“…Pint and Schock (2000) simulated piston ring wear by using a generalized total wear coefficient to account for all the wear mechanisms involved, including adhesive, abrasive, and corrosive wear. The wear mechanisms of piston rings and cylinder liner with the use of high-sulfur diesel fuel were also studied by Takakura et al (2005). They believed that the wear mechanisms with the use of high-sulfur fuel were dominated by a combination of corrosive wear and abrasive wear caused by the formation of aqueous sulfuric acid via acid condensation at the EGR cooler outlet.…”

“…Afortunadamente este hecho no suele ocurrir en los motores de pequeña cilindrada puesto que el reducido tamaño del turbogrupo hace que los rendimientos de compresor y turbina sean moderados, además en estos motores el egr se realiza en una zona de funcionamiento de baja carga y por tanto con dosados reducidos y bajas temperaturas de escape. No obstante, para evitar reflujos y permitir mayores tasas de egr se pueden adoptar soluciones tales como el estrangulamiento de la admisión [29] o el uso de sistemas auxiliares como el venturi [30][31][32], la válvula rotativa [33] o las láminas elásticas [34].…”

“…A partir del trabajo de Arnau [6], el código wam permite el uso los métodos de Lax-Wendroff [30] y tvd 2 [31] para resolver el problema de flujo compresible no estacionario en los conductos del motor. El método de Lax-Wendroff es más rápido en la convergencia hacia una solución final; sin embargo, se trata de un modelo de cálculo con menor estabilidad que los esquemas tvd [6].…”
