Blue Fuels and Products

The new eni blu super+ petrol has high octane rating (100 RON) and excellent detergency properties.
The high octane rating showed increased power (up to 8%) and improved accelleration (up to 6%) compared to standard gasoline. The best performance was obtained without penalising fuel consumption.
The high detergency properties allow blu super+ to mantain the valves clean and remove deposits previously accumulated in vehicles run on commercial fuels. The immediate keep-clean effect reduces deposits by more than 95%.The clean-up test (M111 IVD - CEC F-20-98) showed that blu super+ can remove up to 80% of deposits on valves in vehicles run on reference fuel. The combination of these characteristics improves engine performance.

The new blu diesel+ is a fuel of higher quality, thanks to the excellent cleaning properties and high cetane number.
The excellent cleaning properties ensure the keep-clean effect, which is the maintenance of cleanliness in the injection system and of the maximum engine power.
Due to the clean-up effect, blu diesel+ guarantees a drastic removal of deposits on the injectors, allowing the Full Power Restoration. These effects were verified on a DW10 engine with Euro 5 injectors, as required by the CEC F-98-08 test.
The high cetane number allows easier cold starting and reduces noise and engine vibration. Road tests have shown that the continuous use of blu diesel+ could allow diesel fuel savings up to 4%.

In the field of automotive lubricants, the most significant products developed by R&D are in the high-performance range and have met both the requirements of wide market applications and the specific demands of the main car manufactures.

In particular, the following lines have been designed and delivered:

• 7005 and 7007 - SAE 0W-30 synthetic oils with High Fuel Economy performances and long drain intervals, specifically dedicated to the Volkswagen Group engines both petrol and diesel. Moreover 7007 has been qualified for use on diesel engines with pump-injector system and has become over the years, at first a factory and service fill oil, and then an original VW spare parts. For this application currently it is the only product worldwide recommended.
• Sint 2000 10W-40 - The flagship product for the partially-synthetic Passenger Car line has been constantly updated to fulfil the evolving performance requirements.
• Passenger Car Mineral Line - This sector has benefited by the upgrade of the formulation technologies and especially by the exploitation of a novel cost-effective additive system.
• Platform for high compatibility with aftertreatment systems and excellent fuel economy - New formulation technologies enabling the effective operations of advanced aftertreatment systems and enhancing the quality of lubricants with regard to the environmental impact (reduction of CO₂ emissions). In this product line innovative additives have been adopted with the outstanding contribution of the internal R&D know how. This new technology has recently generated (2009) two products claiming the ACEA C level for Euro 5 engines.
• i-Sint - In 2010 there was a deep restyling of the brand names for car lubricants. Under the common name i-Sint, the new line of car lubricants signed by eni was divided into three distinct areas:
  • i-Sint: high performance products to suit the needs of today's engines. The line includes lubricants designed for next-generation engines and for cars equipped with particle filters;
  • i-Sint Tech: products for customers seeking excellent quality, able to meet the specific needs of some of the most important car manufacturers;
  • i-Sint Professional: products dedicated to professionals.

Even for bitumen, Eni's R&D aims to innovative formulations, with high quality and low environmental impact, to achieve high performance products.
Two lines were developed:

Eliflex
These bitumens are a qualified response to the demand of road operators for mechanical strength, durability and safety. They are prepared according to a patented technology from appropriately selected bituminous components and adding a polymer elastomeric modifying agent in order to have:

• excellent characteristics of elasticity and resistance to permanent deformation, even at high operating temperatures
• greater resistance to fatigue and aging
• better behavior at low temperatures.

The process and engineering technologies allow to prepare a complete line of products, meeting all the market needs:

• Eliflex HD, MD and SF: hard, medium and soft modified bitumen, suitable for the realization of the layers constituting the whole package of roads;
• ELIFLX AM: high modulus modified bitumen, specific for structural improvements;
• Eliflex HE: extra hard modified bitumen with a high change degree for extreme applications - such as airport runways, race tracks, freight yards interchange;
• Eliflex HES: modified bitumen with high adhesive characteristics, particularly suitable for draining conglomerates and high durability layers.

RIGEBIT
From the experience of the Eliflex line, using a patented formulation with polymers, hydrocarbon waxes with high molecular weight and specific additives, it was possible to carry out a series of products with excellent flow and workability, with the following benefits:

• Lowering the temperature of preparation, paving and compaction of the conglomerate of about 30 ° C, with energy saving in all stages of processing;
• reduction of CO2 emissions;
• possibility of reusing materials milled from flooring, thus reducing the extraction of virgin materials from the quarry.

For their characteristics these products are optimally used in critical environmental conditions (at night or in winter) and in recycling of exhausted hot asphalt, allowing the regeneration of the milled material.
The line of products currently available cover the following market needs:

• RIGEBIT HM30: modified bitumen suitable for the construction of pavements subjected to very heavy traffic conditions.
• RIGEBIT 60: modified bitumen, which is also used in hot recycling operations, allowing to reuse up to 40% of material.
