    Methode of measuring engine blow-by

    dear all... thnks for advice me. some literature which I read on this page (informed by all), here is my conclusion : 1. measuring blow-by/crankcase pressure can be use the basic principle of Bernoulli equation, where this applicated to manometer system P1 + h1 = P2 + h2...(where...

    Methode of measuring engine blow-by

    ok Mr brewnog... but, why not 'A' sir? what is the reason? because, the ilustration 'A' is a simple measurement than 'B' and THE MOVEMENT OF WATER IS ONLY FROM THE 1ST WATER LEVEL TO 2ND WATER LEVEL. why the measured object is like in the picture 'B' (the parameter value is from 2nd...

    Methode of measuring engine blow-by

    ok, thnks for advice... so, which one the method to read a actual value of blow-by Mr brewnog? the 'A' or 'B' picture? and please give me a reason for each reading (mmH2O) method... note: - all this time we usually use the 'B' method we wait U'r advice again Mr... rgrds wahyudi.jr

    Methode of measuring engine blow-by

    thnks for replies Mr brewnog... if we look the blowby & crankcase pressure have a same units (mmAqua/mmH2O). the different is only on the measuring method (with pressure gauge or with plastic pipe). 1. if measure with gauge it's read a gauge pressure/not connect to atmosphere 2. if...

    Methode of measuring engine blow-by

    Mr brewnog,.. yes right, what I mean is "crankcase pressure", because in Komatsu Diesel engine, the crankcase pressure = blow-by pressure. which is method to measuring compression pressure leak for while engine, not individually. Mr thoper,... thanks for suggest, in my application both the...

    Methode of measuring engine blow-by

    dear all, some literature which I'm read, measuring blow by of engine can be execute use the pipe. not use with pressure gauge. how to measuring and calculating this if we must be use by pipe (not by pressure gauge)...? here is the ilustration...(attach) rgrds =wahyudi.jr=
