Effect of a novel piston geometry on the combustion process of a light-duty compression ignition engine: An optical analysis

Pastor, José V.; García Martínez, Antonio; Mico Reche, Carlos; De Vargas Lewiski, Felipe; Vassallo, Alberto; Pesce, Francesco Concetto (Elsevier, 2021-04-15)

[EN] The development of new piston geometries has shown great potential to achieve the low levels of soot emissions required by regulation. Thus, the present paper aims to characterize the influence of a new piston design ...
Impact of counter-bore nozzle on the combustion process and exhaust emissions for light-duty diesel engine application

Payri, Raul; De La Morena, Joaquín; Monsalve-Serrano, Javier; Pesce, Francesco Concetto; Vassallo, Alberto (SAGE Publications, 2019-01)

[EN] This article describes the main results of an investigation about counter-bore injector nozzle impact on the combustion process in a modern Euro 6 diesel engine. First, hydraulic and spray visualization tests have ...
Influence of the radial-lip concept design to achieve ultra-low soot emission reductions: An optical analysis

Pastor, José V.; Micó, Carlos; De Vargas Lewiski, Felipe; Tejada, Francisco J.; Vassallo, Alberto; Pesce, Francesco C.; Belgiorno, Giacomo (Elsevier, 2023-08-01)

[EN] Nowadays, internal combustion engines must reduce pollutant emissions to achieve the upcoming strict regu-lations in the transport sector. In this context, new hardware designs have shown great potential to reduce ...
Mixture formation and combustion process analysis of an innovative diesel piston bowl design through the synergetic application of numerical and optical techniques

Millo, F.; Piano, A.; Roggio, S.; Pastor, José V.; Micó, Carlos; De Vargas Lewiski, Felipe; Pesce, F.C.; Vassallo, A.; Bianco, A. (Elsevier, 2022-02-01)

[EN] The optimization of diesel engine piston bowl geometries has a crucial role in improving the near-wall flame evolution for better air/fuel mixing and soot reduction. With these aims, an innovative piston bowl for a ...
Numerical and optical soot characterization through 2-color pyrometry technique for an innovative diesel piston bowl design

Piano, A.; Roggio, S.; Millo, F.; García Martínez, Antonio; Micó, Carlos; De Vargas Lewiski, Felipe; Pesce, F. C.; Vassallo, A.; Bianco, A. (Elsevier, 2023-02-01)

[EN] The development of innovative diesel piston bowl designs has shown significant improvement of the near-wall flame evolution, resulting in lower fuel consumption and engine-out soot emissions. With this aim, a novel ...
