  • Figure 9 shows the difference between the measurements of the Pre and Post probes, i.e the amount of C0 2 absorbed, vs time.
  • the sudden spikes in the said figure correlate with the engine's rpms and hence the temperature of the exhaust gases have been increased.
  • the first spike appears when temperature is increased from 85 degrees Celsius to 155 degrees Celsius.
  • the second spike appears at an increase from 155 to 185. Because this reversed the process and resulted in C0 2 being emitted rather than released, the temperature was reduced once more to 155 degrees Celsius.
  • the cartridge can successfully reduce C0 2 emissions from vehicles.
  • a coiled pipe which alternates in diameter with some lengths of it being narrow and others being wide can be used for better efficiency.
  • the wider stretches of pipe will further slow down the exhaust gases and allow the device to become more efficient if the cartridges are placed in these sections.
  • the narrow sections of the pipe will speed up the exhaust gases during the time that they are travelling between cartridges and help counteract the increase in back pressure.
  • Figure 10 shows the results on a graph of the experiment conducted in Example 6.
  • the amount of C0 2 absorbed is shown in the y axis in hundreds of parts per million.
  • the graph of Figure 10 depicts the difference between pre and post cartridge amount of CO 2 absorbed vs time. The fluctuations are accounted for by the fact that the flow rate and temperature in the exhaust fluctuated a little with time.
  • the frequency of the readings and the frequency of the cycle of the engine also collude to form the waveform- like graph as seen in Figure 10.
  • Back pressure At idling, back pressure is 60 bars and once the engine is started, back pressure escalated to about 83 bars. This is only a 23% increase in back pressure as compared to a 66.67% increase with the single mesh cartridge design of Example 5. This is the most significant difference in result that the new design does reduce back pressure. Using more meshes would further reduce the back pressure generated by the scrubber and allow the coiled pipe to be used in such a way as not to significantly affect the vehicles fuel efficiency.
  • the cartridge configuration of the invention does not hinder the absorption of C0 2 and is at least 2-3% more efficient. The efficiency can therefore be further enhanced though other embodiments of the invention by changing several other factors:
  • the number of meshes can be increased feasibly, depending on granule size. For example 1 mesh per cm of pipe, resulting in 10 meshes in 10 centimeters of pipe.
