Effect of Fuel Properties on Injection Characteristics of Four Different Diesel Injection Systems.

Abstract

Four diesel injection systems were selected for evaluating the effects of fuel properties on diesel spray characteristics. The selected injection systems were from the following Navy engines: the Detroit Diesel Allison 4-53T, the Detroit Diesel Allison 4-71TI, the Cummins NH-220, and the Westerbeke 4-108. Fuel properties which were examined were viscosity and specific gravity. The injection systems were operated on nine test fuels covering a broad range of viscosity and specific gravity. High-speed movies were taken of the fuels being injected into a high-pressure environment. Penetration and cone angle data were reduced from the movies and used as a basis for fuel-to-fuel comparisons. In addition, drop size distribution were obtained for the Westerbeke 4-108 injection system operating on four fuels with different viscosities. (Author)
