Abstract:
1. Combustion engine, comprising: an intake system having a throttle valve controlling an air flow to the combustion engine, a brake booster being in fluid communication with the intake system, downstream the throttle valve, via an evacuation duct, for evacuation of air from the brake booster to the intake system, a crankcase being in fluid communication with the intake system, downstream the throttle valve, via a low load duct for conducting crankcase gases to the intake system, a venturi tube forming part of the low load duct, wherein the venturi tube comprises a venturi tube portion forming a flow resistance within the low load duct through which the crankcase gases have to pass, wherein the evacuation duct is also fluidly connected to the venturi tube portion, via a connection duct, for further evacuation of air from the brake booster to the intake system.
