An experimental study of gasoline effects on injection rate, momentum flux and spray characteristics using a common rail diesel injection system

Payri, Raul; García Martínez, Antonio; Domenech Llopis, Vicente; Durrett, Russell; Plazas, Alejandro H. (Elsevier, 2012-07)

A comparative study using diesel fuel and gasoline has been conducted focusing on the injection process. In this paper an experimental study has been carried out comparing the effects of the different fuels on the mass ...
Effects of Injection Nozzle Geometry on Spray Characteristics for Direct Injection Diesel Engines

Tamaki, Nobushige; Harada, Takato (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] The purpose of this study is to improve the spray characteristics of a direct injection Diesel nozzle. Spray atomization of the multi-hole atomization enhancement nozzle, which was invented in previous studies, is ...
Effects of varying the liquid fuel type and air co-flow conditions on the microscopic spray characteristics in an atmospheric annular co-flow spray burner

Cardona, Santiago; Payri, Raul; Salvador, Francisco Javier; Gimeno, Jaime (Elsevier, 2023-03-01)

[EN] The atomization process is critical for combustion systems since it directly influences emissions and perfor-mance. Thus injection system should provide the spray required structure and characteristics, e.g., angle ...
Engine combustion network: Influence of the gas properties on the spray penetration and spreading angle

Payri González, Francisco; Payri Marín, Raúl; Bardi, Michele; Carreres Talens, Marcos (Elsevier, 2014-02)

In this work, three Engine Combustion Network (ECN) single-hole nozzles with the same nominal characteristics have been tested under a wide range of conditions measuring spray penetration and spreading angle. n-Dodecane ...
Experimental Investigation on the Early Stage Spray Characteristics with Biodiesel and Diesel

Yu, Shenghao; Yin, Bifeng; Wen, Shuai; Li, Xifeng; Jia, Hekun; Yu, Jianda (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] The early stage spray characteristics have a great impact on the secondary atomization progress, and thus affect the engine combustion and emission performances. The experimental investigation of the early stage ...
Investigation of the urea-water solution atomization process in engine exhaust-like conditions

Payri, Raul; Bracho Leon, Gabriela; Gimeno, Jaime; Moreno-Gasparotto, Armando Enrique (Elsevier, 2019-11)

[EN] The injection process of the urea-water solution (UWS) determines the initial conditions for the mixing and evaporation of the fluid in the selective catalytic reduction system. In this study, the liquid atomization ...
