Oxidation process for purifying combustion engine exhaust gas and system for supporting the performance of an oxidation catalyst |
摘要 |
<p>The ozone is: injected into a nitrogen oxides trap (NOx) trap, and into a particle filter when the temperature of the gas is lower or equal to 250[deg]C; and higher than NOx trap present in the gas. The threshold value is at 140-160[deg]C. The ratio of the ozone and the NOx is 1.3-1.7. Independent claims are also included for: (1) an assistance system; and (2) a device to carry out the above process.</p> |
