Panda Diesel's EUI EUP HEUI Tester series provides specialized diagnostic solutions for electronic unit injectors and pumps. This range includes robust testers engineered for systems like the CAT 320D HEUI Pump, ensuring precise calibration and performance validation. Our equipment delivers accurate data on injection timing, pressure, and fuel delivery for Caterpillar, Cummins, and other major brands. Designed for reliability and ease of use, these testers are essential tools for workshops aiming to maximize engine performance and efficiency through professional-grade diagnostics and maintenance.
Defining the Technology
An EUI (Electronic Unit Injector) and EUP (Electronic Unit Pump) Tester is a specialized diagnostic bench used to calibrate and validate the performance of these specific mechanical-electronic diesel injection components. Unlike common rail systems, EUI/EUP systems integrate the pump and injector into a single unit, driven by the engine's camshaft, and require specialized equipment for off-engine testing.
Core Diagnostic Functions
The tester's primary role is to simulate engine conditions to measure critical parameters. It checks injector response times, fuel delivery volume across different pressure ranges, and leak-down rates, ensuring each unit meets precise OEM specifications before installation.
Essential for Heavy-Duty Maintenance
This tool is indispensable for repair shops servicing heavy-duty trucks, industrial engines, and marine applications from manufacturers like Caterpillar, Cummins, and Detroit Diesel, ensuring reliable engine operation and optimal fuel efficiency.
