High Pressure Testing is Nothing Without Control

Posted by Lee Jacobs on March 18, 2019

The significant advancements in injector technology to meet the Euro 6 emissions legislation include increased fuel injection pressure, optimised nozzle spray angles and patterns to enhance combustion, and how many injections are possible per combustion cycle. However, another technical advancement that is not so well documented is closed loop electrical drive logic to provide accurate control during the injection event and digital rate shaping to configure the profile of the injected fuel during the combustion stroke.

Understanding this essential engineering concept is vital to unlocking true control of high pressure testing. So how has Hartridge responded to provide a leading aftermarket test solution and what advanced controls have been implemented to achieve this?

Two Coil or Not Two Coil | Dual Coil Injector Technology

Posted by Lee Jacobs on February 15, 2019

Dual coil technology is fast becoming the new “buzz” word within the diesel common rail (CR) aftermarket. Due to its advanced pressure and injection control techniques, along with twin channel injector firing protocols, it initially presented a challenge for Hartridge when developing a test solution for the Sabre CRi Expert; but as we have said in previous blogs we will take the path to achieve best results even if this isn’t the easy path!

Common Rail Injector Coding & The Hartridge Mission

Posted by Lee Jacobs on February 12, 2019

The Hartridge mission, which we boldly accept, is to ensure that fuel injection components are tested according to OEM standards. We seek to do this to the highest criteria with the correct methods, even if these methods mean we can’t take a quick & easy path to providing workshops with what they need to achieve these OEM standards.

So for us CR injector coding; if it is to be done correctly, is simply a means of ensuring that an injector which passes the Hartridge test plan is then calibrated to perform as originally specified by the OEM.
