Premium diesel additives

Premium Diesel Additives are intended to allow product differentiation by the provision of additional technical features that can be advertised by the fuel marketers.

Infineum offers multifunctional diesel fuel additives (Infineum F series) which can be formulated to include the following features:

• Detergency
  Fuel injector spray patterns are key to an efficient combustion process in diesel engines. Deposition of carbonaceous, combustion waste products on the injector can have a detrimental effect on the spray pattern which may result in increased emissions and decreased fuel economy.
  
  

  Distorted spray pattern	Optimum spray pattern

  
  
Detergent additives help maintain an optimum fuel spray pattern resulting in:


• Reduced combustion noise
• Reduced emissions and black smoke
• Maintenance of the injector system in peak condition, preventing deterioration in fuel economy and extending vehicle life.
  
  
• Antirust
  The fuel distribution system, from refinery through to the combustion chamber of the vehicle, is susceptible to corrosion from water that may be present in the fuel. Antirust additives help reduce rust formation in fuel storage and delivery systems resulting in reduced maintenance of pipes and tanks and reduced risk of filter blocking due to rust deposits.
  
  
• Antifoam
  Antifoam additives help reduce the tendency of diesel to foam in fuel delivery systems resulting in faster and cleaner (no spillage) tank fill. Antifoam additives enable the maximum amount of fuel possible to be added during the fill stop.
  
  
• Fuel Stability
  Thermal and oxidative degradation of diesel fuel is a common problem which can result in fuel darkening, deposits, and filter blockage. Fuel stabiliser systems can reduce fuel darkening, reduce the risk of stalling due to filter blockage, reduce maintenance costs of replacement filters and ultimately contribute to less vehicle downtime.
  
  
• Demulsibility
  Diesel fuel containing polar molecules will form emulsions with free water. Demulsifiers prevent the formation of water/fuel emulsions.
  
  
• Increased Cetane Number
  Cetane number improver improves diesel fuel combustion characteristics resulting in:
  
  
  • Reduced starting time in cold weather
  • Reduced engine noise
  • Reduced white smoke during warm up
  • Reduced emissions
  • Maximum power
    
    
• De-icer
  Provides fuel “anti-icing” protection when free water may contaminate the fuel.
  
  
• Improved Lubricity Characteristics
  Lubricity improvers provide improved fuel lubrication characteristics to severely hydro-desulphurised fuels (e.g. ultra-low sulphur diesel fuel) and help prevent wear to fuel pumps and fuel injectors
  
  
• Improved Cold Flow Properties
  When middle distillate fuels are cooled to temperatures below their cloud points, wax crystals form within the fuel which can block vehicle fuel filters. Cold flow additives provide improved pour point and operability (CFPP/LTFT) performance which:
  
  
  • reduces the risk of wax plugging filters and lines
  • improves fuel handling
  • improves low temperature vehicle operability (as measured by CFPP and other cold flow performance tests)
  • may offer improved refining economics through upgrading of heavier products to the diesel pool (or kerosene upgrading to jet).
