ABSTRACT:
An internal combustion engine for a vehicle comprises a pair of intake collectors (3A,3B) and a communicating pipe (13) connecting the pair of intake collectors (3A,3B). A negative pressure supply port (15) supplying intake negative pressure of the internal combustion engine to a brake booster is provided at an end of the communicating pipe (13). By providing an air amount deviation compensating arrangement which compensates for a deviation in the amounts of air flowing into the pair of intake collectors (3A,3B) from the brake booster when braking of the vehicle is released, the amounts of air supplied to the internal combustion engine from the pair of the intake collectors (3A,3B) are equalized.
