Effect of the nozzle holder on injected fuel temperature for experimental test rigs and its influence on diesel sprays

Gimeno, Jaime; Marti-Aldaravi, Pedro; Carreres, Marcos; Peraza, Jesús E (SAGE Publications, 2018)

[EN] One of the test boundary conditions whose control is necessary for both experimental and numerical studies about the automotive engines research field is the temperature of the fuel inside the injector body during the ...
Experimental assessment of the fuel heating and the validity of the assumption of adiabatic flow through the internal orifices of a diesel injector

Salvador, F.J.; Gimeno, Jaime; Carreres, M.; Crialesi Esposito, Marco (Elsevier, 2017)

[EN] In this paper an experimental investigation on the heating experienced by the fuel when it expands through the calibrated orifices of a diesel injector is carried out. Five different geometries corresponding to the ...
Fuel temperature influence on the performance of a last generation common-rail diesel ballistic injector. Part I: Experimental mass flow rate measurements and discussion

Salvador Rubio, Francisco Javier; Gimeno, Jaime; Carreres Talens, Marcos; Crialesi Esposito, Marco (Elsevier, 2016-04-15)

An experimental study is conducted in this paper in order to assess the influence of the fuel temperature on the performance of a last generation common-rail ballistic solenoid injector. Mass flow rate measurements are ...
Fuel temperature influence on the performance of a last generation common-rail diesel ballistic injector. Part II: 1D model development, validation and analysis

Payri, Raul; Salvador Rubio, Francisco Javier; Carreres Talens, Marcos; De La Morena, Joaquín (Elsevier, 2016-04-15)

A one-dimensional model of a solenoid-driven common-rail diesel injector has been developed in order to study the influence of fuel temperature on the injection process. The model has been implemented after a thorough ...
Thermal effects influence on the Diesel injector performance through a combined 1D modelling and experimental approach

Carreres Talens, Marcos (Universitat Politècnica de València, 2016-11-02)

[EN] The injection system is one of the topics that has been paid most attention to by researchers in the field of direct injection diesel engines, due to its key role on fuel atomization, vaporization and air-fuel mixing ...
Thermal effects on the diesel injector performance through adiabatic 1D modelling. Part I: Model description and assessment of the adiabatic flow hypothesis

Salvador, Francisco Javier; Gimeno, Jaime; Martín, Jaime; Carreres, Marcos (Elsevier, 2020-01-15)

[EN] The fuel flow along common-rail injectors is usually treated as isothermal, although the expansions across the injector orifices lead to variations in the fuel temperature that in turn modify the fuel properties ...
Thermal effects on the diesel injector performance through adiabatic 1D modelling. Part II: Model validation, results of the simulations and discussion

Payri, Raul; Salvador, Francisco Javier; Carreres, Marcos; Belmar-Gil, Mario (Elsevier, 2020-01-15)

[EN] In this paper, a one-dimensional computational model of the flow in a common-rail injector is used to compute local variations of fuel temperature (including the temperature change produced upon expansion across the ...
