Exhaust gas flow condition adjusting method for e.g. diesel engine, of motor vehicle, involves supplying secondary air mass flow to burner, where burner lambda value produced from injection amount and mass flow amounts to less than one

摘要

The method involves supplying injection amount of fuel into a burner (57) in a controllable or regulatable manner. Secondary air mass flow is supplied into the burner in a controllable or regulatable manner, where a burner lambda value produced from the injection amount and the secondary air mass flow amounts to less than 1. The burner is associated with an exhaust gas flow (3) of an internal combustion engine (5) of a motor vehicle (7), where the motor vehicle has an exhaust gas system (11) passing through the exhaust gas flow and downstream the internal combustion engine. An independent claim is also included for an arrangement for adjusting a condition of an exhaust gas flow of an internal combustion engine of a motor vehicle.
