Read More About Our Diesel Test Equipment and Tooling

With modern diesel engines now being manufactured to Euro 6 specification settings on common rail injectors are more stringent than ever with adjustments made to within 1 micron (0.001mm).

Our Supply

DD supplies test equipment that allows the accurate adjustment, setting and testing of the injector to well within the manufacturers specified tolerances.

For common rail testing we have various stages depending on budget – from function testing to actual full test and repair including measuring on assembly for Bosch, Siemens and Denso.

For tooling purposes our wide range of stock covers engine work, work bench, and test bench. So for engine work, we have timing tools, timing kits and pins, sockets, spanners and insulated socket sets for the new breed of hybrid vehicles.

Bench Tools

Work bench tools include injector stripping and assembling plus pump strip and rebuild, catering for the majority of manufacturers equipment.

Test bench tools includes setting pieces, timing pins, special sockets, setting spanners and adjusters.

FAQs

What is required to test Euro 6 common rail injectors correctly?

To test Euro 6 common rail injectors accurately, you need advanced electronic diesel test equipment capable of simulating high-pressure operating conditions (often exceeding 2,000 bar). This includes a common rail test bench, injector coding capability (IMA/QR codes), and software that supports Euro 6 calibration profiles. These tools ensure injectors are tested under real-world emission-compliant conditions.

Why are Euro 6 injector settings more complex than earlier standards?

Euro 6 injectors require precise control over multiple injection events (pilot, main, post-injection & pre-injection), which reduce emissions and improve efficiency. Unlike older systems, they rely heavily on electronic calibration data and tighter tolerances. This means test equipment must measure extremely fine variations in fuel delivery and timing, making specialist tooling essential.

What role does injector coding play in Euro 6 systems?

Each Euro 6 injector is supplied with a unique calibration code (IMA, C2i, or QR code), which must be programmed into the vehicle’s ECU after installation. Diesel test equipment must be capable of reading, verifying, and in some cases generating or validating these codes to ensure optimal engine performance, fuel efficiency, and emissions compliance.

Can standard diesel test benches handle Euro 6 injectors?

Most older or basic test benches are not suitable for Euro 6 injectors. Euro 6 systems require high-precision measurement, advanced software protocols, and higher pressure capability. Upgrading to a modern test bench or adding compatible software/modules is often necessary to meet Euro 6 testing standards.

What tooling is essential for servicing Euro 6 injectors?

Key tooling includes specialist injector dismantling tools, torque-calibrated assembly tools, cleanroom-grade workstations, and micron-level measuring devices. Cleanliness and precision are critical due to the extremely fine tolerances in Euro 6 injectors, and improper tooling can lead to failure or non-compliance with emissions standards.
