Leak Test Application from TQC Vauxhall V6 Inlet Manifold Leak Test Machine The manifold leak test station consists of a test unit located in the V6 engine assembly area, and is a self contained, free standing unit consisting of an aluminium frame on which is mounted a loading fixture, an operator control closure, an electrical closure, a pneumatic air compressor and a hydraulic power pack. The test component is manually loaded to a retractable drawer, at which time an operator is required to connect the wiring harness to the connector provided and also connect the fuel rail connectors. At this point the drawer is closed and the sealing begins. The instrument controls the complete leak test cycle, including fill, stabilisation and measurement, basic operating principle is that of measuring pressure decay in the test volume as compared with the pressure in a reference volume, both having stabilised to the same pressure before starting the measurement. Test pressures are controlled by an E-P regulator and are set to nominally 1.5 bar for the manifold, 4.0 bar for the fuel rail and 3.4 bar for the regulator. Test parameters (time, alarm limits, etc) are programmable via the key pad on each instrument. Results are indicated in terms of leakage rates (converted to cu.mm/sec) on each instrument when a positive leakage is measured.
The Facility is designed to carry out 4 automatic air decay tests on a manually loaded assembly, the tests are performed on the following :
