1. Product Description POWERGUARD 6061 Powerguard 6061 is a chlorine free, multifunctional diesel additive package, developed by Innospec to enable refiners to maximise diesel quality from available feed stocks, to assist blenders in meeting national fuel specifications and to provide marketers with a cost effective means to differentiate their fuels from competitors products. 2. Treat Rate Powerguard 6061 is recommended for use at the following treat rates depending on the specific performance requirements. Keep clean performance in XUD9 and DW10 = 200 Clean-up performance in DW10 = 275 3. Key Functions At the specified treat rates, Powerguard 6061 offers many benefits. These include: reduced nozzle fouling in terms of XUD9 performance protection against power loss in modern High Speed Direct Injection Engines protection against fuel filter plugging caused by high speed direct injection engines protection against diesel fuel foaming improved corrosion protection protection against fuel/water emulsions complete compatibility with the constituent materials of the engine and fuel system
4. Physical Properties Typical physical properties of Powerguard 6061 are presented below: Property Powerguard 6061 Method Appearance Clear Amber Liquid Visual Density @ 15 C, kg/l 0.90 ASTM D4052 Viscosity @40 C, cst 3.6 ASTM D445 Flash point, C (PMCC) 63 ASTM D93 Pour point, C <-39 IP15 / ASTM D97 5. Supporting Information Powerguard 6061 has been widely proven in extensive engine tests to assess deposit control performance together with detailed laboratory performance and no-harm testing. Performance benefits and no-harm attributes of the packages are illustrated below. 5.1 Peugeot XUD9 IDI Performance XUD9, Keep Clean Testing The detergency performance of Powerguard 6061 has been evaluated using the XUD9 engine. Nozzle fouling tests were performed using the Peugeot XUD9 1.9 litre engine according to the CEC F-23-01 test procedure. Fuel Reference Diesel Fuel Treat rate of Powerguard 6061, Fouling @ 0.1 mm needle lift, % 0 76.3 200 3.3 275 1.0
Nozzle Fouling @0.1mm Needle Lift, % 80 70 60 50 40 30 20 10 0 0 200 275 Powerguard 6061 Treat Rate, As can be seen from the above data, Powerguard 6061 at the recommended treat rates provides excellent performance in the Peugeot XUD9 engine test.
5.2 Peugeot DW10 HSDI Performance Work has been carried out to develop an industry standard test representative of modern HSDI engine technology in addition to the current XUD9 test procedure. This engine uses a Peugeot DW10 engine which utilises injector design of prototype Euro 5 technology. The standard test procedure as outlined in the CEC F-98-08 test method however has only currently been validated, in the form of available precision data, using a fuel containing 1ppm zinc. Tests have been carried out to demonstrate the performance of Powerguard 6061 over a range of treat rates. The performance data generated using the zinc containing reference fuel is shown below; DW10, Keep Clean Testing, Zinc Reference Fuel Testing according to the CEC F-98-08 test procedure has been performed with Powerguard 6061 at a range of treat rates. The data generated using the CEC reference fuel of RF-06 + 1ppm Zinc is demonstrated below. As can be seen from the above data, the typical DW10 requirement of <2% power loss for modern diesel fuels is comfortably achieved with 200 of Powerguard 6061.
DW10, Clean-up Testing, Extensive testing using the Peugeot DW10 HSDI engine has also been carried out to also determine the optimum treat rate, which provides rapid clean-up in the shortest test duration. All tests have been carried out using the CEC reference fuel DF79 + 1ppm Zinc and the chart below demonstrates the excellent performance of Powerguard 6061 As can be seen from the data, clean-up in the DW10 and restoration to 100% power is possible within the standard DW10 test duration.
