METHOD AND SYSTEM PERTAINING TO MONITORING PARTICLE EMISSIONS IN COMBUSTION ENGINE EXHAUSTS

A method for determining particle emissions from a combustion engine: a post-treatment system including at least one particle filter post-treats an exhaust flow from combustion in the engine. A PM (particulate matter) sensor situated upstream of the particle filter determines, at a location upstream...

More Information
Summary:A method for determining particle emissions from a combustion engine: a post-treatment system including at least one particle filter post-treats an exhaust flow from combustion in the engine. A PM (particulate matter) sensor situated upstream of the particle filter determines, at a location upstream of the particle filter, a first particle content of the exhaust flow arising from the engine and uses the determined first particle content as a basis for determining whether the particle content of the exhaust flow downstream of the particle filter fulfils a first condition. Also, a system and a vehicle for performing the method are disclosed.
