ACEA E9-16 is a new mid SAPS1 requirement Ultra High Performance Diesel (UHPD) lubricants for use in mid drain applications.
ACEA recommend ACEA E9-16 for use in vehicles fitted with advanced exhaust aftertreatment systems for the reduction of particulate matter (DPFs) and the oxides of nitrogen (EGR and/or SCR) in combination with low sulphur diesel fuel.
The main physical and chemical requirements anticipated for ACEA E9-16 are shown below:
|HTHS viscosity||CEC L-36-A-90||mPa.s||≥ 3.5|
|Sulphated Ash||ASTM D874||%wt||≤ 1.0|
|Phosphorus||ASTM D5185||%wt||≤ 0.12|
|Sulphur||ASTM D5185||%wt||≤ 0.4|
|Evaporation loss (NOACK)||CEC L-40-A-93||%||≤ 13|
|Total Base Number||ASTM D2896||mgKOH/g||≥ 7|
The requirements of the Cummins ISM test place emphasis on enhanced soot related wear control for ACEA E9-16. The removal of the Mack T-11 and inclusion of the Mack T8-E test now aligns E9-16 with other E categories with regard to soot handling performance requirements.
E9-16 anticipates baseline performance for Euro VI emission legislation, which has led to extensive adoption of DPFs on vehicles in Europe.
Note 1 : SAPS refers to Sulphated Ash, Phosphorus and Sulphur, the levels of which are often restricted in the latest performance specifications.
A number of changes to the requirements for ACEA E9-16 have been introduced in the ACEA 2016 issue of the oil sequences.
The changes for ACEA E9-16 are summarised below:
|Test||Change for ACEA 2016|
|CEC L-112||New elastomers for the oil elastomer compatibility tests|
|CEC L-109||New oxidation test with biodiesel -Check|
|CEC L-104 (OM 646 Bio)||New CEC L-104 Biodiesel impacted piston cleanliness and engine sludge test - E6/E9 only|
|Shear Stability||Test can now be run using CEC L-014-93 or ASTM D7019 for 30 cycles, and ASTM D7019 only for 90 cycles|
The relative performance diagrams presented below compare Lubrizol's interpretation of the performance requirements of ACEA 2016 E9-16 oil sequence with the ACEA 2016 E7-16 oil sequence.
This comparison illustrates how both sequences are expected to provide similar performance in terms of bore polishing and piston cleanliness. However, ACEA E9-16 is expected to provide a higher level of performance in terms of corrosion protection, soot handling, aftertreatment compatibility and wear protection than ACEA E7-16.
The relative performance diagrams presented below compare Lubrizol's interpretation of the performance of the ACEA 2016 E9-16 oil sequence with the ACEA 2016 E6-16 oil sequence. The introduction of new biodiesel tests are reflected across the relevant axis in the performance tool.
This comparison illustrates how ACEA E9-16 is expected to provide a greater level of corrosion protection, wear protection and soot handling than ACEA E6-16. ACEA E6-16 has a higher level of aftertreatment system compatibility, piston cleanliness and bore polish resistance.
