摘要：An apparatus and a method for testing the integrity of fuel or gas caps forleaks is disclosed. A microprocessor controls the pressurization of an air reservoir whichselectively allows air to pass to either the combination of the fuel cap under test and a
reference orifice or to only the reference orifice and computes the ratio of the timerequired for the pressure within the air reservoir to drop between predeterminedpressure levels for the combination of the fuel cap under test and the reference orificeversus only the reference orifice and compares same against a standard ratio todetermine whether the leakage rate through the fuel cap meets an acceptable limit.
