8.4.4. The device of neutralisation of the fulfilled gases of the diesel car
Diesel engines of the S-class are serially equipped with the catalyst and system рециркуляции the fulfilled gases. The catalyst is located in system of release of the fulfilled gases in the forward final pipeline instead of the additional muffler.
At рециркуляции the fulfilled gases their part again gets back to the combustion chamber. By means of it the combustion temperature that conducts to smaller formation окиси nitrogen (NОx) decreases. |
