ABSTRACT:
In a variable intake apparatus for a V-type internal combustion engine, each of plural intake pipes is separated from a surge tank by a partition wall, and communication ports, provided in the partition wall for the respective intake pipes, are opened and closed by respective variable intake valves to adjust length of intake passages. The variable intake valves in one of two parallel rows are offset from the variable intake valves in the other row. The variable intake valves are opened and closed by turning the turning shafts to which the variable intake valves are connected. Further, a synchronization mechanism synchronously turns the turning shafts (5a;5b), and is connected between the paired turning shafts. The turning motion of one turning shaft is transmitted to the other turning shaft via the synchronization mechanism, and the variable intake valves are synchronously opened and closed.
