Abstract:
1. An exhaust gas purification device of an engine for a vehicle, comprising; a filter member disposed in an exhaust passage of the engine to trap exhaust particulates in an exhaust gas; a temperature detecting device operative to detect a temperature of said filter member; a manual regeneration switch operative by a passenger to commence regeneration of said filter member; a shift range position detecting sensor operative to detect a shift range position of a shift device of the vehicle; an engine speed adjusting device operative to adjust an engine speed; and a control unit operative to receive respective signals from said temperature detecting device, said manual regeneration switch and said shift range position detecting sensor, and output a control signal to said engine speed adjusting device, wherein said control unit is configured so as to output the control signal to adjust the engine speed in such manner that, (a) when said manual regeneration switch is operated and it is determined that the vehicle is in a stop state, the engine speed is adjusted to a first target speed which is higher than a specified normal speed and capable of substantially regenerating said filter member, (b) when said manual regeneration switch is operated and it is determined that a state of the vehicle changes from the stop state to a driving state, and
