Abstract
A method and an apparatus for measuring a flow rate of a gas such as a blow by gas in a reciprocating internal combustion engine in which condensable components and mists are contained are disclosed. The method for measuring the flow rate of the gas is characterized in that only after the condensable components and the mists contained in the gas to be measured have been removed from the gas the flow rate of the gas is measured. The apparatus for carrying out the method comprises a condensable components/mists removing portion, a gas flow rate measuring portion and a piping means to connect the above two portions, whereby the condensable components/mists removing portion is constituted by a column-like vessel into which the gas is introduced at its lower portion, and the gas has the mists removed by impinging upon the gas deflecting means provided within the vessel, the gas having the condensable components removed by cooling the gas to a temperature close to the atmospheric temperature. The gas thus having the condensable components and mists contained therein removed is fed to the gas flow rate measuring portion through the piping portion to have its flow rate measured by a gas flow meter, in particular by a thermal micro-tube type gas flow meter.
