METHOD AND SYSTEM FOR DIAGNOSIS OF A COMBUSTION ENGINE

The present invention relates to a method for diagnosis of a combustion engine, such that a post-treatment system (200) comprising at least one particle filter (202) is provided to post-treat an exhaust flow arising from combustion in said combustion engine (101), which method comprises using a PM s...

More Information
Summary:The present invention relates to a method for diagnosis of a combustion engine, such that a post-treatment system (200) comprising at least one particle filter (202) is provided to post-treat an exhaust flow arising from combustion in said combustion engine (101), which method comprises using a PM sensor (222) situated upstream of said particle filter (202) to determine, at a location upstream of said filter (202), a first particle content (P1) of said exhaust flow arising from said engine (101), and using said first particle content (Rho1) determined as a basis for determining whether said engine (101) is malfunctioning. The invention relates also to a system and a vehicle (100).
