Mecelec Design has designed and built a machine for testing high pressure fuel injectors. This machine uses extremely high pressures during testing, which are required for the correct operation of the injectors. The machine also supplies lower pressure test fluid and lubricating oil to the high pressure pump itself. The machine also allows identification of the part on test and the detailed results of the test to be passed back to a main factory network. The machine monitors a wide range of meters and probes to monitor numerous aspects of the machine, including oil flow rates, temperatures of various components and pressures.
