CR914 Common Rail Fuel Metering Unit (IMV/VCV) Flow Performance Test Bench

CR914 Common Rail Fuel Metering Unit (IMV/VCV) Flow Performance Test Bench

The CR914 is an advanced, intelligent testing platform designed specifically for detecting the current-flow characteristics of fuel metering units (IMV, VCV, MPROP) used in high-pressure common rail pumps. Utilizing industrial-grade control technology and high-precision German flow sensors, it provides accurate data for both pre-research and factory inspections. The system is capable of testing both normally open and normally closed metering valves of various structural designs.

With its integrated PLC and touch-screen interface, the CR914 automatically collects, processes, and plots current-flow curves, generating comprehensive data reports. It supports PWM pulse width modulation drive signals and ensures stable oil pressure at 5±0.1 bar, making it an indispensable tool for fuel system component manufacturers and professional diesel repair centers.

• High Precision Measurement: Equipped with German high-precision flow sensors to ensure accurate readings at every test point (accuracy up to 0.1ml).

• Automated Data Analysis: Automatically generates and draws current-flow curves and data reports, judging the qualification of loop differences and measuring points.

• Versatile Testing Modes: Supports continuous testing, single-point testing, manual current adjustment, and reliability fatigue running functions.

• Advanced Control System: Features a robust industrial computer with PLC and touch-screen control for fast pressure regulation and stable performance.

• Comprehensive Protection: Integrated with multiple safety measures including infrared detection, safety light curtains, and automatic temperature control.

• Universal Database: Includes standard database functions for preparation, storage, statistics, and printing of test results.
