Purifying IC engine exhaust gas comprises taking measures to increase exhaust gas temperature with introduction of event which can be canceled after combustion

摘要

Purifying internal combustion (IC) engine exhaust gas comprises taking measures to increase the exhaust gas temperature with the introduction of an event which can be canceled after combustion of at least one part of the injected particles. An Independent claim is also included for a device for carrying out the process comprising an IC engine (1); an air suction line (2) with an adjustable choke (13) extending into the engine; an injection device with valves for the direct injection into the cylinder of the engine; an exhaust gas line (3) extending from the engine and containing a particle filter (7); and a device (25) for increasing the exhaust gas to a temperature at which the particles of the filter combust on exceeding a determined exhaust gas pressure, after a model-supported enquiry, at a critical temperature in the exhaust gas, in determined time intervals or sporadically.
