Simple injection-nozzle testing – EPS 100

EPS 100 – Injection-nozzle testing made easy

EPS 100
The Bosch injection-nozzle tester has a wide range of applications: • Testing and adjustment ofinjection-nozzle opening pressure • Assessment of the injection spray regarding shape and atomization (injection-spray image) • Checking for leaks in injection nozzles, and checking the chatterproperties on two-stage nozzle holders, stage holders and UI/UP applications Compared to the predecessor model EFEP 60H, due to better dial reading accuracy (1 bar), and improved manometer measuringaccuracy, the possible overall measuring inaccuracy has improved on the EPS 100 from +/-4 bar to +/-2.4 bar. This allows the smallest leaks to be analyzed and excluded. Possible vibration of the engine inidling can thus be avoided. Design improvements have resulted in the inner leakage of the EPS 100 being considerably lower than that of the EFEP 60H. This has the advantage that within the framework ofleakage testing on two-stage nozzle holders and unit injectors etc., the generated pressure does not drop.

Extraction Unit EPS 738
This extraction unit is used in combination with nozzle testersto keep environmental damage down to a minimum, and to prevent health hazards, when testing injection nozzles in the workshop. The unit draws in the oil mist which is generated when testing injectionnozzles. Principle of functioning: Vacuum is used to draw in the atomized fuel. This adjustable vacuum is generated by compressed air which causes the oil mist to condense via a filter. An annular lampis fitted which permits precise observation of the nozzle spray. The unit can be inclined towards the front to permit better observation of the injection chamber. An oil-level indicator shows whenthe collector must be emptied.
