【発明の名称】クランクケースベンチレーション装置
Document Type and Number:
Japanese Patent JP2956763
Kind Code:
B2
Abstract:
A closed crankcase ventilation system for a turbocharger internal combustion engine is proposed which uses differential pressure between the turbo compressor inlet and the crankcase to force blow-by gases through a separation device. The zone of low pressure of the turbo compressor inlet is located at the innermost diameter of the compressor inlet shroud. The difference between the pressure in the compressor inlet and the crankcase creates a vacuum which pulls gas from the crankcase into the ventilation system. The ventilation system includes a high restriction separator (25) for removing oil from the blow-by gases. A control valve (24) bypasses the separation device when insufficient pressure differential exists to drive the separator.
