Frequently Asked Questions
How often should injectors be tested?
Regular testing is recommended during routine maintenance or when performance issues appear, typically every 100,000 km.
What are the most common injector faults?
Leaks, incorrect opening pressure, poor atomization, and electronic malfunctions in common rail systems.
What equipment do I need to test diesel injectors?
Workshops typically use pop-testers for mechanical injectors and digital benches for common rail systems.
Can I test both mechanical and common rail injectors with one setup?
Yes. DIT31 test bench covers both types, our solutions are designed for both solenoid and piezo common rail injectors.
How do you test a diesel injector?
Testing involves pressure verification, spray pattern analysis, timing measurement, and leak testing using specialized equipment calibrated to manufacturer specifications.
What's the difference between manual pumps and test benches?
Manual pumps provide basic pressure testing, while electronic test benches offer comprehensive analysis including timing, electric tests, peak pressure memory, and automated protocols.
Can TP03 integrate with existing pump systems?
Yes, TP03 functions as a precision digital accessory, enhancing existing manual pump capabilities with accurate pressure and timing measurements.
How do you test piezoelectric common rail injectors?
