MOTORAUSPUFFKONTROLLEINRICHTUNG.

摘要

This invention relates to an exhaust control device of an engine (10) having at least three exhaust pipes (16a-d) receiving exhaust control valves (36a-d), therein to change the area of exhaust flow path of each exhaust pipe (16a-d). One valve shaft (40a) common to a group of exhaust control valves (36a, 36d) and one valve shaft (40b) common to another group of exhaust control valves (36b, 36c) are disposed non-coaxially and nearly parallel with each other. A rotation input member (42) is mounted on one end of said one valve shaft (40a) and a rotation transmission mechanism (A) which interlinks both valve shafts (40a, 40b) is provided on the same side at the end of both of said valve shafts (40a, 40b) (Figure 6).
