Abstract:
A filtering means regenerating system for a diesel engine wherein filtering means is provided in an exhaust gas passage of said engine to oxidize NO in exhaust gas of said engine into NO2, and to collect particulates in said exhaust gas passing through said exhaust gas passage to thereby oxidize said particulates by means of said NO2 and remove the same at a temperature higher than a predetermined exhaust gas temperature, comprising:(1) a variable stator blade provided in a turbocharger for supercharging intake air in an intake air passage of said engine by means of energy of said exhaust gas to regulate the amount of said intake air supercharged into said intake air passage, (2) deposit detecting means for detecting the deposit of particulates deposited on said filtering means; and (3) a controller for controlling said variable stator blade based on the detection output of said deposit detecting means.
