ENVIRONMENTAL REGULATIONS AND NEW CHALLENGES FOR DIESEL WORKSHOPS
In recent years, European emissions regulations have introduced increasingly strict limits for internal combustion engines. In particular, the Euro 6 standard represents a turning point for the diesel sector, requiring manufacturers and workshops to adapt to new technical demands.
Injector maintenance plays a key role in this context: these components determine combustion efficiency and, consequently, emission levels. For workshops, this means updating procedures, tools, and spare parts in order to comply with regulations and avoid non-compliance risks.
WHAT DOES EURO 6 REQUIRE FOR DIESEL ENGINES?
The Euro 6 regulation, in effect in Europe since 2015 and progressively updated (Euro 6d-Temp and Euro 6d), aims to significantly reduce harmful vehicle emissions.
The main limits imposed by Euro 6 include:
- Reduction of particulate matter (PM), with values over 50% lower than Euro 5.
- Cut in nitrogen oxide (NOx) emissions, among the most harmful to health and the environment.
- Control of polluting gases under real driving conditions (RDE), not just in lab tests.
- Continuous monitoring through OBD (On-Board Diagnostics), which immediately detects injection system malfunctions.
These constraints make injector maintenance more delicate and complex, as even small errors or unsuitable spare parts can result in non-compliant emissions.
HOW EURO 6 CHANGES INJECTOR MAINTENANCE
Euro 6 diesel injectors operate at much higher pressures (up to 2,500 bar in the most modern systems) and with extreme precision in fuel delivery. This improves efficiency but also introduces new challenges for workshops.
Greater precision and tighter tolerances
Euro 6 injectors are designed with extremely tight tolerances. Even a small carbon deposit or an imperfect seal can compromise combustion and increase emissions.
New testing and calibration procedures
A suitable test bench is always needed to check injector flow, pressure, and response. Equipment like Hartridge or Bosch benches—available in REDAT-equipped workshops—allow the accurate testing required for Euro 6 systems.
Updated and certified spare parts
Using non-compliant or generic parts can lead to emission values above legal limits, invalidating the maintenance. That’s why REDAT provides reliable, tested components that ensure repairs meet regulatory standards.
THE ROLE OF REDAT CERTIFIED SPARE PARTS IN EURO 6 MAINTENANCE
Spare part quality is one of the most critical factors in ensuring Euro 6 compliance. REDAT is ISO 9001 certified, and its products are designed to operate under the most demanding conditions without compromising performance.
WHY CHOOSE RELIABLE SPARE PARTS FOR EURO 6?
➔ Reliability under high pressure: REDAT plungers, solenoids, and nozzles resist deformation and loss of precision.
➔ Perfect compatibility with leading injector brands (Bosch, Denso, Siemens, Delphi, Caterpillar, Cummins).
➔ One-year warranty on all products, confirming the quality of materials and production processes.
➔ Reduced malfunction risks, which could lead to non-compliant emissions and potential fines.
MISTAKES TO AVOID IN EURO 6 INJECTOR MAINTENANCE
New regulations demand greater technical rigor. Here are some frequent mistakes that workshops must avoid:
Reusing seals and O-rings → always replace with certified complete sets.
Superficial diagnostics → always use professional testers and test benches.
Use of incorrect spare parts → high risk of irregular emissions.
Inaccurate calibrations → each injector must be calibrated with millimetric precision.
Neglecting cleanliness → even minimal deposits can alter emission values.
LINKING REGULATIONS TO WORKSHOP REALITY: A PRACTICAL CASE
A concrete example involves the maintenance of Bosch CRIN4.2 injectors on Euro 6 engines. During servicing, a customer used generic seals that caused a pressure loss, enough to exceed the legal NOx emission values.
By replacing the seals with a REDAT kit and calibrating the injector on a Hartridge test bench, the issue was resolved, bringing the engine back within Euro 6 limits.
This demonstrates how the difference between a generic part and a reliable one is crucial not only for durability but also for regulatory compliance.
ADVANTAGES FOR WORKSHOPS USING REDAT CERTIFIED PARTS
Investing in updated tools and certified spare parts brings concrete benefits:
★ Satisfied customers: vehicles that pass inspection tests with no issues
★ Operational efficiency: fewer repeat jobs due to premature failures.
★ Competitive positioning: workshops operating to Euro 6 standards offer premium, reliable service.
