A PRECISION PRESSURE-SOURCE SYSTEM FOR EFI-CONTROL-UNIT CALIBRATION AND TEST

Simulating manifold absolute pressure for the calibration and test of domestic Electronic Fuel Injection (EFI) controls demanded an absolute-pressure-source-system stability, accuracy, and speed of response not previously required for automotive-component manufacture. A 36-point pressure source having a root-mean square stability of plus minus 0.002 pound per square inch (plus minus 13 pascals) absolute, an accuracy of better than plus minus 0.002 pound per square inch (plus minus 13 pascals) absolute, and a response time of 500 milliseconds into a 1-cubic-inch (16-cubic centimeter) switched volume was developed to meet this need.
