EUI Injector Flush Bench

Description

This EUI Injector Flush Bench was designed to flush debris and old fuel from warranty returned fuel injectors so that they won’t contaminate the test machines when they are evaluated for failure.

The EUI Injector Flush Bench also flushes out diesel fuel injectors that are returned under warranty to the OEM. Typically these returned injectors are filled with diesel fuel and have soot and contaminants in them from the engine environment. Running these on a production test bench without flushing would contaminate the calibration fluid in the tanks and require changing out the fluid afterwards – a risky proposition on a production line.

Particle counters on the return and output from the EUI injector continuously monitors the particle count in the flushing fluid so that the machine “knows” when and if the EUI injector has been thoroughly flushed. A waste tank in the system collects initial debris and diesel fuel that wouldn’t be able to to be filtered out of the flushing fluid.
