Abstract
Disclosed is an apparatus for using negative pressure energy of an engine, comprising: a first cavity (10), which first cavity (10) is in communication with the atmosphere via a first intake port (20); a second cavity (30), which second cavity (30) is in communication with the intake port of the engine (50) for supplying air to the intake port of the engine; a second intake port (40), which second intake port (40) is connected to the second cavity (30), wherein when the second intake port (40) is open, the second cavity (30) is in communication with the atmosphere for supplying the air to the intake port of the engine; and a rotating device (60), which rotating device (60) is located between the first cavity (10) and the second cavity (30), and can be rotated under the action of pressure difference between the first cavity (10) and the second cavity (30). Further disclosed is a method for using negative pressure energy of an engine. The apparatus and method for using the negative pressure energy of an engine is able to better cooperate with other parts of the vehicle while efficiently using energy.
