The higher the cetane # the quicker the fuel will ignite. Must have a cetane number of at least 46. • Detergency: Two are required 1) Detergent component: Attacks the deposits and helps break up the particles that create deposits for a cleaner flow of fuel throughout the fuel system. 2) Injection Stabilizer: Delivers high level of detergency that will act as both an antifoulant and detergency package. Protects fuel from coking, when exposed to extreme pressure and heat generated by the HPCR engine. It must show the ability to prevent and clean-up IDID deposits that include soap/metal carbonaceous and amide laquer. • Lubricity: Friction-reducing agents providing better protection against friction and wear of the fuel pump than typical #2 diesel fuel. Fuel must have 460 HFRR (wear scar measurement). All fuels are currently required to have a 520 HFRR. The lower the score the more effective the lubricity improver. • Demulsifier: Demulsifiers force water to the bottom of the tank, allowing for easy drainage and removal. This prevents unwanted moisture from being carried through the fuel system and reduces the volume of water entering the combustion chamber. Fuel must contain a demulsifier to separate water versus an emulsifier that disperses water through the fuel.
