| 摘要 |
The present invention relates to a method for determination of particle emissions pertaining to a combustion engine, such that a post-treatment system comprising at least one particle filter is provided to post-treat an exhaust flow arising from combustion in said engine. The method comprises - using a PM sensor situated upstream of said particle filter to determine, at a location upstream of said particle filter, a first particle content of said exhaust flow arising from said engine and - using said first particle content determined as a basis for determining whether the particle content of said exhaust flow downstream of said particle filter fulfils a first condition. The invention relates also to a system and a vehicle. |
