Temas Avanzados en Motores de Combustión Interna es constituir una aportación a la literatura técnica en lengua castellana en este campo. Se ha intentado que el contenido de la serie sea un fiel reflejo de los últimos desarrollos científicos y tecnológicos den el campo de los motores térmicos, tanto en lo que se refiere a nuevos conceptos y desarrollos como a la mejor comprensión de los fenómenos básicos que determinan el funcionamiento del motor, bien mediante el uso de técnicas experimentales avanzadas, bien mediante el desarrollo y utilización de modelos. Las monografías se dirigen tanto a investigadores que trabajen en la Universidad o en la Industria, como a profesionales de la automoción. Las estrategias de post inyección han sido parte activa de las soluciones utilizadas en la reducción de las emisiones contaminantes de los motores diesel en la última década. Multitud de autores han estudiado sus efectos a lo largo de estos últimos años. El presente trabajo representa una contribución para la merjor comprensión de los fenómenos físicos involucrados en los procesos de combustión y formación de hollín con el uso de dichas estrategías de inyección, dando como resultado la aparición de dos fenómenos relevantes: la aceleración de la fase final del proceso de combustión, y una aparente desconexión entre la combustión del pulso principal y el pulso post inyectado.

This comparison reveals clear differences between the two corpora, with the textbooks containing a much higher proportion of concrete everyday words than the COBUILD texts and a lack of many of the common abstract words need for an understanding of the language of the news media. of certain of the linguistic criteria for text typology suggested by D.Biber. With the help of these criteria, it was possible to show that the textbooks tend to be interactive and to have situated content and reported style, while the COBUILD texts seem to be edited, to have abstract content and more immediate style. in terms of the linguistic differences between British and American English. It was found that the linguistic orientation of both corpora is overwhelmingly British. described above, among them a list of the 9330 textbook lemmas with a fequency of 5 or more. Each lemma appears with its frequencies from the textbook and the COBUILD corpora and a difference coefficient indicating its relative frequency in the two corpora.
