Abstract
The present invention relates to an internal combustion engine () of the Otto type, comprising an induction pipe () in conjunction with the engine's () cylinders, a brake servo unit (), a flow connection () for evacuating air from the brake servo unit () to the induction pipe () for the purpose of building up a vacuum inside the brake servo unit (), in conjunction with which a Venturi unit () is arranged in the flow connection () to assist with the building up of the aforementioned vacuum. The internal combustion engine is characterized in that the flow connection () comprises a bypass line () having a lower flow resistance than the Venturi unit (), the bypass line () being intended to connect the evacuated air past the Venturi unit () in the event of a transient vacuum in the induction pipe ().
