The repair tester VEP-1000 for BOSCH VP37 pump simulates the outputs of an Engine Control Unit (ECU), to control fuel injection quantity by driving the proportional rotary-magnet actuator. The injection quantity consistency under different engine speeds or different fuel injection deliveries can be tested by the VEP-1000 tester.
Design Features
l Two user control modes
n Open-loop control mode
The angular position of the rotary-magnet actuator is controlled by manually setting the duty circle of the driving PWM signal.
n Close-loop control mode
The operator sets a target position of the rotary-magnet proportional actuator. The system adjusts the duty-cycle of the driving PWM signal automatically according to the real-time measurement of the angular position sensor.
l Monitor voltage signal of the angular sensor on the LCD screen
Button to enable or disable fuel injection cut-off solenoid on VP37 pump
