Abstract
A test equipment for testing a fuel pump of the kind intended to supply fuel to a multi-cylinder engine comprises a chamber into which fuel from the outlets of the pump under test can be directed through nozzles respectively. A restricted outlet is provided from the chamber and a pressure transducer is provided to provide a signal indicative of the pressure in the chamber. The equipment also includes a display apparatus which receives the signal from the transducer and an encoder is provided which supplies a signal to the display apparatus indicative of the position of the drive shaft of the pump.
Claims6
A test equipment for use when testing a fuel injection pump of the kind intended to supply fuel to a multicylinder internal combustion engine, the test equipment comprising means defining a chamber, a plurality of nozzles having inlets for connection to the outlets of the injection pump respectively, said nozzles being positioned to direct liquid into said chamber, a restricted outlet from said chamber, a pressure transducer for providing a signal indicative of the pressure variation in said chamber as fuel is directed into the chamber from the nozzles in turn, and a display apparatus which receives the signal from said transducer and displays the pressure variations in said chamber.
