<p>In a controller (70) for an engine (10) having a filter (45) in an exhaust passage (40) to be occasionally regenerated by raising an exhaust gas temperature, a filter regeneration means (73), if a filter trap amount is determined to be a regeneration start value (a) or more (S3) and an engine load is a predetermined load or more (S6), a main injection is made around a compression stroke top dead center and then first and second post injections are made in the following expansion stroke to perform the filter regeneration (S8). Then, the filter regeneration means (73) is configured, during filter regeneration, if a cruise control means (74) is performing a cruise control, even when an engine load becomes smaller than the predetermined load, to cause a main injection around a compression stroke top dead center and then only a first post injection to be continued in the following expansion stroke (S9), to prevent an occurrence of torque shock.</p> |
