Abstract

In a closed crankcase ventilation system, crankcase gases are allowed to flow through a venturi (10) which includes high pressure and low pressure taps (24 and 28). The high and low pressure taps (24) and (28) are coupled to a differential pressure transducer (30) which produces an output that is proportional to the volumetric flow of crankcase gases through the venturi (10). The use of a venturi (10) in conjunction with a differential pressure sensor (30) offers a low resistance path for the flow of crankcase gases and allows continuous monitoring of blow-by without exceeding the operating pressure limitations of various oil seals. Such a sensor (30) is particularly suited for closed crankcase ventilation (ccv) systems, as it doesn't require venting of crankcase gases to the atmosphere, but works well in open crankcase ventilation systems also.
