Patent DE-19952830-A1 (DE)
Inventor: BLUHM KURT
IPC: F02D41/40
Filed: 1999-11-02
Abstract: The invention relates to a method for the post-treatment of exhaust gases by subsequent injection of fuel in a diesel-type internal combustion engine that is provided with a pre-catalyst and a particle filter. According to this method, the subsequent injection NE proceeds depending on the temperature in the pre-catalyst zone TKat and the charging state of the particle filter. The inventive method functions especially effective in the short distance operation of diesel-type internal combustion engines which so far has been critical, and will meet even the strict requirements of exhaust gas regulations yet to come.
