“…This study lead Karim [3] to propose the widely-accepted three-stage description of the dual-fuel combustion process (see above). The second example of a single-zone model was proposed by Pirouzpanah [11], and rests upon this three-stage description, whereby a modified version of the Whitehouse and Way [12] combustion pattern was applied to determine the mass of both diesel and the gaseous fuel that was burned in each time step.…”

“…Many combustion models employ the corresponding Weibe functions or a modified Whitehouse and Way [12] method. However, it was established in section 4.1 that part of Karim's description is based on a modelling artefact induced through a switch in γ values.…”

Citation: STEWART, J. and CLARKE, A.A., 2010 Abstract: Dual-fuel engines are modified compression ignition engines where the primary fuel source is provided by a gaseous fuel, and ignition is provided by a reduced quantity of diesel: the pilot. The generally accepted description of the subsequent combustion process is that initially, around half of the pilot will burn and entrain some gaseous fuel in an overall rich process. Then the remaining pilot fuel burns with an increasing amount of the primary fuel until the final stage where a flame propagation process engulfs the remaining gaseous fuel. In this paper a three-zone model will be derived, benchmarked against data obtained for diesel combustion, and then applied to experimental data from a dual-fuel test program. The three-zone model will also be used to investigate the assumptions made regarding the mechanism of dual-fuel combustion proceeding in three-stages. It will be demonstrated that evidence was scant in support of the accepted description of three stages of dual-fuel combustion in a direct injection engine. The conclusion of this work is that that the dual-fuel combustion may be better considered as a diesel combustion process, where the gaseous fuel modifies the reaction zone surrounding each igniting droplet of the pilot fuel.

“…Se han desarrollado numerosos estudios encaminados a determinar la posición del PMS tanto de tipo experimental [40,[47][48][49] como termodinámico [41][42][43][44][45][46][50][51][52][53].…”

“…En conclusión, la detección experimental es una técnica bastante precisa cuando se hace mediante los equipos adecuados, aunque debido a su laboriosidad, en la práctica no se emplean en el diagnóstico de la combustión. Tinaut y otros [49] proponen una alternativa a la detección directa del PMS. Su propuesta se basa en la medida del régimen instantáneo, y aunque más rápido y menos costoso que la medida directa, los autores reconocen que el método es menos preciso.…”

El trabajo desarrollado en la presente tesis doctoral está encaminado a profundizar en el diagnóstico de la combustión a partir de la señal de presión en el cilindro en los motores Diesel de inyección directa. Para ello, se dispone del conocimiento previo sobre adquisición de señal de presión y diagnóstico de la combustión mediante el modelado termodinámico existente en el grupo de trabajo en que se ha desarrollado....miraba estupefacta los agujeros negros en la carcasa del motor yéste seguía funcionando como si tal cosa, a toda madre y ni un rastro de humo siquiera...