5.3 Antifoam Fuel foaming is a well understood phenomenon with diesel fuels, particularly at the point of delivery on the forecourt. Innospec s diesel additive formulations contain an effective anti-foam additive to ensure that foam build-up is effectively controlled and suppressed. Antifoam benefits include: more complete tank filling in reduced time reduced fuel spillage reduced customer concerns; hands, shoes and clothing stay cleaner improved forecourt cleanliness Work has been carried out using industry standard laboratory tests to demonstrate the effectiveness of Powerguard 6061. Using the BNPe laboratory test, it can be seen that effective control of diesel fuel foaming can be achieved. Typical results are shown below. Treat rate, Foam Height, mls Foam Height, % improvement Collapse Time, s Collapse time, % improvement Base fuel 0 118 -- 23 -- Powerguard 6061 200 54 54 5 78 Treat rate, Foam Height, mls Foam Height, % improvement Collapse Time, s Collapse time, % improvement Base fuel 0 126 -- 31 -- Powerguard 6061 275 50 60 4 87 As can be seen from the above data, improvements in both foam volume and foam collapse time are observed with Powerguard 6061. 5.4 Corrosion protection The ability of the proposed diesel performance additives to prevent corrosion in wet diesel has been demonstrated using the National Association of Corrosion Engineers (NACE) corrosion test. In this test, a steel probe is immersed in a mixture of the fuel and distilled water, maintained at 60 C. The steel specimen is then rated using the NACE scale. Additive Treat rate, Steel Corrosion D665(A), NACE rating Base fuel 0 E Powerguard 6061 200 B++ Additive Treat rate, Steel Corrosion D665(A), NACE rating Base fuel 0 E Powerguard 6061 275 A
At the recommended treat rate, Powerguard 6061 provides excellent protection against corrosion. 5.5 Water reaction Water reaction testing performed using the ASTM D1094 test procedure has demonstrated that the proposed formulation will not cause problems of water emulsions. The data generated below displays typical performance with Powerguard 6061. Treat rate, Volume Aqueous Layer at 5 min Time to 20ml of Water Interface Rating Fuel Rating B7 Base fuel 0 18 >5m 3/4 2 Powerguard 6061 200 20 1m05s 1b 2 Powerguard 6061 275 20 1m 1b 2 As can be seen from the above data, Powerguard 6061 has no adverse effect on the water separation of a base fuel. 5.6 Lubricant Compatibility Using the SEDAB lubricant interaction test procedure an evaluation of the lubricant compatibility of the two formulations have been performed. In this test procedure, the time taken for 500ml of fuel/lubricant mixture to filter is recorded. The maximum allowable filtration time is 300s. The test data generated is shown below; Fuel Additive Volume of Fuel Filtered, ml Filtration time, s Base fuel None 500 58 Powerguard 6061 500 60 The above data demonstrates that the additive formulation does not contribute to lubricant compatibility, when evaluated under severe lab testing protocols.
6. Handling, storage and use Handling In general the formulation should be treated as a flammable, high viscosity, hydrocarbon liquid. In case of accidental spillage: Personal precautions: eliminate all sources of ignition. Put on approved personal protective equipment before entering an affected area. Environmental precautions: stop further leakage if without risk. Prevent spread of spilled material with sand or earth. If contamination of drains, streams or water courses occurs or is likely, warn the local Water Authority immediately. Cleaning up: recover any free liquid or absorb on sand or other suitable absorbent and place in a sealed container. Remove contaminated material to safe location for subsequent disposal. Additive compatibility Innospec fuel additives have been successfully and extensively used in retail fuels world-wide for many years, and have demonstrated no compatibility problems in use. Materials compatibility Powerguard 6061 is fully compatible with engine and fuel system materials, including 'Viton' seals and graphite laden PTFE. A range of other plastics and rubbers were examined by monitoring changes in mass, dimensions, appearance and hardness caused when these materials are immersed into a series of commercial additive treated fuels, including certain oxygenated components. The plastics included nylon 66, nylon 11, nylon 12, polyoxymethylene homopolymer known as Acetal, high density polyethylene (HDPE), polybutylene terephthalate (PBT), polyurethane (PU) and polyester (PET). The rubbers included nitrile, nitrile-pvc, epichlorohydrine and fluorosilicone.
