Abstract

Problema. Proveer una tecnología para mejorar más la economía de combustible. Solución. El puerto de entrada (24) se provee con un área de puerto cuadrada, la forma en sección transversal vertical en la dirección longitudinal (dirección de flujo de aire de entrada) del cual es sustancialmente cuadrado, y la abertura que conduce desde una abertura de acoplamiento del inyector (26) en puertos de ramificación (24b, 24c) se formó aproximadamente de manera completa dentro de las porciones de pared plana superior (122b, 122c) en áreas de puerto cuadradas de los puertos de ramificación(24b, 24c) en áreas de puerto cuadradas de los puertos de ramificación (24b, 24c). Al hacerlo, el tamaño del volumen muerto (92) se puede reducir al mínimo, comparado con que cuando se forma la abertura de acoplamiento del inyector en un puerto de entrada de la forma en sección transversal circular. Consecuentemente, la turbulencia del aire de entrada que fluye dentro del puerto de entrada (24), y particularmente dentro de los puertos de ramificación (24b, 24c), se puede reducir al mínimo, dando un buen mezclado de combustible y aire de entrada, y que mejora la eficiencia de combustión. La economía de combustible puede mejorar además como un resultado.
