“…Mirsky [11] assumes that the combustion products undergo an isentropic process during exhaust. From the isentropic relations for an ideal gas, the following expression can be used to relate the masses at EVO and EVC:…”

“…En la metodología diseñada se usó el método desarrollado por Yun y Mirsky [4], el cual asume que los gases de combustión experimentan un proceso isentrópico durante la carrera de escape, de modo que la masa en el instante del cierre de la válvula de escape (EVC) puede ser determinada a partir de las correlaciones de gas ideal para este tipo de procesos entre la apertura de la válvula de escape (EVO) y el EVC, obteniéndose la Ecuación 7.…”

“…Existen diferentes métodos que permiten tener una aproximación de este parámetro a partir de variables como la presión en cámara y el volumen instantáneo. Yun y Mirsky [4] desarrollaron un método para estimar la masa de gases residuales, método que para Ortiz-Soto et al [5] presentó una mejor aproximación a las simulaciones realizadas para cuantificar este parámetro. La estimación apropiada de la masa total atrapada en el cilindro permite obtener resultados de validez técnica en el balance de energía, dado que la temperatura estimada en el cilindro depende de esta variable, y con ello diferentes parámetros que intervienen en el balance.…”

“…They are the closed-cycle portion using the ideal gas law, the exhaust event which uses an adaptation of the iEGR estimation equation by (Yun & Mirsky, 1974) presented above, and the intake event which specifies a "blending rate" based on the cylinder volume and valve events. Each of these regimes is shown in Figure 3-3 for a representative test condition, and are discussed independently below.…”
