cetane number
Fischer-Tropsch (F-T) diesel fuel is characterized by a high cetane number, a near-zero sulphur content and a very low aromatic level.
      
Effect of paraffins C10-C13, C14-C17, C18-C23, tert-butyl hydroperoxide, cumyl hydroperoxide, and isopropyl nitrate as cetane number improvers for summer- and winter-grade diesel fuels, added in amount of 0.4-5 wt %, is studied.
      
On the basis of published data, parametric equations relating the basic physicochemical characteristics of off-standard diesel fuels, i.e., the cetane number, the density, and the sulfur content, were derived.
      
When cetane indexes calculated according to the simultaneous equation method were applied to the fatty acid mixtures, the agreement with those experimentally determined was approximately the error of determination of the cetane number.
      
Neither the lower cetane number of POD fuel nor its emulsification with water presented obstacles to the operation of the diesel engine during a series of steady-state engine tests and the twenty-hour endurance tests.
      
Fuel properties, such as cetane number, also were investigated.
      
In particular, they enhance phase stability and improve the cetane number in ethanol-diesel fuel blends.
      
Other properties of the esters, such as kinematic viscosity, heating value, and calculated cetane number, also were determined.
      
Other properties of the esters, such as kinematic viscosity, heating value, and calculated cetane number, also were determined.
      
These properties included cetane number (CN), low-temperature properties, (kinematic) viscosity, lubricity, and surface tension.
      
The increase in NOx emissions might be an inherent characteristic of soybean oil's polyunsaturation, because the level of saturation is known to affect the biodiesel's cetane number, which can affect NOx.

Laboratory-calculation method for determination of cetane number of gas condensates
      
When cuts with an end point of tEP >amp;gt; 360°C are contained in the fuel, such quality indexes as the sulfur content, solid point, and cetane number become significantly worse.

Organic peroxides are examined as additives that increase the cetane number of diesel fuels.
      
After one measurement which lasts on the order of 140 min, it is possible to determine the n-paraffin content, distillation curve, cetane number, density, and flash point of a sample.
      
Additionally, specifications for lower aromatics content and increased diesel cetane number are expected.
