Document Type and Number:
Japanese Patent JPS59500015
Kind Code:
A
Abstract:
A method and apparatus for measuring the volume of a chamber in a part, such as the combustion chamber of an internal combustion engine cylinder head by, comparing the test chamber with a reference chamber of known volume, wherein the reference chamber is exposed to the part containing the test chamber so that ambient variables are minimized, and accurately controlled quantities of a gas are injected into each chamber and the difference in pressures in the chambers read as a function of test chamber volume, and thereafter the rate of change of pressure differences in the chambers is read as a function of chamber leakage and the volume measurement discarded if the rate of change exceeds a determined value.
