Abstract
A method and apparatus for determining a characteristic of an injector are set forth. In one example, a compressed gas is applied to the inlet chamber of the injector while the spoolvalve is closed until the pressure of the compressed gas in the inlet chamber reaches a predetermined pressure. A change in pressure of the compressed gas in the inlet chamber is measured over time while the spool valve is closed. The pressure change measurement corresponds to the characteristic of the injector that is to be determined.
