Repair
Testers for Electronic Unit Injectors
|
|
|
1. Product Functions |
| The
EUI repair tester consists of a mechanical cam box with EUI test
adapter kits plus EUI model specified adapter kits, and an
electronic controller. The cam box will be installed on a standard
high pressure pump test bench. The EUI being tested will be
installed in the cam box. The electronic controller provides the
synchronous signal to drive the EUI solenoid. The EUI fuel injection
quantities can be checked at given speeds and loads to judge the
quality of the tested EUI. |
2. Design Features
A silicon oil torsional damper is installed on the driving end of the cam shaft to reduce the pulsational unevenness of the cam shaft due to fuel injection.
A speed sensor is mounted on the cam box. Therefore, the driving signal is synchronous with cam shaft without the need for external speed sensor.
Modulated driving signal to ensure the safety of EUP solenoid.
The start of injection (SOI) angle and pulse width of solenoid driving signal are user adjustable.
Short
circuit protection for the output circuitry of the solenoid driving signal
3. Product Models
The standard cam box is designed to be stalled on a Bosch 815 pump type test bench.
The installation height of the EUP cam box (from the cam center to the top surface of the test bench) is 125mm.
The cam box may be customized for special required installation height.
