ABSTRACT:
A vehicle ejector system (100A) has an in-flow port (31a) and an out-flow port (31b) connected in the intake passage of an intake system (10) of an internal combustion engine (50), which provides communication between the atmosphere and each cylinder of the internal combustion engine, so as to include a throttle valve (13a) between the in-flow port (31a) and the out-flow port (31b). The ejector system (100A) also includes an ejector (30) that supplies negative pressure generated by the intake air passing between in-flow port (31a) and the out-flow port (31b) to a brake booster (22), a VSV (1) that allows the ejector (30) to operate and stop, and an ECU (40A) that controls the VSV (1), wherein in the combustion cycle of the internal combustion engine (50) the ECU (40A) controls the VSV (1) to operate the ejector (30).
