A Combination of Swirl Ratio and Injection Strategy to Increase Engine Efficiency

Olmeda, P.; Martín, J.; García Martínez, Antonio; Villalta-Lara, David; Warey, Alok; Domenech Llopis, Vicente (SAE International, 2017)

[EN] Growing awareness about CO2 emissions and their environmental implications are leading to an increase in the importance of thermal efficiency as criteria to design internal combustion engines (ICE). Heat transfer to ...
An Investigation of Radiation Heat Transfer in a Light-Duty Diesel Engine

Benajes Calvo, Jesus Vicente; Martín Díaz, Jaime; García Martínez, Antonio; Villalta Lara, David; Warey, Alok; Domenech Llopis, Vicente; Vassallo, Alberto Lorenzo; Vassallo (SAE International, 2015-09)

In the last two decades engine research has been mainly focused on reducing pollutant emissions. This fact together with growing awareness about the impacts of climate change are leading to an increase in the importance ...
Application of a zero-dimensional model to assess the effect of swirl on indicated efficiency

Broatch, A.; Martín, Jaime; García Martínez, Antonio; Blanco-Cavero, Diego; Warey, Alok; Domenech, Vicent (SAGE Publications, 2019-10)

[EN] Increasing internal combustion engine efficiency continues being one of the main goals of engine research. To achieve this objective, different engine strategies are being developed continuously. However, the assessment ...
Evaluation of swirl effect on the Global Energy Balance of a HSDI Diesel engine

Benajes, Jesús; Olmeda, P.; Martín, J.; Blanco-Cavero, Diego; Warey, Alok (Elsevier, 2017)

[EN] In the last years, a growing interest about increasing engine efficiency has led to the development of new engine technologies. Since air motion in the chamber is a key issue in internal combustion engines to improve ...
Experimental study of the influence of exhaust gas recirculation on heat transfer in the firedeck of a direct injection diesel engine

Torregrosa, A. J.; Broatch, A.; Olmeda, P.; Salvador-Iborra, Josep; Warey, Alok (Elsevier, 2017-12-01)

[EN] Emissions control is a key topic for internal combustion engine development. One of the most widespread technologies to reduce the formation of nitrogen oxides is the recirculation of exhaust gas to the engine intake. ...
Impact of swirl on in-cylinder heat transfer in a light-duty diesel engine

Broatch, A.; Olmeda, P.; García Martínez, Antonio; Salvador-Iborra, Josep; Warey, Alok (Elsevier, 2017)

[EN] One of the key strategies to reduce CO2 emissions is to improve the efficiency of engines in order to diminish fuel consumption. A way to increase engine efficiency is to reduce the heat losses. Internal heat transfer ...
Implementation of two color method to investigate late cycle soot oxidation process in a CI engine under low load conditions

López, J. Javier; Martín, J.; García Martínez, Antonio; Villalta-Lara, David; Warey, Alok (Elsevier, 2017)

[EN] Soot emissions from diesel engines are an important concern in meeting emissions regulations. Soot emissions are the result of two competing processes: soot formation and soot oxidation. Mechanisms of soot formation ...
In-cylinder soot radiation heat transfer in direct-injection diesel engines

Benajes Calvo, Jesus Vicente; Martín Díaz, Jaime; García Martínez, Antonio; Villalta Lara, David; Warey, Alok (Elsevier, 2015-12)

The efficiency and CO2 are one of the main concerns of automotive manufacturers. There are several strategies under investigation to solve this problem. In the present work, the research effort has been focused on improving ...
Swirl ratio and post injection strategies to improve late cycle diffusion combustion in a light-duty diesel engine

Benajes, Jesús; Martín, J.; García Martínez, Antonio; Villalta-Lara, David; Warey, Alok (Elsevier, 2017)

[EN] Nitrogen oxides (NOx) and soot emissions are the most important pollutants from direct-injection diesel engines. In particular, soot formation and oxidation determine the net engine-out soot emissions. These phenomena ...
