storage chamber 180 away from the piston chamber 130 and against a resistive force of its spring member 200. The displacement of the second piston 190 within the storage chamber 180 and away from the first piston 140 facilitates delivering pressurized air from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120 via the first spring loaded ball valve 210. Once the pressurized air is delivered from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120 and air injection to the inlet manifold 110 of the internal combustion engine 120 from the storage chamber 180 is complete, the second piston 190 is translated towards the piston chamber 130. Therein, the first piston 140 translates away from the storage chamber 180 and towards the piston chamber 130 that causes a suction force to be exerted on the second piston 190 that is positioned within the storage chamber 180 from the piston chamber 130. The suction force that is exerted on the second piston 190 that is positioned within the storage chamber 180 from the piston chamber 130 causes the second piston 190 to be displaced within the storage chamber 180 towards the first piston 140. In addition, the second piston 190 is displaced within the storage chamber 180 towards the first piston 140 due to a restoring force of its spring member 200. The displacement of the second piston 190 within the storage chamber 180 towards the first piston 140 due to the restoring force of the spring member 200 facilitates channeling air from the external environment to the storage chamber 180 via the at least one second spring loaded ball valve 230.

[0011] A working of the auxiliary air delivery system 100 for delivering pressurized air to the inlet manifold 110 of the internal combustion engine 120 is described as an example. When compressed air is delivered from a compressor of a turbocharger to the inlet manifold 110 of the internal combustion engine 120, it is required to augment the air that is delivered from the compressor of the turbocharger by supplying additional air from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120 for effective combustion. When a force is applied at the opposite second end 170 of the control lever 150 by means of a force applied on an accelerator pedal, the control lever 150 is rotated in the anti-clockwise direction. The rotation of the control lever 150 in the anti-clockwise direction causes the first piston 140 that is secured to the first end 160 of the control lever 150 to be displaced towards the storage chamber 180. The displacement of the first piston 140 that is secured to the first end 160 of the control lever 150 causes a pressure to be exerted in the storage chamber 180 that causes the second piston 190 positioned within the storage chamber 180 to be translated towards the inlet manifold 110 of the internal combustion engine 120 against the resistive force of the spring member 200. The displacement of the second piston 190 that is positioned within the storage chamber 180 within the storage chamber 180 against the resistive force of the spring member 200 causes the pressurized air that is within the storage chamber 180 to be delivered via the first spring loaded ball valve 210 against the resistive force of its spring member 220 to the inlet manifold 110 of the internal combustion engine 120. After air is completely delivered from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120 via the first spring loaded ball valve 210, the compressor of the turbocharger continues delivering the required quantity of air to the inlet manifold 110 of the internal combustion engine 120 without the requirement of additional air that is delivered from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120.

[0012] Thereafter, once air is completely delivered from the storage chamber 180 to the inlet manifold 110 of the internal combustion engine 120 via the first spring loaded ball valve 210, the second piston 190 is displaced towards the piston chamber 130 due to the suction force that is created by the first piston 140 in the piston chamber 130 coupled with the restoring force that is exerted by the spring member 200 on the second piston 190 that is positioned within the storage chamber 180. When the second piston 190 is displaced towards the piston chamber 130, the suction force that is created within the storage chamber 180 causes the ball 231 of the at least one second spring loaded ball valve 230 to be displaced against the resistive force of its spring member 240. The displacement of the at least one second spring loaded ball valve 230 against the resistive force of its spring member 240 causes low pressure air to be channeled from the external environment into the storage chamber 180 until the second piston 190 stops being displaced towards the piston chamber 130. Thereafter, the next cycle begins with the second piston 190 being displaced towards the inlet manifold 110 of the internal combustion engine 120 against the resistive force of the spring member 200 due to the compressive force imposed by the air in the piston chamber 130 on the second piston 190.

Many such embodiments and other modifications and changes in the embodiment explained in the description are envisaged. The scope of the invention is only limited by the scope of the claims.
