Intake manifold for use in four-cylinder petrol engine, has regulating element preventing reaching of blow-by gas to low pressure outlet and extending along flow of intake air flowing into manifold

摘要

The manifold (100) has a blow-by gas inlet (2) introduced through blow-by gas and a low pressure outlet (3) connected to a brake booster. A regulating element i.e. flat plate element, prevents reaching of the blow-by gas to the low pressure outlet. The regulating element extends along the flow of intake air flowing into the manifold. The low pressure outlet downstream of the blow-by gas inlet is provided with respect to the flow of intake air. Another regulating element i.e. plate element, is provided between the low pressure outlet and the former regulating element.
