Title:
微粒子フィルタの再生方法およびシステム
Document Type and Number:
Japanese Patent JP2014507592
Kind Code:
A
Abstract:
The present invention relates to a method pertaining to regeneration of a particle filter (202) in a post-treatment system (200), which particle filter (202) is intended to treat an exhaust flow arising from combustion in a combustion engine (101). Regeneration involves fuel being supplied to said post-treatment system (200). The method comprises - raising a temperature of said particle filter (202) by fuel being supplied to said exhaust flow for oxidation in said post-treatment system (200), - discontinuing said supply of fuel to said exhaust flow when said particle filter temperature rises to a first level, and - resuming supply of fuel for oxidation to said post-treatment system (200) when said particle filter temperature drops to a second level which is lower than said first level. The invention relates also to a system and a vehicle.
